[Gimp-user] Graphics Muse Tools 0.4 - build updates
FYI - I'd been contacted by a user that my old Graphics Muse Tools no longer built with Gimp 1.2. After much delay, I fixed that. They should work fine with 1.2 and GTK+ 1.2 now. The build environment should also be easier to deal with - the config.h only needs to know where the gtk-config and gimp-config scripts are located. If they're already in your path, you probably shouldn't have to do anything. Hope someone still finds these useful. BTW, the collection of brushes and patterns I had is also on the web site now as well. http://www.graphics-muse.org/source/GFXMuse/ -- Michael J.

[Gimp-user] changing font colors
Thus spoke Jim Clark [EMAIL PROTECTED] Thanks for the suggestions, solved my problem quickly and easily. Some worked better than others, though I am sure it was my ignorance that did it. But I would love to see somewhere a little more explanation of the screen mode on the bucket fill. I'm looking at p 126 of The Artist's Guide to the Gimp and all it says is screen brings out highlights. What did I do when I followed your directions? In simple terms, Screen adds color and brightness to dark regions. Whereever the existing pixel is already above a threshold (defined by the color being used as the screen), nothing is added. Where it is under, varying amounts are added, depending on how dark the pixel is. So the black regions got full blue color. The gray regions got blueified. The effect is that a photograph, for example, will get lightened and somewhat colorized, making it appear washed out. I didn't go into excessive detail in the Artists' Guide because I wanted to keep things very introductory. It wasn't meant to be as encompassing as Grokking is. I did, however, have to read through the code to figure out what each mode did. There wasn't any other documentation at the time that described them, and I had never (and still haven't) used Photoshop. -- Michael J.

[Gimp-user] fonts on Red Hat 7.2 resolved
From: Jim Clark [EMAIL PROTECTED] To: Gimp [EMAIL PROTECTED] Subject: [Gimp-user] Perennially confusing font problems Hate to ask it, as it has been discussed many times and there are many web pages on it, but I can't get it to work. RedHat 7.2 using GIMP 1.2.3 I have some additional fonts I'm trying to install. I have added the path to this directory to my /usr/X11R6/lib/X11/fs/config file by just adding the directory with a comma to the list. Red Hat 7.2 uses XFree86 4.1, I believe. This combination now uses the X font server - xfs - instead of handling fonts internally as it did in previous versions of the XFree86 server. So when you make changes to the fs/config file you need to restart the font server: /etc/rc.d/init.d/xfs restart You should be able to do this without restarting your X session. One quick way to check if you're already using the font server (aside from checking for it with the ps command) is to query the X server: xset q If you see something like this in the output: Font Path: unix/:7100, ... then you're using the font server. That unix/:7100 is the port the X server is using to talk to a font server. While on the topic of fonts, there seem to be many redundancies and many more not too worthwhile. Other than today's action, I have the standard RH install. Are there any of these directories I can comment out to reduce the clutter? The 100dpi stuff is unnecessary. Its just a duplicate of the 75dpi stuff but for a different resolution. Your monitor is likely at (or near) 75dpi, so you don't need the 100dpi directory. I don't know about any others that might be duplicates. -- Michael J.

[Gimp-user] DPI issues
Thus spoke Hermann Otteneder [EMAIL PROTECTED] hi, (i hope my english is understandable) Pretty close. :-) i've made a logo with the gimp with the hight of 482 px. this works with a resolution of 72 dpi. But i must change this to 150 dpi! after a i've made this i had to korrekt the size to the hight of 482px again. but the logo is now much higher and also if print the logo altough the gimp shows in the info window the correkt size! what is this?! have someone info fpr me please... The trick to creating a logo for print is to first compute its size in the print resolution. For example, if you need a 150 DPI 5x6 print, then you need to create an image of (5*150)x(6*150) = 750 x 850 pixels. This is the size of the image must be no matter what resolution you set for that image. If you created a 72DPI image that was 482 pixels tall and then change the DPI to 150, the print will be pretty small. If you want exactly the same dimensions on the screen (at 72DPI, 482 pixels) as on the printed page, you need to scale the image by (150/72) = 2.083 times. Therefore your new height needs to be 1004 pixels. -- Michael J.

Re: [Gimp-user] 4 color book covers
Thus spoke John Culleton Very good! Now, when you laid out your tiff, of course you had an allowance for the thickeness of the spine, based on the printer's ppi. Did you also leave an allowance for the thickness of the cover itself? (Sorry it took so long to reply) No. I'm not sure why I'd need to. The width of the spine was enough to cover that. And did you add anything to the nominal width height for trim? Yes. The amount depends on what the printer asks for. I produced background images that would cover the trim or bleed. So if the image wasn't large enough for that, I just resized the canvas and then resized the background. Everything else remained the same. Note that in the version I used for my book, I couldn't do this as easily as you can now. In other words, for 5.5 x 8.5, with a ppi of 500 and 250 pages, is the width of the tiff exactly 11.5 inches or a little more? Is the height 8.5 or a little more? I did my calculations more simply: front width x front height = front and back sizes spine size = spine width x spine height Total size = front size + back size + spine size Add appropriate amounts for trim/bleed. Make the artwork on layers with the background used for adjusting for bleed and trim needs. Center the rest of the layers appropriately on the background. Thanks so much for your help. No problem.

