Created attachment 50528 [details] settings When painting with the hairy brush, if you select one of the predefined brush tips you get very interesting results: it seems as if the tip is deformed, painted four times and with lots of color variation. See attachment
Confirmed! The problem is that KisBrush provides image() and hairy brush uses directly that image. It is called preview but it is not preview for e.g. gbr brushes where it is used as base for the mip-mapping levels. It is not scaled and also the pixel format might be different that the code expects. It will be fixed by rendering the status of the brush into paint device and then the shape of the hairy brush will be taken from the rendered image.
SVN commit 1173087 by lukast: Fix painting with predefinded brushes. Speedup in range 1.15 - 1.30, tested with benchmarks. o Now it renders the dab and takes the bristles from it instead of using preview image. o use const reference to avoid copying the QVector BUG:247835 M +0 -1 CMakeLists.txt D brush_shape.cpp D brush_shape.h M +40 -23 hairy_brush.cpp M +5 -7 hairy_brush.h M +17 -44 kis_hairy_paintop.cpp M +1 -3 kis_hairy_paintop.h M +1 -1 trajectory.cpp M +2 -2 trajectory.h WebSVN link: http://websvn.kde.org/?view=rev&revision=1173087
