Good example, because it shows how natural transparent color is. The answer: you should get exactly the same effect if you have blue color and paint on top of semi-transparent red.

Again, it is not a replacement. Honestly, I didn't thought of this issue -- it can be done, but to achieve intuitive behaviour it should be well designed not to change too many things.

You could change the color information at the same places (and less importantly in a single step) you change the alpha information. At least that's how I understand it. Imagine painting with a solvent-diluted color, somehow. It might prove useful, although it might also interfere with current workflows.

A define placed inside another define can only be used locally by code in the enclosing define. What you are probably referring to is how a define that is global to code in one file can conflict with a define in another file if the names are the same. This is due to all script files are read in to a single block of memory used by the interpreter. To avoid the problem, nest defines when you don't need something to be accessible from in another define in a given file. If a define (ie. function) needs to be global so it can be access in multiple define blocks in a file, avoid using generic names that someone else might have used in another file. One way to avoid name collision is the prepending of your initials to your own defines. -- Cheers! Kevin. http://www.ve3syb.ca/ |"What are we going to do today, Borg?"

What should happen if you have a semi-transparent red and you paint on top of blue? Currently it gets blended on top of the blue resulting in some kind of violet and that is a widely used feature to do natural looking paintings. I understand your proposal, that you actually want to have a semi-transparent red in the image after painting? How is your new feature supposed to interact with tablets with varying pressure devices like tablets? Right now you can map the pressure information pretty naturally to the opacity. Your "replacement" approach for alphacolors would directly influence the images alpha channel, making it pretty tricky to lift off the pen without leaving a transparent spot (tablets tend to add some events at the end et the stroke with very low pressure). How is your "replacement" approach supposed to work with multiple layers? I see lots of open questions here and I have doubts that your desired workflow is an improvement over the current one. Also I think that most of the tasks you mention in other mails - like cleaning up edges - can nicely be done with the current gimp, provided that you don't need 100% exact control over the alpha values (like the texture guys seem to need it, but they are not the main target audience). So I still don't see the problem here that needs to be solved.

Why unhelpful? Note, that you are already used to something, and different does not mean unhelpful. I would love to change colors (including transparency) so I could focus only on several tools. For me using alpha channel just to make something transparent is tiresome because I have to use more tools than I really need. > But even taking him into account the current model > has served us well for the last years and there has been very few > discussion about this specific problem, if it cropped up it was in > the context of indexed PNGs with "alphacolors" or generating > textures for renderers.

I don't think that this is a sensible approach in general. We currently use alpha to do proper antialiasing, compositing existing photos on top of each other and in all of these cases a coupled "alphacolor" (= color + alpha value) would be cumbersome and unhelpful. > Such metaphor is more accurate to real world and thus more appealing > to weekend artist (who would like to do some things in simple > manner). Note, that Gimp is not designed with the "weekend artist" in primary focus. But even taking him into account the current model has served us well for the last years and there has been very few discussion about this specific problem, if it cropped up it was in the context of indexed PNGs with "alphacolors" or generating textures for renderers.

[Gimp-developer] [bug] incorrect math: adding/substracting empty selection deselects selection
Hello, I was asked to bring this issue to the ML instead of discussing it on bugzilla so here we go. Original post: http://bugzilla.gnome.org/show_bug.cgi?id=549925 Simple facts from math and Gimp: 0 is empty set A is just a set what is A u 0 ? in Gimp it is 0 what is A \ 0 ? in Gimp it is 0 Such behaviour is even counterintuitive -- if I have selection and I remove one pixel from it I will get previous selection without that pixel. If I don't select anything, selection should be unchanged -- yet, Gimp removes entire selection When I polishing images I am tired over time and Gimp makes me even more tired -- I from time to time just click a mouse (accidentally), or when selecting (adding) one pixel my mouse was moved (one pixel -- irony isn't it) on LMB release, in effect I selected 0 pixel instead of 1, and then I have to undo last operation because I lost my selection. The current behaviour makes perfect sense for setting the selection, but not to adding/substracting. It does not help, quite contrary -- I have to focus more than I should because of the artificial limit of Gimp. When selecting 100x100 pixels you can't spot it, but when selecting one pixel Gimp policy is like "no mistake allowed". And note that I am not handicapped. Kind regards, PS. I believe this mail was not delivered to ML (I checked in the archive for being sure) so I am sending it again. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