Re: [Gimp-user] FAQ answers
Thus spoke John Culleton The preferences I referred to are for PS output and include such items as: Encapsulated Postscript (my preference) Zero horizontal and vertical offset (my preference) Inches instead of pixels for dimensions (my preference) The Preferences dialog doesn't cover these details. I don't mind specifying PS output. It's these other details that have to be reset in the same way on every run. Hmmm. I guess there may be a bug (or feature, depending on your point of view) where file plug-ins don't maintain their last setting in the gimprc file. Also, the file-format specific file plug-ins are the place where preferences of this nature must be set. It's a trade off for how versatile plug-ins can be (supporting another format means dropping in another plug-in instead of recompiling all of GIMP). What probably needs to be addressed is how well (or even if) file plug-ins (which are kind of special plug-ins from a developers perspective) save their last set configurations. I haven't checked if there is a bug written against this issue. It is probably worth while to write such a bug report if there isn't one yet since it's a reasonable request and a useful feature for future releases. Of course, this feature may already exist for the PS file plug-in but its just not being used correctly. I haven't verified that possibility yet (I don't use the PS output format much). -- Michael J.

[Gimp-user] More FAQ answers
Thus spoke Steve Crane [EMAIL PROTECTED] Here are a few ideas for questions for the new FAQ. 1. Can I use brushes from other software such as Photo Shop or Paint Shop Pro with the GIMP? Not that I'm aware of. I know you can't drop those brush files into GIMP's brush directories and have them just work. If a file plug-in exists that can read those brush files then you will be able to read them in and then save them into GIMP's native brush file format. But I don't know of any brush file plug-ins for other application's brushes. 2. How can I ensure that certain of the GIMP's windows, for instance the Levels or Crop and Resize Information windows, always open in the same position on screen? In short, you probably can't. You *might* be able to do so if 1. the developers gave each window a special name of its own and 2. your window manager allows you to save position information about those specially named windows. If #1 is true (and I don't know that it is), then in Sawfish (which is commonly used as the GNOME window manager) you can click on the title bar of a window (I think it's a right button click) to get a menu. At the bottom of that menu you have the option of choosing History information to be saved, such as position and geometry of a window. Select Save position. That *might* work. But no promises. Other window managers may offer similar features, but many do not. Caveat gimper. -- Michael J.

[Gimp-user] FAQ answers
Thus spoke [EMAIL PROTECTED] Hi! Here are some questions I have: *) Where can I find good gimp tutorials? Good is relative, but here are some pointers to get you started. http://www.graphics-muse.com/cgi/gmcat.pl?id=11 *) How close in functionality to PhotoShop is the gimp? You can do in GIMP most of what you can do in Photoshop. There are some caveats: Photoshop handles 16 bit color, Pantone and CMYK conversions - GIMP does not. Photoshop has a way to record your actions - GIMP only allows you to redo the last action (so far). GIMP has features Photoshop does not: Scripting Networked access Batch mode The trick is to expect your techniques to be similar between the two applications, but not identical. *) What versions of PhotoShop .PSD files are supported by the PhotoShop plug-in? Unknown. I guess I could read the code and find out, but I'm too lazy right now. It's the holidays. :-) *) How can I change the foreground color of some text to a pattern? The easiest way to do this is to start with text on it's own transparent layer. If you do so, then you can simply select Alpha to Selection in the Layers menu and do a Bucket Fill using a pattern instead of a color. If you don't have your text on a layer by itself like this, then you need to make a selection of the text. Selection techniques are many, and are likely to be one of your most valued skills as you get more involved in your artwork. *) What are layer masks and how do they work? They are cardboard cutouts that determine which part of the layer will actually be used. In the layer mask white areas designate areas of the layer that are visible (and/or combined with other layers) and black areas are masked out. To create a mask, just start painting in the layer mask with either black or white. Note that gray areas (places where pixels are mixed between black and white) in the mask make the corresponding pixels in the layer partially visible (aka partially transparent). *) How does the Xtns/Script-Fu menu differ from the Script-Fu pop-up menu? Huh? I'm not sure what the Script-Fu pop up menu is. *) Is it possible to align text along a curve in an image? If so, how is it done? It's done with a filter currently. See Xtns-ScriptFu-Logos-Text Circle This only works around a single arc, so it's not what you might expect, but it's a start. *) How can I find out the step-by-step process to make the logo effects in the Xtns/Script-Fu/Logos menu? I can see the resultant layer data, but have NO idea of how to do that myself. Read the code. Really, that's how pretty much everyone else learned. ScriptFu code is regular text that you can read. But it's a programming language. If you want to know how the techniques were discovered by the ScriptFU programmers, well, that's probably just experience. Lots of time fiddling with existing scripts or techniques to invent new ones. *) What does feathering mean? It means making the edges of a selection soft. In brief, it allows pixels within the feathered region to go from fully selected to not selected. If you feather a distance of 10 pixels for a circular selection then 5 pixels toward the inside of the selection will be fully selected and, as you move outward, the pixels are considered less selected. Being less selected is essentially like be more transparent. What this means in practice is that if you fill the selection (or cut it out) you get soft edges. In a fill of a feathered selection, the color flows from the selected color towards the existing colors in the layer. *) What books on the gimp are recommended? Beginner and intermediate level books would be great. Can't answer that. I have two published, so I'm a bit biased (though I think you can only actually get one of them these days). Carol's new web site has some listed (and the site design is rather nice - hope to see it go live soon!) - mmmaybe.gimp.org I think is the URL. *) Where can I find online resources/tutorials on creating animations with gimp? I think that link I gave earlier has some animation tutorial links on it. There aren't many tutorials on this subject yet. Thus spoke Nathan Carl Summers [EMAIL PROTECTED] OK here is my FAQ: How does one set defaults in Gimp for e.g., output formats? See File-Preferences. However, the default format is XCF which is GIMP's built in format to save layer information. To specify a different output format you either append the appropriate suffix to the filename (and let GIMP guess which format that means) or set the option menu to the format you want to use. Other defaults are configurable in the Preferences dialog. Hope that helps a little. -- Michael J.

