[Gimp-user] Digital Watercolor effect in GIMP?
When reading about Corel Painter, I've frequently come across a so-called Digital Watercolor effect, which apparently simulates how wet paint behaves when you apply color to a canvas - the virtual pigments are gradually diffused across the surface of the paper and then absorbed into it over time. This sounded pretty fascinating, and I was wondering if anyone has attempted to create the same effect with GIMP. Or would it require too radical a rewrite of the code? After all, currently GIMP assumes that it doesn't matter _when_ you make a certain stroke with the virtual pen; it doesn't matter if you do a certain stroke two seconds or two minutes after the previous one - the result will be the same. But to implement such an effect, some kind of time-sensitive mechanism would have to be included - or at least, that's my impression from reading about it... - Jürgen Hubert The Art Tutorials Wiki - catering to everything an artists needs to know! http://artwiki.wikidot.com ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] GIMP on Mac OX X Leopard
Does anyone know if it is possible to compile GIMP (MacPorts) on Leopard (PPC)? I've tried, but I am getting errors during that process... Thanks, Victor Domingos ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

You may want to take a look at Wetdream by Raph Levien: http://www.levien.com/gimp/wetdream.html As far as I know, it's still not in GIMP, but the author explains quickly some of the integration problems, because of the difference in the way pixels are stored. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] Trouble calling running batch script in Windows XP
I do not believe that single-quoting a command line argument in Windows works the same as BASH (Linux). Try using double-quotes and escape any double-quotes which appear in your argument: gimp -i -b (batch-CUPify \*.png\) -b (gimp-quit 0) If you include directories in your path, also escape your backslashes: gimp -i -b (batch-CUPify \D:\\Documents and Settings\\spk30\\Desktop\\alison_sl1_dear_friend_backup\\*.png\) -b (gimp-quit 0) You may need to experiment as I do not run Windows and have no way of testing the commands. I am using GIMP 2.4.1 on Windows XP, and I am trying to run the script by going to the command prompt, changing to a directory full of .png files I want to process with the script, and entering the command: gimp-2.4 -i -b '(batch-CUPify *.png)' '(gimp-quit 0)' This gives me the following messages: GIMP-Error: Opening 'D:\Documents and Settings\spk30\Desktop\alison_sl1_dear_fri end_backup\*.png)'' failed: Invalid argument GIMP-Error: Opening 'D:\Documents and Settings\spk30\Desktop\alison_sl1_dear_fri end_backup\'(gimp-quit' failed: No such file or directory GIMP-Error: Opening 'D:\Documents and Settings\spk30\Desktop\alison_sl1_dear_fri end_backup\0)'' failed: No such file or directory No batch interpreter specified, using the default 'plug-in-script-fu-eval'. batch command: executed successfully. I would be very grateful for any help you can offer.

Hmmm. That page is dated to September 4th 2001, which isn't encouraging.

If you have this great concept of a script-callable api, it seems tantalizingly close to use the api from a script recorder, too. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

The UI has to be refactored to use that API as well, which is 80% of the work. It's a large job, and none of the code in bug even touches upon that. You also have to solve the problem of translating tool mouse movements into API calls efficiently. It's pretty rude to imply that something is easy when you haven't even taken the time to actually think through how much work is involved. -Yosh ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
