[Gimp-user] Script Problem
Hi, I've got a bit of a problem with a script that I make fairly extensive use of to create buttons for websites. It started out life as a GIMP-1.1 script and I upgraded it to work with GIMP-2.0 but have recently upgraded again to GIMP-2.2. Unfortunately this has broken the script (right when I need it of curse) and I can't figure out what is wrong. The offending section is below with a comment above the first line that breaks. According to the PDB gimp-edit-fill requires a drawable and an int32 which I think I am giving it but it just dies with Procedural database execution failed. Any ideas? If you want to see the full script it is hosted here: http://www.crazysquirrel.com/software/gimp/aqua_gimp_2_0.scm If I can fix this I will of course make a new version of the script available. Many Thanks --- (if (eqv? shadow TRUE) (begin (set! shadow1-layer (car (gimp-layer-new img width-all height-all 1 Shadow Layer1 100 SCREEN))) (set! shadow2-layer (car (gimp-layer-new img width-all height-all 1 Shadow Layer2 100 NORMAL))) (gimp-image-add-layer img shadow2-layer -1) (gimp-image-add-layer img shadow1-layer -1) (gimp-drawable-fill shadow2-layer TRANS-IMAGE-FILL) (gimp-drawable-fill shadow1-layer TRANS-IMAGE-FILL) (round-select img shiftx shifty width height ratio) (gimp-selection-shrink img (* height 0.1)) ;This is where it breaks first (gimp-edit-fill shadow1-layer FG-IMAGE-FILL) (gimp-hue-saturation shadow1-layer 0 0 75 0) (gimp-selection-grow img (+ 1 (* bluramount 0.3))) (plug-in-gauss-iir2 1 img shadow1-layer (+ 1 (* bluramount 0.3)) (+ 1 (* bluramount 0.3))) (gimp-drawable-offset shadow1-layer 0 1 0 (* height 0.4)) (gimp-selection-none img) (round-select img shiftx shifty width height ratio) (gimp-edit-fill shadow2-layer FG-IMAGE-FILL) (gimp-hue-saturation shadow2-layer 0 0 0 -25) (gimp-selection-grow img (+ 1 (* bluramount 0.3))) (plug-in-gauss-iir2 1 img shadow2-layer (+ 1 (* bluramount 0.3)) (+ 1 (* bluramount 0.3))) (gimp-drawable-offset shadow2-layer 0 1 0 (* height 0.4)) (gimp-selection-none img) )) ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
RE: [Gimp-user] Color Reduction with GIMP
This method does not deliver what I require. But thank you for helping me learn how to manage palette's. What I need through GIMP is a way to remove individual colours from the image dynamically in real-time. For example, I would click one colour to turn it off and see the change to the image. If the image isn't severely affected by turning off that one colour, then that colour should be removed. I deal with images that are only 2-64 colours each, and shaving off colours is a huge importance to get the filesize down to the absolute smallest. Currently I use Web Image Guru to do this. Great program. But it costs money. The programmers I work with are all interested in installed GIMP on their machines. So going through GIMP, I haven't been able to easily reduce colours of an image on-the-fly.

It doesn't allow you to remove colors, but you can change palette entries of the active colormap on the fly, and after all redundant colors are set to be equal to another existing color, just do the mode-rgb, mode-indexed thing.

RE: [Gimp-user] Color Reduction with GIMP
Once a colour would be removed from the palette, the pixels in the image should change to the closest matching colour in the palette. There would be an algorithm that chooses the replacement colour. If you have seen Photoshop or Image Ready's Save For Web feature, you have seen this. You are presented with not only a colour limited (Choose a number between 1 and 256), but it displays the entire colour palette and you able to manually select colours to LOCK or REMOVE from the palette, and you can see the preview of the palette changes on the image before you save. There's an image browser and batch processor called Web Image Guru by Vimas that does this task most excellently. This is what I use on a day to day basis. But it isn't a free tool like GIMP is. The other people I work with are very interested in using GIMP for all our imaging needs... and it does almost everything... except for good colour reduction. -Original Message- From: Andreas Waechter [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 22, 2005 12:18 PM To: Kalle Ounapuu Subject: Re: [Gimp-user] Color Reduction with GIMP What I need through GIMP is a way to remove individual colours from the image dynamically in real-time.

What should happen with the pixels that have the color you want to remove? Should they go transparent? If so, select by color with threshold set to zero, then clear selection. Should they be replaced by another color? If so, select by color with threshold set to zero, then fill selection with the other color. Or should something else happen to those pixels? If so, what?

Hi, Michele Petrazzo [EMAIL PROTECTED] writes: Did you use the default value for the tile cache size, or did you adjust it? The default value is 128 MB IIRC, but if you're going to open large images and you have 1 GB of RAM, it should be much higher than that. On linux machine I found only maximum size of new image Look again then; it's in the Environment preferences page. And GIMP did also explain this setting to you when it run the user installation.

[Gimp-user] Dragging (moving) a selection
Hi :) I've just started using GIMP in Linux and I've come to a problem. I suppose the answer is simple but I've looked and tried everything that came to my mind... Let's say I make a rectangular selection but it turns out it doesn't exactly select the area it was supposed to. So I would like to drag (move) the selection (and only selection, not the part of image that is selected) to some other place. In Windows I would press the Alt key and drag with my right mouse button but In Linux I cannot - instead of the selection I'm moving the entire GIMP window! :-O So is there a way I can move the selection and not the part of image it select, nor the window?

Sure, two ways even: (1) Reconfigure your window manager to not use the Alt key (you could for example let it use the Windows key, provided your keyboard has one). (2) Press Shift together with Alt.

Hi, Graham Smith [EMAIL PROTECTED] writes: --pdb-compat-mode on : made no difference It shouldn't since that's the default. But I wanted to make sure. I also checked the code and the old enums are always available. The command-line option only affects deprecated function names. --pdb-compat-mode warn : produced the following error messages on stdout These warnings indicate that you should port your code to the new context API. It will continue to work with the old API but the new stuff has some advantages. You can call gimp-context-push / gimp-context-pop around your script and have it run in it's own context, thus not affecting the foreground/background colors in the user context. Using the constant the PDB seems to recommend GIMP-FOREGROUND-FILL results in an unbound variable error being displayed. Why does FOREGROUND-FILL work and GIMP-FOREGROUND-FILL fail? Is that a mistake in the PDB or should I just know to knock GIMP- off the front of the name? You are supposed to know. The Procedure Browser and the API docs show the C API. The Script-Fu API uses slightly different style. Sven ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Unfortunately this has broken the script (right when I need it of curse) and I can't figure out what is wrong. The main problem is that you didn't sent us the full script and due to the bad indentation it's rather difficult to see the problem. You are most probably calling gimp-edit-fill on a drawable that has not yet been added to the image. This has always been wrong and won't work any longer in GIMP 2.2.

[Gimp-user] Opening Geo-Tiff files in GIMP
I'm a new user, trying out GIMP. I have a requirement to edit some files in geotiff format. When I open the file, I get an alert dialog about unrecognized tags (which is OK as long as the data in them are preserved) but these files are in 8,8,8 color and when GIMP loads them, they are in 8 bit greyscale. So far I have been unsuccessful in figuring out why the 3 layers aren't being preserved.