[Gimp-user] More FAQ answers
Thus spoke zeus [EMAIL PROTECTED] Here's some question from me. 1. How to costumize Gimp Interface in Linux? GIMP uses GTK+, so it can use it's own gtkrc file to customize the interface. I think there are some prebuilt themes around, but I never use them. 2. Is Gimp providing gamut warning like in Photoshop? No. 3. How much layer, alpha channel gimp can handle? I'm not sure there is a coded limit to the number of layers. A cursory look at the layer code doesn't show one that I can find, but maybe I'm missing it. A practical limit will be based on canvas size and available memory. The larger the pixel dimensions, the more memory you'll need per layer. At least if you want to work moderately quickly and not wait for data to be swapped between memory and disk constantly. There is one alpha channel per layer. 4. Who create Gimp mascot?

My directory listing shows this font: /usr/local/gimp-1.2.3/freefont/brushstr.pfb but the text tool does not find this or the other freefont files. Any hints on how to correct this? The text tool in the Toolbox doesn't know about fonts directly - it has to ask either the X Server or xfs (X Font Server, which you may or may not be running). To get this font known to the Text tool you need to add the directory to the X Server font configuration (see /etc/X11/conf) or the xfs configuration (I can't remember off hand where this is kept - try man xfs). Then restart either the X server or xfs. Finally, restart the GIMP. Hope that helps. -- Michael J.

[Gimp-user] Graphics Muse Tools CD Version 2.0
I'll keep this short. Not sure if it would have been more appropriate/acceptable for the GIMP Announce list or not. Version 2.0 of the Graphics Muse Tools CD for Linux is now available. I've added 3 new Graphics Muse Plug-Ins (GFXLayers, GFXMerge, and GFXShapes) as well as updated the older 'Muse plug-ins (GFXArrows, GFXCards, GFXTrans and GFXDodge). Presets are available for those plug-ins that they make sense in and I've standardized the UI for all of these. The CD has over 100 plug-ins, over 100 brushes and over 100 patterns aside from the 'Muse plug-ins. This release has specific builds for Red Hat, SuSE, Mandrake and Debian. The older Win32 edition is also available but without the updated and new 'Muse plug-ins. I can't add those to the Win32 version cuz I don't know how to build GIMP plug-ins for Win32 yet. I'm a Unix hack. Cost: $24 for Version 2.0 of the CD. $15 for version 1.0 of the CD. Both plus shipping and applicable taxes. Source included for open source plug-ins.

Re: [Gimp-user] Re: CinePaint and Film Gimp
keep the project focused. One can create boards as much as one likes, this won't change nor create a single line of code or code-change. You couldn't be more blind here, Marc. The board members, as a requirement for participation on the board, could be required to take coding responsibility for a certain part of the application - perhaps filters or maybe (if they're qualified) something internal. You see the board as suits. You miss the point of their purpose or their possible makeup and duties. But, like I said, you are entitled to your opinion. And I encourage you to share it. It's how things get changed. And if it doesn't help the people who write the code (e.g. by getting specifications or the like), then I don't see why such a thing should be founded in the first place. Any authority granted to such a group would have to be to the benefit of both the developers and the user community the developers serve. If this group fails either, it fails in its mission. So what are the benefits of a board for the developers? How would that help them? How would such a board counter the frustration on the side of developers that a board exists that has power but no obilgations? Where does it get it's rights from? Who has to submit to it's decisions? How is it elected (if at all)? The only two questions I haven't answered here are the last two. The board gets its authority from the developers (any group of governors gets its authority from the governed or they cannot lead) who must be willing to abide by the boards decisions for the general good of the project. The board would be elected either by the developers directly (which is probably not the best solution but might be an interim solution till all parties are comfortable with the workings of the board) or by open elections, with the developers votes being weighted slightly more than an end users vote.

[Gimp-user] re: Laying out book cover
On Thu, 2004-02-26 at 14:00, John Culleton [EMAIL PROTECTED] A book cover consists of three panels, from left to right: the back cover, the spine and the front cover. I plan to lay these out on three separate images and knit them together. It is simple in Gimp to make each panel the exact dimensions needed. What is not so easy is to line them up exactly, left to right, with no overlap and no space in between. Vertical alignment is also critical. You don't actually have to split first then rejoin. You can do it all as one big image and then, if necessary, split it. I did that for my first GIMP book, The Artists Guide to the GIMP. I've also done it for some CD covers. Is there a way, other than drag and drop, to accomplish this precise alignment? Is snap to grid the best tool or is there another way? There are some layer alignment tools in GIMP 1.2, but I found them less than ideal for many of my situations. You can find them in the Layers menu (in the Canvas menu) at the bottom of the menu under Align Visible Layers I ended up writing GFXLayers, which provides visual interaction and a host of ways to align layers. Interestingly, this seems to be the plugin I use more than of the others I've written. I didn't realize how important it would be to me. GFXLayers is part of the Graphics Muse Tools CD (www.graphics-muse.com/gfxmuse/gfxmuse.html) If you have the memory, however, doing all the work in a single image is highly preferrable. I just think its far easier to work that way. I also haven't looked at how layer alignment tools may have improved in 2.0 yet - I just haven't been using 2.0 much yet. -- Michael J.

