Re: [Gimp-developer] Upgraded palette-sort.py plugin
I've finished making updates and have attached the latest version to the bugreport https://bugzilla.gnome.org/show_bug.cgi?id=687552 . I'm happy with the current functionality. A screencast explaining the new functionality is available (47 minutes, 4 parts): (in order:) http://youtu.be/_8e5Uvhn6vs http://youtu.be/Nb4mNs-2ARo http://youtu.be/_1UprDMsPlw http://youtu.be/p_NlcsTzmfk The only material not covered in the screencast is the Index and Random 'channels', which were added after making that screencast. They are pretty self-explanatory, but there's a short explanation of them in the description of part 4 of the screencast. On Sun, Nov 4, 2012 at 10:31 PM, David Gowers 00a...@gmail.com wrote: Done.

[Gimp-developer] 'Select all'/Feather causes segfault in histogram code
Hi, Select all, or Feather, causes gimp-2.9 to segfault inside the histogram code. Which of the two it is, varies. A bit of messing around invoking free select tool, Select menu items, or sometimes just Magic Wand will immediately cause a crash. I'm getting the impression that something's tiles get lost (and don't invoke an immediate error condition) at some point prior to the crash, because on occasion when using the free select tool, GIMP suddenly starts acting as if there is no selection, no matter what I do.

Re: [Gimp-developer] What happened to daily digests in Gimp mailing lists?

It's in your subscription options in the mailman web interface. Another problem is that some replies are deleted, separated or not shown to me but is only received by author of the topic. Is it in the reply and reply to all? What you mean is not clear, but, yes, if you happen to hit reply rather than reply to all, then the email goes only to the person you are replying to and not to the mailing list. ___ gimp-developer-list mailing list gimp-developer-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-developer-list

Hello experts,
I am confused by the calls -gimp_linear_gradient and -gimp_radial_gradient

You'll have to ask the author of G'MIC -- those are functions defined
in GMIC, not GIMP.
If I look in ~/.gmic_def.1500, i can find the following code:

Re: [Gimp-developer] Filtering image on parameter change
On Mon, Feb 13, 2012 at 10:40 AM, Grzegorz Karch grzegorz.ka...@gmail.comwrote: Hi, I'm working on a plugin for which I would like to have the image refreshed every time the user changes some parameter in the dialog. That is, instead of viewing changes in the preview window, I wouId like to see them in the working space, just like in the case of Brightness-Contrast filter (or any other in Colors menu). Could you give me any hints on which functions I need to use? Or is there any relevant example? I tried to look into the source code (gimpbrightnesscontrasttool.c, for instance) but I couldn't make head nor tail of it... The tools do that automatically cause they're tools. Plugins don't and more-or-less can't. You'd be better off implementing your plugin as a GEGL op that GIMP can access (I don't recall offhand whether GIMP supports whatever ops are installed minus a blacklist, or just a fixed list of ops.); then you would get this behaviour through the GEGL tool. ___ gimp-developer-list mailing list gimp-developer-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-developer-list
Re: [Gimp-developer] image modes and indications
On Fri, Jan 27, 2012 at 3:30 PM, c55 inator c55ina...@gmail.com wrote: Error messages and warnings in the status bar are incredibly easy to ignore... I would suggest something like pixelmator [screen capture]http://cl.ly/3D16450D2W2k2H2J042I, which displays overlays on the canvas [here shown with keyboard shortcuts, but the same model can be applied to other notifications]. Displaying information with on-canvas pop-ups like this works well in my experience, as they don't waste any screen space while being there when needed. Example of a pop-up used for dimensions http://cl.ly/2N3O141d3u3h1U3M1B40. I'm in favor of this general model. MyPaint has recently got canvas overlays, and they're, so far, used to display zoom level changes. I find them both very readable, noticable, and also non-obtrusive. I think a lot of the instructions and information we currently put in the status bar could be usefully moved to an overlay -- tool usage instructions are a prime example, look at the paths tool for an example of something that'll really benefit hugely; and 'wrong mode' info is something I have to deal with a fair bit, it would also be good there. One other thing is, if we are going to be informing the user that the image mode is wrong, we should offer them a chance to easily correct it. ___ gimp-developer-list mailing list gimp-developer-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-developer-list
