[Gimp-user] Assigning shortcuts for previous/next color in palette + airbrush rate
Just a query to hear the status on this: I know from bugzilla that there are plenty of procedures that we can not yet assign to keyboard shortcuts. I for one would like to be able to control the airbrush's rate and to move to the next or previous color in the current palette with a single keypress. -Regards, Rene Jensen ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
Re: Comic Book retro style dots [Re: [Gimp-user] Camera to Comic Book]
I really like this technique! Besides the mentioned Newsprint filter there's Gimp's own Filters/Artistic/Cartoon which can help a lot with the black parts. Edge detection on a desaturated version of the layer can also help with delineating the contours The link that Jad Madi supplied also referenced the original Photoshop tutorial at http://www.macmerc.com/sections.php?op=viewarticleartid=209page=1 Some of the methods that are used must be done differently in Gimp, but apart from that it's the same moves. Admittedly I can't get my attempts to turn out as nice as theirs. 1) The crosshatching technique in the dark areas is very essential to this. I'm sure real Gimp-wizzes can achieve spectacular results with the GIMPressionist or whatever but I'm a novice at that. .. New layer .. Drag the pattern 'Stripes 48x48' onto the layer .. Filters/Map/Displace: In X and Y displace source menuboxes choose the original layer .. Add layer mask to the layer which should be distorted now (right click on the layer in the layer menu .. Copy original layer (select layer, Ctrl+C) and paste to the mask (left click on mask, Ctrl-X, Ctrl-H) .. Apply Curves to the mask (Layer/Color/Curves). Set the curve to something like this: `\_ or ``|__ 2) He often uses a combination of Photoshop's Threshold (for making something black-white) and a Diffuse filter which does anisotropic filtering. I can only guess what it does as I don't have Photoshop, but I think that Diffuse+anisotropic == Filters/Noise/Spread with a bit of antialiasing to soften up the hard threshold. You should get the same effect by copying the layer to a new image, double the size, applying Spread, downscaling with Cubic interpolation and copying back again. Anybody who knows a better technique? 3) His Filter/Artistic/Poster Edges is somewhat of a riddle to me, especially since he sets Edge Thickness and Edge Intensity to 0. 4) Then comes my biggest problem: He uses Filter/Artistic/Cutout which has it's closest sibling in Gimp's Image/Mode/Indexed (applyed to a copy of the layer - set dithering to None, not Floyd-Steinberg, and a low color count) or perhaps Layers/Colors/Posterize. HOWEVER this renders very noisy borders between color bands. How to simplify the borders is beyond me, unless one does a Filters/Blur/Gaussian Blur first, but is that good? Perhaps use Filters/Noise/Spread a bit to loosen up on the sharp color areas 5) He uses the original layer with blend-mode 'Color' for changing the colors of his posterized layer. I don't think that Gimp and Photoshop uses the same blend-scheme because he recommends changing both the saturation and lightness of the color-layer for cartoonish style. Nothing happens in Gimp when I change the layers saturation. But making a second layer with mode set to 'Saturate' does somewhat the same. That's what I can think of right know..

If you want an effect like that seen in the Rhino picture you need to learn about Halftones, which is very much retro comic book style as opposed to some of the other simplrer more straighforward Cartoon effects like: Filters, Artistic, Cartoon... The wikipedia page isn't a bad place to start if you want to learn more about Halftones: http://en.wikipedia.org/wiki/Halftone There is also a plugin for the gimp that can achieve this effect but it was confusingly called Newsprint. The Newsprint plugin failed to mention the term Halftone in the short description so even when I knew what I was looking for it still took me ages to actually find the gimp version. http://bugzilla.gnome.org/show_bug.cgi?id=301201 Thanks to Michael Natter the next version of the gimp Plugin Browser has a more flexible search tool which will hopefully make things easier to find in future but I still think the Newsprint plugin could benefit from an overhaul/rename/improved documentation.