[Gimp-user] GIMP Articles - Request for Ideas
First, a little background: I've been writing a column for LinuxFormat (a UK magazine) for about a year and half now. It is mostly about GIMP but every so often I cover other topics like Inkscape or Ming (the Flash API) pr CSS or other graphics related topics. I've also started work on a column for another magazine, Tux Magazine, which will be published by SSC (the Linux Journal publisher) starting in February. This column, too, will focus on GIMP and desktop graphics issues for the end user. Now on to the real issue: After having written about GIMP almost non-stop since about 1996 (countless articles and two books) I'm starting to run dry on topics. The magazines seem to be happy with my work, but I get almost no feedback from readers so it's hard to tell if the articles are useful or not. And with two columns on the subject it's getting hard to not cover the same thing twice in a short period of time. What I need to know is what readers want - what problems do they have using GIMP, what techniques do they want to learn, what projects are they trying to work on? Where and what do you need help with? The only requirement for these two magazines is that the questions are about using GIMP on Linux (I couldn't help with detailed stuff on Windows anyway since I don't use that platform) and that they are generally more end-user oriented than developer oriented articles. I also try to cover both 1.2 and 2.0 since there are still a lot of users out there who have not upgraded. While I can't offer a free copy of the magazine (I don't carry that much clout) I can offer to give you thanks in the columns for your suggestions (assuming the publisher doesn't have a problem with that, which I don't think they will though I still need to clear it with them). So, if anyone has suggestions for topics related to GIMP please send them my way. If you have a favorite plugin you think should be covered or a tool that needs explaining or a How did they do this? question about some image made with Photoshop, let me know. I can even throw in the occasional interview of important person X if you think that would be interesting - you supply the name of X. :-) I'll do my best to answer as much as I can.

The Graphics Muse Tools are a set of plugins (C source) for GIMP 1.2. They've been around for at least 4 years now. I haven't had time to port to GIMP 2.x yet, but its definitely on my todo list. My personal favorite of these is GFXLayers, which is an interactive layer alignment tool. I use it far more than any of the others. There are no binaries for this, however. You have to build them from source. I did release the binaries as shareware on a CD and as downloads for a time, but nobody wanted that so now they have a modified BSD license and are available in source code format only.

My XNotesPlus is also imake based and I know it builds on just about all Unix/Linux platforms (or at least no one is reporting problems recently). To my knowledge the only current problem with portability is that the imake templates related to building man pages have changed for some distributions of Linux, probably the X.org based distributions. XFree86 based distributions should be okay. As soon as I get a chance to try the build on my newly installed FC2 I'll fix the problem with the man page rule that causes the build to break on other systems. At least I'm assuming its a change to the imake templates that is causing the problem. I've run into this issue before in various forms. You didn't advertize them much, did you? I discovered them only recently when hunting for plug-ins to build... I posted to Freshmeat, c.o.l.a and a few other places. I always post updates to my open source software on Freshmeat.

[Gimp-user] Announce: Graphics Muse Tools V3.0.0B1 - ported to GIMP 2.2.3
I spent last week porting the Graphics Muse Tools to GIMP 2.2.3. All the C plugins work pretty much as with GIMP 1.2 though there are a few minor functional bugs (see the bug page on the web site). There shouldn't be any crashes - at least none that I know of. I also cleaned out the old gimppreview that I had been using. I now use GdkPixbuf's along with Gimp's builtin thumbnail function that returns a pixbuf. That means GFXLayers is much less weighty - no more carrying around a ton of widgets for the previews. GFXTrans also benefited from this. I still have to pull out the deprecated features of both GIMP and GTK+, however, which is why this is a Beta release. If anyone wants to try these, you can pull the source code tarball from the web site or check it out of CVS. Source should build on Unix/Linux boxes (but I've only tried it on Linux). I don't have a clue how to build this for Windows or MacOS X (though I'd love to try the latter). http://www.ximba.org/gfxmuse/download.html Please let me know if you try them and most especially if you find bugs. If you can, please log the bugs in the bug db on the web site. FYI: these are no longer shareware, they are open source.

Can you give us a url? http://www.ximba.org/gfxmuse/gfxmuse.html Links to the download page, wiki, etc. are in the upper right corner. I tested the web site design under Firefox and IE (don't remember which version, but it was on WinXP). It might have problems rendering correctly under other browsers, though I tried to make it W3C compliant to some extent (probably got a few pages still to debug). The plug-in most asked for is GFXArrows, which draws arrows in varying shapes. Who'dda thought that one would be the popular one? The one I think is most useful is GFXLayers. It allows you to visually align layers in all sorts of ways, interactively, using thumbnails of the layers. It's not the best UI design, but it works well. Maybe if I get some feedback on the problems with the UI I'll be able to make it easier to use. GFXShapes needs thumbnail support. I need to add GdkPixbuf support to it for showing the page preview layout, similar to the way GFXLayers lets you drag layer previews around the page. It probably needs a way to easily add new, prebuilt shapes. GFXShapes was my answer to the common question How do you draw simple shapes? GFig is the normal tool for this, but I guess some people find it daunting to use. It's not *that* hard. :-) GFXTrans is best for doing multiple rotations for animations. The builtin rotation transform for GIMP is better for simple layer rotations. GFXMerge is the result of a posting someone put on one of the mailing lists asking for a way to split layers out into their own images or to merge layers from one image into another. It's very good at merging (splitting is broke in the beta but will probably be fixed soon), though I don't know how often anyone needs that. GFXCards lets you duplicate an image onto multiple cells, like for printing business cards, or create a printable image for use with greeting cards using an existing image for one side of the card. I use it mostly for business cards. It's a brute force approach, creating a big image at the correct DPI. A better method would be to generate a PS image that can be sent to the printer using a single copy of the orignal image. That would sure be a lot less memory intensive. Most of these (or is it all? I can't remember) are supposed to allow you to save your presets as XML files and reload them later. This is good for GFXShapes and GFXArrows, for example. Unfortunately, in the beta release the presets may not be working. I'll get that fixed. I doubt its a big problem - they worked fine under GIMP 1.2. And...my most profound thank you for converting your shareware into an Open Source application. Really, really really! Nobody was paying for them anyway. Just saves me the trouble of trying to build it for multiple platforms. It's a lot of work maintaining a bunch of different distributions like that. :-) I was also maintaining ports of a ton of plug-ins I found on the net as part of the original Graphics Muse Tools CD because they were not available in binary format for end users. But alas, few people paid for that so I dropped support for those other plugins. Way too much work for one guy. Now I just maintain the ones I wrote. Hope you find them useful.

