[Gimp-user] To convert grayscale in camera or Gimp
Hi Rick, > if I shot in B&W (via digital camera), wouldn't that give me a better image, > to work with in Gimp, instead of converting it to Grey Scale? For all consumer digital cameras I'm aware of, you'll be caputring in color; the camera will be running an algorithm to convert to grayscale. If it has the option to do both, its pretty much certain that its capturing in color internally. Depending on the sensor and the camera, there may be some theoretical advantages to doing conversion in-camera. If it internally uses 12-bits per channel of resolution (or higher, or algorithms utilizing the RAW characteristics), you may get smoother and more accurate grayscale out the camera than would be possible to accurately get with GIMP (which is only going to work with 8-bits per channel and has no knowledge of your sensor's layout). Of course, the camera could be taking a cheap way out too, and using a lousy algorithm for conversion figuring correctly that 99% of the users would never care. However, you have more control over the subtle differences when using GIMP to do your conversion. For an excellent intro to different techniques to get different results, see http://www.gimpguru.org/Tutorials/Color2BW/ . This also goes into how the smoothness of this histogram (which is important for grayscale) can be adversely affected by colorspace conversions in GIMP, which is a big reason why some people really want a higher-bit-depth GIMP. These techniques also take a lot more time, and are pretty useless unless you have a monitor that is capable of really showing grayscale differences with some accuracy. So at least until Gimp3, it comes down to an argument of (possible) accuracy and speed from the camera, vs artistry and care with the Gimp. They've both got their points going for them. What makes a "better" image is not so easily answered, and may not even be an issue for you depending on your desires.

[Gimp-user] Magic Background Eraser
I've been playing with PS Elements (came with my camera) so I recently found it and played with the background erase tool. Its a fixed aspect brush (only a circle, though you can vary its size). It samples the current circle continously, and uses its average (center weighted I think) to determine what the current "color" is for a color-to-alpha type removal. There's a threshold parameter which determines how close something has to be to get the color-to-alpha treatment. With a bad threshold, the tool is pretty unusable (becomes either like a bad eraser, or a paintbrush in color to alpha mode). I find I have to change it a lot, even on the same image. There's also a Continuous or Discontinous paramterer, but I'm not able to determine what this does simply by playing. A typical usage pattern is to trace around the outside of an object you want to cut out, just barely touching the object with the outside of the brush (the idea is that this will stay out of the threshold and remove everything else). Its not a smooth drawing tool - the outside generally looks like a bunch of semi-circles (I think it requires having a center pixel non-alpha). However, the inside will hopefully be fairly representitive of the outline of the object. It also suffers from the same problem as color to alhpa, in that it tends to leave garbage around (with a low alpha) that you have to go back and touch up later. JPEG noise is especially prevalent, so its best to run a noise filter over it before doing this. If we want to make a killer tool for background erasing, we should really be looking at knock-out or an equivalent, but the background erase tool isn't bad for quick removal (and certainly is more applicable than something like color-to-alpha in a typical real-photograph situation). Hope this helps! Seth Burgess [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

[Gimp-user] removing background
Nikolai, >How can I do with gimp to remove the purple color fully and convert the >borders where the object is merging with the background into pixels that has >Alpha values over yellow color instead of plain orange color ? Very nice description of a classic imaging problem. Luckily, this is precisely what the color to alpha plug-in was designed to handle. Filters | Color | Color To Alpha, select your purple color, let it run, and wholah· The major drawback is that it doesn't only operate on "border" pixels - it operates on every single pixel in the image (or current selection). This means: 1) If you have a real life background like from a photo, you probably don't have a solid color to remove 2) If your foreground has any component of the color you're trying to remove, that will be removed too. #2 is worked around by repainting "under" the image with the same color you just removed. For #1... you can keep selecting colors that don't get hit and re-running it, but my suggestion is to get it close and do the rest of the touchup by hand.

[Gimp-user] Re: Gimp-user digest, Vol 1 #312 - 1 msg
Hi Tom, This is probably a question better asked in the gimp-devel list. As far as status as far as separation that would allow a KDE gui to be written, let me give what I think I know :) There's different levels of completeness here. Much of the code now just depends on glib (no gtk+). The GUI code is becoming more and more separated. Its off in its own directories now. For this portion of the code, it would just take someone motivated to write the KDE (qt) front end. Also, plug-ins have always been pretty separated. However, some things we know still have an interdependance. Tools are one of those things (unless something changed when I wasn't looking). They'd probably need some rewriting to enable another toolkit. Tool code has traditionally been some of the less easy-to-grasp code in there (tile code notwithstanding), but thats getting far better too. Gimp-Perl wouldn't work terribly well, and there's probably others I'm not thinking off that would break as well. Really the plan for having an independant library you can write your own front end for is the 2.0 GIMP release. 1.4 will be moving in that direction, and we do have a number of libraries now, but probably won't reach it. 1.4's release (if history serves) is probably a year or 2 out. 2.0 is still a way off. And of course this depends on a KDE hacker wanting to do something with it. A long time ago, there was some ugly fighting between gnome and kde people over gimp, which if I recall correctly left a bad taste in KDE's mouth for using any of GIMP's source. I've not checked on Krayon's progress recently, but they opted for that choice back a long time ago (called KImageShop then). KDE folk may reconsider, who knows.

Hi Jim, Use Filters/Colors/Color To Alpha Select the background color. This will convert all the background to alpha, and leave the dithered foreground.

Re: [Gimp-user] creating new brush?
Subba, I'd agree with Rebecca here. What you're trying to do sounds a lot like a clone operation. To use the clone tool, select your "source" by holding Control, and clicking where to start copying from. Then release Control, and paint into the "destination". All of this uses the current brush shape do to the painting. If you really want to make a new brush (it doesn't sound like it from your description) you can always save as a .gpb (gimp pixmap brush) into your ~/.gimp-1.2/brushes directory, refresh the brushes, and select your new brush.

There should probably be some explanation somewhere of what built-in types gimp expects.

Re: [Gimp-user] beginning with The Gimp
Hi Eric, You probably don't want to use Gimp for this task - instead look at ImageMagick. Specifically the convert utility will do what you're wanting far better than gimp, with less memory and far less headache. Scripting in general is a domain for a power-user of gimp, and batch mode is even worse. Unless you have to do something only present in gimp, I'd suggest using other tools for this.

Re: [Gimp-user] Palette / Index Covert Question
Unfortunately gimp doesn't have an indexed mode that supports more than 256 colors (yet). In general, the indexed mode is rather neglected in gimp. There may be a plug-in to leave it RGB and reduce the number of colors used, but I'm not sure what its name would be.

Re: [Gimp-user] Selections & Transparency
Josh, Sounds like what you want is my colortoalpha plug in, that is distributed with 1.2.x. I think its under Filters/Color/Color To Alpha... Just select white and click OK.

Re: [Gimp-user] transparency with png
There's a couple of scripts that take a background color (or layer) and make a thin halo around your transparent image. This won't make a smooth gradient, but if you have some idea what your background is going to be it looks great. Even against a patterned background the human eye is quite forgiving. The 2 I know offhand (I wrote one) are prep4gif and alphaGif.

Re: [Gimp-user] gradient
Jeff, I suspect Indira was referring to the results (the gradients). These you place in your ~/.gimp-1.2/gradients/ directory for an individual user, or in your /usr/local/share/gimp/gradients/ directory for system-wide access. (both these are defaults for 1.2 on a unix-like OS - if you installed differently, your directions will vary). Also, would you mind if I converted those scripts into gimp-perl scripts callable from within gimp? They seem pretty useful!
