[Gimp-developer] Perspective tool - preserve aspect ratio?
I was using the Perspective tool (GIMP 2.6) on some photos to correct for some minor rotation/skew issues, and realized how easy it is to throw the image's aspect ratio out of proportion -- in my case, TOO easy. My photos were of some quilt squares, and I was using the edges of these squares as guides for aligning a Corrective transform to correct for some minor (but visible) skewing. Naturally, this means I'm aligning my Corrective guide to an area in different proportion to the source image, so it throws the aspect ratio out of whack, and I must have the squares in the photo remain square after transformation Is it possible for the tool to compensate for X/Y aspect ratio distortion somehow? Or is that too much to ask? On a semi-related note, how does the Perspective transform matrix work? I get that the first two rows represent an affine transformation, with (1,3) and (2,3) corresponding to X and Y translation, (1,1) and (2,2) corresponding to X and Y scaling. What's the third row represent? - strata_ran...@hotmail.com Numbers may not lie, but neither do they tell the whole truth. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

I've played with 2.7.3 on Windows a little bit. Here are some other ideas for new dynamic outputs: Hue, Saturation, and Value/Luminance Brian Allen Vanderburg II Those can already be simulated using the Color dynamic and careful RGB values, although as mentioned in bug #572300 the current Color dynamic (i.e. low pressure = FG, high pressure = BG) is a bit counter-intuitive in 2.6. -- Stratadrake strata_ran...@hotmail.com Numbers may not lie, but neither do they tell the whole truth. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Dunno about Increment, but Fade is already in the brush dynamics matrix for 2.8. The matrix is currently 7x10, and I strongly suggest the team to consider building and selling a customized version of monome to control it :) Actually I'm probably mistaken on the incremental option -- been a long time since I tried to use it. So what are all the dynamics on the plate for 2.8 anyway (compared to 2.6) ? -- Stratadrake strata_ran...@hotmail.com Numbers may not lie, but neither do they tell the whole truth. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

[Gimp-developer] More Brush dynamics?
I recently discovered I've misplaced my Wacom pen stylus -- the tablet equivalent of losing your car keys. Ouch. Anyway, it gave me an idea for GIMP: Can the Incremental and Fade Out brush options be incorporated into the Brush Dynamics grid? The options basically link opacity to stroke length, but it would be nice if we could link stroke length with other factors like brush hardness or color. (For example, linking color to stroke length would mimic the effect of a simple gradient.) -- Stratadrake strata_ran...@hotmail.com Numbers may not lie, but neither do they tell the whole truth. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