Layers can be positioned interactively by dragging them around the preview or they can be positioned using a set of predefined toggles. And yes, this will allow you to center a specific layer on the image. Just click on the layer name while you hold down the Ctrl key (to make it the anchor layer) and choose Centered from the Anchor Position toggles. Changes are immediate.

Once you know where things are in the GIMP, then reading Photoshop texts can help quite a bit in learning basic image editing techniques. Complex tasks are mostly a matter of putting together lots of basic techniques. That is, essentially, what many filters do for you. When reading Photoshop tutorials, try to break them down into their basic processes, then convert that to their equivalents in GIMP. Don't get bogged down because Photoshop has fancy filter Blah but GIMP doesn't. Try to understand what Blah *is actually doing* and find the equivalent set of basic filters and tools in GIMP that will do the same thing. Hope that helps a little. -- Michael J.

me wrong - you *can* do this. Look at how well O'Reilly does with it's texts. But a GPL'd GUM is a *lot* of work for print publication. An alternative is to focus a GPL'd text on some smaller aspect of GIMP, like one of the builtin scripting languages, a set of specific filters or maybe using GIMP in a particular industry. At least that way you're not competing directly with the GUM and have a better chance on recouping costs (plus paying a few salaries along the way) even when the text is also freely downloadable. From my point of view, I try to avoid talking about GIMP as the end topic and rather talk about doing real work with GIMP as just one of your tools.

Re: [Gimp-user] Copy the alpha channel from an image to another
On Mon, 2007-02-12 at 23:50 -0800, Germain Le Chapelain [EMAIL PROTECTED] I would like to know who to copy the alpha channel of an image to another image. 1. Merge visible layers of the source image. 2. Copy visible layer of source image 3. Create new image for destination (as in File-New). 4. Add a layer to destination image 5. Delete background layer in destination image 6. Add black layer mask to only layer left in destination image. 7. Make black layer mask active drawable. 8. Paste into destination image. 9. Anchor to active drawable (re: mask). 10. Apply layer mask. Now the destination image (at least in that one layer) has the same alpha as your source image. Steps 4-5 could be: 4. Add alpha channel to background layer 5. (delete this step) Should also work in both 2.2 and 2.4. I tried this with a simple white image (single layer) using a gradient in a layer mask to create the source image. I then applied the layer mask in the source image to put the alpha into the layer itself. When this layer was copied to the black layer mask of the destination, the visual appearance was correct. When I saved both files (after applying the mask in the destination) they have the same file size (as expected) but they are not binary identical when saved as either XCF, TIFF or PNG. Not sure why (maybe some metadata differences?). I did notice that the pasted copy had a selection outline that was not the full size of the source image (both images where the same size). So even though I did a Select-All, Edit-Copy (I also tried Edit-Copy Visible), it appears to only have picked up to a certain transparency level in the copy. Or maybe it's just that the marching ants only recognize up to a certain level when pasted. Maybe one of the developers has some insight as to why the source and destination wouldn't be identical in this case. -- Michael J.

Also, it will be some time before all the major distributions get updated to the requirements for 2.4 and have those distributions propogated to the general public. So even though 2.4 is due soon, 2.2 isn't disappearing soon from a great many users desktops. In the end, though, the changes for 2.4 don't greatly affect the tutorials.

When you need the selection again, open that file, go to the Channels dialog, choose that channel and click on Channel to Selection at the bottom right of the dialog (next to last button on the right in GIMP 2.2). Or you can drag that channel from the original image (from the Channels dialog) into the image you need it. When you do that, it gets created as a new layer in the new image with visibility set to whatever the channel visibility was set to in the original image. You can then use normal selection tools to convert that into a selection in the new image. It's also recommended that you name the channel before saving the image to an XCF file.

True, but that's something you learn to do after you've learned what shadow maps do and I don't think the original poster was familiar with those yet. My feeling is that it's a little easier to understand what the shadow map is doing if you can see it's nothing but levels of light and dark (re: a desaturated layer). Adding color is an extension to that. I actually learned to do exactly what you suggest by first learning shadow maps and then tinkering with the process. So I guess you can modify my answer to change always to often, especially when you're first learning shadow maps. :-) -- Michael J.

[Gimp-user] Possible issues with 2.4
Before I report them as problems, I thought I'd check with other users. First, I can't seem to get the Perspective Clone to perform the way it does in the video tutorial. The cloning operation doesn't appear to lean in the direction I've adjusted the perspective handles. I'm wondering if I'm misunderstanding the use of the handles or something. Anyone else having problems using it? Second, I've noticed that the Healing tool clones garbage pixels after a while. It starts out working okay. After a short time, the first click to clone is fine, but if I hold down the shift key and then click again to perform a straight line clone operation the pixels cloned along this line are (for lack of a better term) garbage. Is anyone else seeing this? I've noticed that the problem is not consistant - it doesn't always show up. FYI - I'm using 2.4.4. I've posted examples of each on my web site: Clone problem: http://www.graphics-muse.org/source/perspective.png In this example, I expect the perspective to be toward the left and back but that's not what happens when I paint the cloned area. Healing tool problem: http://www.graphics-muse.org/source/healing.png The problem is visible on the right side where three straight line operations have started adding colored pixels to the otherwise black and white image. Note that while it may appear the source location is too far right and the operation may have gone off the right edge of the image, it hasn't as the image extends to the right beyond the visible canvas border. So it's not a boundary edge problem. -- Michael J.

