I think you are right in pointing out that not all 'painting' actions (like heal or dodge and burn, or just subtle painting) give strong enough results that can 'speak for themselves.' trying that out myself with heal, dodge and burn and the round fuzzy brush, I found the outline also utterly useless at showing me what was going to change how strongly within that outline. nice pair of opposing requirements during painting: 1) give a clear and exact impression of the effective brush, including its fuzziness, no matter what's on the canvas 2) get out of the way of very subtle 'painting' results --ps founder + principal interaction architect man + machine interface works http://mmiworks.net/blog : on interaction architecture ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

This can be taken to the extreme by setting 'idle' opacity to 100%. But then this only makes sense for drawing in normal mode on the top layer. And becomes totally useless for the dodge/burn tool. Adding contrast needs some thought -- at least the standard XOR 0x7FFF7F doesn't perform well using simple blending according to brush stamp alpha: http://yahvuu.wordpress.com/2009/08/30/scratch-trash/ somebody got ideas for better algorithms? > - that really opens up what (dynamic) paint parameters should be > reflected by the brush when not painting: looks like brush geometry > (brush, scale, aspect ratio, angle) yes, hardness: maybe, rest > (opacity, spacing, jitter, color(gradient)) no. i'd love to indicate hardness somehow.

As a tablet user, the above is exactly what I want; I certainly don't want an outline while painting (may not be completely accurate, and I tend to move too fast for the outline to have any real use) When using a mouse, visual response to movement tends to be predictable enough that I don't really gain anything from the brush outline during painting either. +1 on crosshairs-only during painting ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Peter- To clarify, you are suggesting the on screen pointer icon/sprite could show the actual brush as it would look painted with a single mouse click, but once painting/holding the mouse down it would render as a cross hair?

what about printing a semi transparent copy of the actual brush on the canvas? Is it possible? The "ghosted" brush can have two opacities, one for the preview when the tool isn't in use, and one more transparent when the tool is in use. I wouldn't mind to have a simple circle of the size of the brush as the default mode and an alternative option for overlaying a semi-transparent brush image. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Hello Martin, once i suggested at GIMP brainstorm painting two lines for fuzzy brushes and feather borders. One dotted where pacity = 100% and on with just any secound dot where opacity = 0%. A center mark would be great too. So artists know where is the center of the stroke (may for connecting border or painting along a line) and where is 100% color and where is it faded out. This border feature would be great for feather borders too (without center mark of course).

One of the reasons for this is that hardness (which creates the fuzzyness) is a brush attribute which can dynamically change with brush dynamics (in static conditions hardness could be 100% hard, but become completely fuzzy as drawing pressure increases for example), and would better work with my proposal of varying in realtime brush outlines according to them. -- SHIRAKAWA Akira ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

One more thing that has always irritated me (not related to your change
though): The lower-left -> upper right lines ("/") seem to use a different
corner case of the same algorithm (looks like a different algorithm even) as
compared to the other side ("\").
Other than that I think it makes sense to show not the total affected area but
only the area which is affected by more than a certain nonzero threshold (say
opacity >= 20%).

Hi all, My opinion about that is the same as shirakawa if we want to do photography retouch and "superexact" works like these, but artisticaly i would prefer something like Martin says. It is more useful for the eye, if we want to make an stroke fast and not acuratly but in the aprox right place.the old method requieres user imagination to preview in his mind what will happen... but i have to say that i don´t use this "brush outline feature" becouse it makes my gimp sloower with complex outlines.So if somebody has the solution for this... i am listening. best regards 2009/8/30 SHIRAKAWA Akira > Martin Nordholts wrote: > > > I think the current brush outline for fuzzy brushes is too big.

In my opinion the idea of the brush outline is that it represents its total area of effect, or in other words, the area where pixels will be affected in a way or another while drawing. The brush outline for fuzzy brushes (assuming dynamics aren't applied) *looks* too big, but it actually isn't. This is most evident by drawing a few strokes with the fuzzy brush on a transparent layer and then adjusting the alpha level channel on Colors>Levels to coordinates (0;255) . A more useful patch (in my opinion) for brush outlines would be making them change together with brush dynamics (even if the user isn't actually drawing, just moving the cursor on the drawing area) if they are enabled. This could be useful in many ways, but I have the impression it would lead to performance issues. -- SHIRAKAWA Akira ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
