[Gimp-user] palette mapping
Hi all. I'm new to the list. I have joined because I need help. I'm making a gimp-python scipt to create cross stitch patterns from an image. Reading list's archives i've founded this http://www.mail-archive.com/[EMAIL PROTECTED]/msg01127.html I don't know if Carol has completed his idea. By now, i'm evaluating how much work can make gimp by itself. The feature that i can't find in gimp is to map an image with a custom palette (DMC Floss colors). Gimp only allows me to convert from RGB to Indexed mode, but it doesn't allow to choose a custom pallete with more than 256 colours, and doesn't allow to choose the maximum number of colours. Any help? Thanks in advance ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

[Gimp-user] Gimp-print border
I am using gimp 2.0.4 with gimp-print 4.2. Mandrake 10.1 with an hpdeskjet 5550. Off and on for the past year I have tried to figure out how to change the default margins in gimp-print. I have searched, googled read the archives and have not found a way to change the default margins. I particulary find the .5 left margin troublesome. I have the latest HP driver installed. I hope there is an easy solution. I have lots of pictures with uneven borders. Thanks Gary ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
Re: [Gimp-user] palette mapping
Hi Fernando! I am even working on a script to do this these days, - map a palette to an image based on value information (not nearest color - as the GIMP does, but buy color value: black is mapped to first color in palette and so on). Unfortunattely, the GIMP can only handle indexed images with 256 colors. My script _can_ map a palette to an RGB image, but currently, as I said, I am using the pixel Value to do that - and there are only 256 color values allowed in 8bit RGB . :-(. For Value here I mean the Pixl Value in HSV color model, which is MAX (R,G,B) Moreover, I use a trick with the the GIMP curves tool to do that, aand the curves tool will also only use 256 colors. How many colors do you need? if less then 512, I can think of a trick whicth I could tune my script to do automatically - using another component besides pixel Value - possibly the Red channel - to have more than 256 target colors. This would map, again, in palette order. If you want the nearest color, the better thing to do is to get yourself a Patch to the gimp core, in which an image is mapped to a palette, but remains RGB, using the same algorithims thgat are there already. I think I could provide sucha a patch, that would hardly make it into the official GIMP. It would be a thing for your use only, at least for a while. That would use some of my work time - so, what I mean, is, how much do you need this? BTW, all my scritps are gimp-python. I will mail you my palette mapping script in private anyway - at least you can study it. Unfortunnately, the GIMP On Sunday 17 October 2004 13:52, Fernando Sancho wrote: Hi all. I'm new to the list.

[Gimp-user] My new Howto on batch color correction using script-fu
Hey all, Maybe someone on this list is interested in this: Here is a new step by step howto on batch color modifications (i.e. getting proper white balance) using GIMP script-fu. http://schweizerhof.docbryner.com/~marcus/slidestodigital/howto.html I've been using a slide duplicator to convert 1000's of slides to digital using a Canon A70 camera, then running them through GIMP to correct for proper white balance. I started writing the howto just for myself for future reference, but the project evolved Anyone know other good places to post this where someone might be interested? Let me know if anyone finds this useful! :) Marcus Bryner ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