The perspective worked intuitively and the heal seemed to work no matter what I did I've assumed that, like the video tutorial, if I pull the upper left and right handles down toward the center of the canvas that I'm setting the far end of the perspective view. So a square cloned with the perspective clone tool would have it's left and right sides aligned with the left and right sides of the perspective box. This is my impression of what should happen based on the video tutorial. Is this how it's supposed to work? If so, it's not doing that, as the sample picture shows. In fact, it almost looks like the application of the perspective is opposite of what I'd expect. And the size of the clone object is not always what I expect. Sometimes it gets larger. Sometimes (as in my example) it gets smaller. What deteremines the cloned object's size? From the example I've created I can't deteremine what the expected results should be given the movement of the handles to specific locations. -- Michael J.

One pixel = one dot. Most monitors give you between 72 and 100 DPI, or dots per inch. You'll notice that you have a monitor that is 15-24 inches across depending on how they measure such things. So you have 72*15 = 1080 dots across the screen for the 15 monitor. Now how do you convert that to printing for a book? Well, in the book you want the same image but at a smaller size. A typical book is likely less than a typical piece of paper (around 8.5). In fact, the actual image size is likely to be around 2-4 across. So what DPI do you need to squeeze 1080 dots into (splitting the difference) 3? 1080/3 = 360DPI. If you set your image resolution (using Image-Scale Image and changing the X and Y resolution) to 300 DPI, then your image will be 3.6 across. How do I know this? 1. Create a new image (blank white background) at any size. 2. Image-Scale Image, then set the width to 1080 pixels. Click on Scale to scale the image to that size. 3. Image-Scale Image, then set the resolution to 300 for the X and Y resolution. Click on Scale to change the image resolution. 4. Image-Scale Image, then change the options menu next to the Height field from pixels to inches. Now you can see how wide your image is going to be when it's 1080 pixels across. Clear as mud?

You can scale up the screen shot but I'd only double it's size once to produce a larger print image at high DPI. Even then, you're likely to have a less than ideal print image. Scaling up is not a good thing with raster images.

How do I get the Gimp to exactly track that hex colour - is there somewhere I can input it as a value and just it promulgated through the graphic at the existing saturation and lightness? You need to map the RGB values from the HTML to HSL. Manually, I'm not sure how to do this, but programmatically there is a function in libgimpcolor called gimp_rgb_to_hsl_int(gint *r, gint *g, gint *b) that will do this for you. You pass in the RGB values and you get back (in the same variables) the HSL values, repsectively. Once you have the HSL values you can call the Hue-Saturation tool via the PDB to apply to your masthead. If you're writing a GIMP plugin in C, you just need to use pkg-config --libs gimp-2.0 (on Fedora, other distros may use a different pkgconfig name for GIMP) to retrieve the libraries required for compiling your plugin. This will automatically include libgimpcolor. You can probably do this in Script-Fu or Python, but I don't know those languages or their requirements. You can probably do it in Perl but I'm not sure if the Perl support was updated for GIMP 2.4 or not. I think it was, but it's not included in the standard distribution. It's interesting that the Plugin Browser allows you to browse the APIs for the various plugins but there is nothing that lets you browse library calls that can be made directly from scripts or compiled plugins. There doesn't appear to be any documentation on this. I wonder if it's automatically generated by the build into HTML or man pages?

I would think (based on my limited knowledge of the subject) that GEGL would make this easier in 2.6. 1) It interacts with everything the same way the paint brush and pencil do. Draw squares, circles, etc., directly on to current layer. UI controls are similar to other paint programs... dragging boxes, etc. In the current release you could implement a tool that simply drops one of a set of default shapes into the canvas. The shapes would be based on paths. Essentially this tool is nothing more than a convenience item for creating a path manually. This could probably be implemented as a plugin as well, though if you did that I don't think (but am not sure with 2.4) that you can place that as an icon in the Toolbox. FWIW, my GFXShapes plugin will do vector shapes without paths, but you can save the shapes as presets (re: files). Presets are not saved as part of the image file, however.

Based on your description, I believe you'll be happiest working with Color Balance for this problem. However, adjusting lighting can mean a lot of things when working in a raster image editor like GIMP. Once you've become comfortable with Color Balance, you can try using Curves, Levels and the host of other dialogs available from the Colors menu applied to a selection of pixels from your image in order to adjust what visually appear to be lighting elements in the canvas. Alternatively, you can apply lighting effects by using layers and adding black or white filled selections that are blended (using Layer Modes) to lighten or darken regions of a canvas. There are also some filters under Filters-Light and Shadow that can be used to change the apparent lighting in the image. Drop Shadow and Lighting Effects are probably the two most widely used here.

This assumes you have a monitor profile correctly set for your monitor, however. In general, if you don't know about color profiles you can just say yes to convert it and then forget about it. Profiles are only relevant to those who are keenly interested in exact color reproduction between an input device (camera, scanner, etc.) and an output device (monitor, printer, etc.). The average person at home probably won't notice much or probably care that much if the colors are a little off. If you want to learn more about color profiles you can start with the Color Management section of the Preferences dialog. Profiles are a way of making sure the color reproduction is accurate from the device that acquires the image to the tool that edits the image to the device that outputs the image.

