brushes again...

GIMPsters,

talking to Alexia today we came up with a matrix of different cases needing different cursor feedback:

in one dimension: mouse up; mouse down + not moving; mouse down + moving

in the other dimension: painting; touching up; textures/image brushes/ stamping

multiplying this 3x3 matrix out we got 9 cases that all need their own feedback (or not) for assessing the
1) centre coordinate
2) outline of brush stamp
3) opacity of stamp pix
4) a fitted ellipse or rectangle that hints at the total brush area, aspect ration and angle.

the goal of this mail is to getting this matrix filled for each case.

share your experience,

--ps

Some drawing/painting/image programs also support indicating the current paint colour in the brush pointer/outline.

Need ... more ... bloat ...

:oP

I for my part would find it absolutly enough if the brush size was indicated, and even that possibly only by a bounding box which is light on resources.

The point is that everything else, color (that would be completely irritating for me), opacity (equally irritating) and shape (hard on resources, as I've been told) is what you know or can see by a quick peek into the according dialog. As a painter with a pen opacity wouldn't help me much but I see that for people who do some exact and careful editing previewing opacity might be useful.

At least for me, only Brushhsize is what I have absolutly no idea about. I can use the same brush for 10 hours and still wont know what size is "10 pixels" - mainly because I just drag the slider and base my adjustments on the current size - make it relative.

Choise 4 of the below seems to be the most eligible to me, though I must admit that this applies only for painting and not photo editing with the mouse.