Re: [Gimp-user] A couple of game oriented plug-ins
Hi there! Thanks for trying out, and do keep the comments coming. Hi, I installed your plugin but I wasn't able to select brushes. I noticed that the names of brushes starts with OGM so I changed this line in your plugins: self.config[self.name+'-brush' ], 'CGT.*' ) into self.config[self.name+'-brush' ], 'OMG.*' ) and now works better :) That's odd? I renamed the tools from 'Brainsuck O.M.G.' to 'Camilla's Game Tools' in the last minute (guess nobody will blame me), and I've just tested that in the archives I've uploaded, everything starts with CGT..? I don't know, perhaps a stale version of the webpage and package file in some web cache somewhere? Try refreshing. Oh, and do clean all the OMG stuff out to avoid duplicates :) I need to clean up the archives. This page will always be the most recently updated when it comes to CGT: http://www.artcamilla.dk/vaultage/articles/the6502s/articles-gimp/camilla-game-tools/article.html A second issue is that load and save button seem to do nothing :( Sorry, they haven't been implemented yet. Give me a week or two. The settings are saved with your image. Loading and saving is just for making templates so you can transfer a setup from one image/layer to another. A third one is that Gimp crashes when I click on two of your brushes in brushes window. The brushes are OGM GV500 Rim 001 Rivets (8x8) and Rock 004 (that is the same of the first). Sorry about the duplicate :) Yes, I think this is a bug in GIMP actually. You have to click and release fast, or else it tries to display the brush, perhaps as an animation. It seems like GIMP has a problem displaying very small animated brushes. I'll scan for a bugreport and if none mentions this, I'll post one. For now I'm only playing with your plugins but they seem really useful. Thanks a lot, J Have fun. They will stabilize soon :) ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] Sharing code between python plug-ins
Is there a way to share code between python-plugins? A file with common classes and functions would greatly reduce work-overhead for me. It would appear that the usual trick (i.e. from mycommonfile import *) doesn't work as the python interpreter is based at the user home dir (i.e. calling os.getcwd() returns '/home/username' or whatever). That makes it a bit of a problem to import a file placed at /home/username/.gimp-2.2/plug-ins, I think. Any help appreciated.

Re: [Gimp-user] A couple of game oriented plug-ins
Dude, you're right! Thanks! I forgot that I changed my local files in the gimp dir and nowhere else. Well roared, maestro! New package fixed and uploaded at http://www.artcamilla.dk/vaultage/cornucopia/gimp-cgt-v0.1-20050526.tgz -Rene Jensen I'm not sure I understand your answer (english is not my native language) so I try do describe better the problem. Brushes have two names: filename like other files and brushname, that is the name that appears in the brushes dialog. When the script searches for CGT.* brushes it looks at the brushname. Filenames of brushes in you archive starts with CGT, instead their brushname starts with OMG, so IMHO I think is necessary to modify script or brushname. A second issue is that load and save button seem to do nothing :( Sorry, they haven't been implemented yet. Give me a week or two. The settings are saved with your image.

[Gimp-user] Layer Style python plugin..
I'm surprised nobody has hacked on that before. After all, it's all there: Parasites that gets saved with the image/layer, a python module that can update the editor-view live, a complete scripting language with gtk bindings. I spend a handful of hours trying to make a proof-of-concept. See what you think.. http://www.artcamilla.dk/vaultage/cornucopia/gimp-plugins/layer-style.py 1) Make a test image with a background and a transparent layer with say a filled small rectangle. 2) Python-fu / Alchemy / Layer Style 3) Drag the slider 4) Close the dialog 5) Save the image and close it 6) Reopen the image 7) Select either the original gizmo layer or the auto-generated style layer 8) Invoke Python-fu / Alchemy / Layer Style again and play with the slider. There's a HUGE TODO list on that script, but the necessary basics are proven available although IT IS SLOW! But there are room for optimization, especially with a little help from the real pros who knows what is fast and what is slow.

[Gimp-user] Tricks and tutorials
Hmm. Due to selective demand, I've begun to assemble a few articles, tutorials and tips on how to use the aforementioned brushes, patterns etc. but also on various other subjects.

Re: [Gimp-user] Re: Yet another collection of brushes and patterns..
Where exactly do i put the .py scripts so graciously shared? I have tried several different locations ( ~/.gimp/scripts ~/.gimp/plug-ins ~/.gimp/modules) but i cant seem to find the plugin anywhere. The source (if i read it right) should end up under /Python-fu/Alchemy But all i have there is Clothify... I don't understand this? My files are in: brushes == .gimp-2.2/brushes patterns == .gimp-2.2/patterns python scripts == .gimp-2.2/plug-ins and the scripts appear under (when right-clicking on an open image, not in the generic python menu): Python-fu/Alchemy/Brushpipe-curve/rotate-layers I think i have the brushes allright.. Havent tried the patterns or textures yet (Still working out where to put them) The textures are not meant for GIMP but for 3D programs. Actually the patterns are [possibly scaled-down] copies of the textures.

Re: [Gimp-user] Yet another collection of brushes and patterns..
anything they want is the reason to choose a license. While I can't put google on it, somewhere I've read about software that wasn't protected by the GPL. Later, there was a problem proving that it was indeed free software. Putting your code under the GPL license allows anyone to use the code, but doesn't let them place restrictions on its distribution. I've added a Creative Commons license. If you need any further privileges to add brushes and patterns to the native GIMP resource set (if the developers are interested in that) then just say so. Thank for your help btw.

[Gimp-user] Yet another collection of brushes and patterns..
Howdy folks, and thanks for a great program. I don't know where you keep you link section for external resources, but if you want to add my brushes and patterns, feel free to do so. All is free and homemade so no strings attached. I use most of it for game graphics, and it works sweet. One do have to figure out how to use them first, though :) I add to the collection every now and then.