These ttif files have embedded exif information, and every time I save these files; it seems that the exif information will be stripped. I have done some tests on jpeg files; gimp will not strip the exif information. How can I correctly deal with the exif in tiff by using gimp? I can't say if the TIFF file plugin supports this or not but there are some options on how to deal with the situation if it doesn't. First, load the TIFF images and then save them in JPEG at 100% quality. Technically that should be equivalent to TIFF since no compression is performed but I can't guarantee that. To convert back to TIFF you can use ImageMagick's convert tool. According to this discussion: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1t=11600 convert will retain EXIF data. This is true as long as you're simply converting formats and not resizing (such as creating thumbnails). Converting file formats is as simple as convert file.jpg file.tif By the way, if I save these tiff images as another files, will gimp also strip the icc profile? (ps, will gimp strip the icc profile in jpeg?) I looked at using ICC profiles last month in an article I did for Linux Format magazine but I don't think I checked if the profiles were retained when saved. I think I assumed (bad idea) that they were. You'll simply have to try it and see. GIMP does support retaining ICC profiles when you open files that contain them. You're typically queried when you open the file if you want to keep it over convert it to GIMP's built in profile. When will the gimp support the 16bit per channel color depth? When it's ready. :-) Actually, integration of the GEGL libraries is underway and a first release with GEGL support is due in the next release (due out soon but one can never assume when soon might arrive). I don't know if 16 bit channels are to be included in the next release (though I don't believe they are), but one of the purposes of integrating GEGL was to allow for higher color depths.

Also, I will also check that if your ideal will work or not. I'm worried about that gimp can not even read the exif in the tiff file such that your approach will not work at all. I wasn't that impressed with the TIFF file plugin though I use it to save lossless screenshots for articles. If you are worried it doesn't read the exif data you can try converting to JPEG first using ImageMagick and then loading it that way. I believe the JPEG plugin supports the EXIF data.

However, I can't work out how to adjust some of the more complex options, such as the direction of brushing and the distance between brush strokes, as described in steps 8 and 9 of the tutorial. How do I do this in the GIMP? You'll want to create a GIMP Brush Pipe for this. In the brush dialog, open the Pencil Sketch brush as an image (right click on the brush icon in the dialog to get a menu for that). Delete all but two layers. Make one layer a left to right slant and the other a right to left slant (this effectively removes the brush shape from the original brush). Save the image as a brush pipe to your .gimp/brushes directory using .gih as the suffix for the filename. A dialog will open that allows you to configure the brush characteristics. Set the spacing to 50 percent (or whatever you feel appropriate), the number of cells to 2 and the first entry for Ranks to 2 and Angular. Put Stitch in the Description so you can find this brush later. Save the changes and then reload your brushes dialog. Look for the new Stich entry. Stroke your path using this brush. You'll have to play with the size of the brush. You may need to make multiple versions at different sizes to get the right effect.

It's common to need a feature like this but the solutions vary depending on the environment in which the image will be used. To my knowledge there are no off-the-shelf GIMP plugins/filters that provide the functionality you're requesting. That doesn't mean one doesn't exist. I've just not heard of any. Basically, I've got a bunch of pictures from a party/event that I want to do several things to: 1) Resize to 4x6 @ 300 PPI 2) Add a sllightly transucent ~ 1 white bar on top of the image (accross the bottom). 3) Over the white bar, on the left, place a small 1x1 logo. 4) Over the white bar, centered on the remainder, put the names of the people in the photo. (Reducing text size if needed to fit on one line.) 5) Over the white bar, centered on the remainder, put the name of the event on the next line. 6) Add a black border to entire image. 7) Export as JPEG. There is a CSV file that contains the names of the people in each photo to file name mapping. (One line per image file.) Can this be automated with the GIMP? Yes, if you're familiar with one of the programming languages supported for GIMP Plugins (C, Python, Script-Fu by default - there may be others). You'll need to become familiar with the plugin API. In 2.6, look under the Help menu for Procedure Browser. The way you use these is dependent on the language you choose. If you intend to use these images on the web you might be better off using dynamic support for this feature, such as what you see with NextGen Gallery, a plugin for Wordpress (blogging software for the web). On the web you can use code to overlay text onto graphics without actually modifying the image itself. In this way you can edit the text displayed without having update the image. For an example of how this works you can view my Dept 56 Galleries: http://www.graphics-muse.org/wp/?page_id=119 (view these with the PicLens option to see the overlaid text in the upper right corner of each image). Another option is to use an image management tool like f-Spot or similar. Many of these offer builtin options to do exactly what you're asking, though they may not be as flexible in how they composite the text onto the image as you require. However, if you really do need to update the image itself and you want to program it yourself, you might find it easier to automate this with ImageMagick. The advantage to this option is that it's more scripted from the shell and doesn't require running a UI interface. GIMP can (I believe - I never use it this way) be run without the UI but I'm not sure it's particularly easier to script in this way. That said, you'll get excellent results using the GIMP's plugin API. You'll end up writing a file browser of some kind to select files, specify the input CSV file and then have the plugin open, edit and save the files all without actually displaying them (to save time).

You can now find those by looking under Windows-Dockable Dialogs, where you'll find separate menu entries for Channels and Layers. Also, the tiny little button the author mentions under Add Some Color section does'nt seem to be available to me for my version. That button is still there but it's more to the left side of the dialog than in the version shown in the tutorial you reference. In 2.6 the Keep Transparency button is labeled Lock: in the Layers dialog. Next to this is a button that, when clicked, shows a check mark. Next to that is a small square that represents transparency (checkered gray squares). The small square is just there to tell you that those items are for Keeping Transparency for the currently active layer. Many people get lost looking for that button. I find it to be one of the harder items to identify when writing tutorials. One more at: http://gimp-tutorials.net/outlinetext I got lost at Step 6, because Alpha to Selection is grayed out and thus I cannot select it. If it's grayed out then that means the currently active layer does not have any transparency in it. Make sure the layer that has transparent areas is the active layer. Also, right clicking to get to this menu may cause the menu's context to be the visible layer at the point of the mouse click. So if you click on the canvas window over the white background instead of the red text you may be attempting to apply the alpha to selection to the background. Confusing, I know, but it's a nice shortcut when you get familiar with using GIMP. IMHO, tutorials should be written using menu options and specific dialogs and should not reference the right mouse click for menu trick because that is an advanced method that can cause a lot of confusion. There are lots of advanced tricks with menus, like tearing them off for quick access. If you use those tricks the tutorial should mention that the intended audience is already familiar with basic GIMP usage via menus and dialogs. Maybe I am doing something wrong or maybe I am having bad luck in picking up tutorials that are targeting at a different version of Gimp. More than likely they're just old tutorials or perhaps just not well written. The only real problem with using an old tutorial is finding where features have moved to or been relabeled in the latest release. In the end, however, the features are still there that were there all the way back to version 2.0, plus quite a bit more. It can take some time finding your way around, though.

You can dock many of the dialogs together but you can't currently dock the toolbox with the canvas window(s) with the dock (re: dialog) windows. This is as designed.

Assuming you're reading the size of the image correctly in GIMP, it appears your scan wasn't at that much higher resolution. Note that scanners convert reflected light (analog signals) into pixels (digital signals) and can do this by varying the range of sampling of the light. Sometimes the higher resolution they advertise is actually a function of their software and not of their hardware. Their hardware may not be able to sample at those higher rates. In that case, and if you aren't using their software, you probably won't get the higher ppi resolution. If you are using their software to scan (I haven't read this whole thread but in this case it would mean you're using Windows) then try opening the image in another program and see if it will tell you the pixel size of the image.

Does the game operate on alpha channels values 0 or does it operate if sees *any* alpha channel? If the latter, then you have to make separate textures for the areas that will and won't be affected by game play. If the former then the layer masks should work for you. I have looked in the alpha channel, and there appears to be no actual transparency in those areas, it seems to be solid black. You know, after all these years I can't remember if 0 is transparent or 255 is transparent in the alpha channel. I thought 255 was fully opaque. But my brain is full. I think that bit of info slipped out on the last refill of the tank. Also, I would like to know how to copy the exact alpha channel from one image to another image, without the original alpha channel being changed.

It shouldn't matter that much, however. I wrote the GIMP Effects book on the idea that the location of menu items doesn't matter so much as knowing what those features *DO* and I focused on core features: Levels, Curves, Layers, etc. I purposely tried to avoid filters that might change with the next release since many filters are just convenience options for using one or more of the core features. The idea is to teach a little about what you're doing to the pixels. Where the tools are in menus won't matter if you don't know what to do with them. So the update would just be to point to the new locations of menus, etc. Unfortunately there is a lot of stuff that is reference material in there that needs to be updated too.

Reset the FG/BG colors by typing D in the image window (resets to default colors). Then drag the foreground color (black) into the selection. That adds black to the selected area in the layer mask. The black area is the area that will be transparent in your saved image.

The others get assigned to other processes. Not sure if the gcc compiler provides options for parallelizing operations, which would probably be the only way GIMP would use more than one core at a time. If this is accurate then you *might* actually better off with the faster dual core if you don't run alot of other applications at the same time as GIMP. But the processor probably isn't your bottleneck. What will matter more is lots of really fast memory. GIMP is memory hungry. Having lots of it that is very fast will improve the perceived user experience, especially with very large images that have many layers. Quad-cores tend to support the newer, faster memory better. Dual-cores are typically considered slightly lower end processors for the chip makers and so tend to be paired with slower memory, though that's not a hard and fast rule.

My SLR died a few years ago and I've yet to replace it. * GIMP: May be used for 'serious' work if that means showing a photo on a web page. Otherwise forget it because: Baloney. See previous comment re: magazine covers. I've also designed images printed on clothing and other products. So you'd have to define serious to validate that assertion. However, serious photography may have different needs than other serious graphic design work. Since I'm not a photographer I can't say if that's the case. ** Is has no color management (I don't know what this is); The current version has color management tools. Color management is the ability to map the colors from one device to another. So mapping the colors you got from your digital camera to what you see on your display requires software to make sure they visually match due to the way hardware (cameras and monitors) behave with respect to color. ** Just 8 bit/channel; Still true. They're working toward 16 bits per channel. Lack of 16 bits per channel can be a problem for some users such as the visual effects industry. ** No CMYK. GIMP works in sRGB mode but can convert from other modes to sRGB (via color management). It does not convert to CMYK mode though it can color separate sRGB into CMYK with plugins. To my knowledge (which is limited on the subject) Photoshop does not work in CMYK mode either - it just maps (on the fly) CMYK to sRGB (or similar color model) so it appears to be working in CMYK. GIMP doesn't do that (at least not yet). PS - I have also been advised to use a program such as Aperture (Mac OS X only) or Lightroom (Mac OS X and Microsoft Windows), as that is what a photographer really needs. I'm sure many professional photographers swear by these. Its up to you to decide if the quality of the results warrant the price. The only way to know - for you - is to compare both the commercial apps and the open source alternatives for what you're trying to accomplish. -- Michael J.

I'm no expert about this so my wild-ass guess is that it doesn't ask because there is nothing to do. Consider that the working profile is what a file *HAS* to be converted to or else you can't open it. If the file has an Adobe RGB profile but there is no such working profile the file couldn't be edited unless it was automatically converted, right? So the conversion would be to your Monitor profile. If you had a monitor profile different than the working profile then the Adobe RGB would have to converted to the monitor profile first and then to the working profile to be edited. Since the monitor profile and working profile are the same then there is nothing to ask - you simply get an automatic conversion to sRGB. But again, that's just a wild guess. I've never dug into that part of the code to know what's really going on. Hopefully Sven or one of the developers will correct me here. -- Michael J.
