From f622691691547bb364fe6a560124583030d55c11 Mon Sep 17 00:00:00 2001 From: Antony Riakiotakis Date: Fri, 9 May 2014 23:29:57 +0300 Subject: Fix access violation when painting with tiled textured brushes + airbrush + small brush size. Fast textured strokes meant that sometimes the update width (calculated from stroke distance) would be greater than the new ibuf width. This meant out of bounds access for the new ibuf. It's totally strange that I couldn't reproduce this issue on older versions since the logic here has not really changed much between versions. --- source/blender/editors/sculpt_paint/paint_image_2d.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/source/blender/editors/sculpt_paint/paint_image_2d.c b/source/blender/editors/sculpt_paint/paint_image_2d.c index 16dacaebfb1..667b487d4b1 100644 --- a/source/blender/editors/sculpt_paint/paint_image_2d.c +++ b/source/blender/editors/sculpt_paint/paint_image_2d.c @@ -491,8 +491,8 @@ static void brush_painter_imbuf_partial_update(BrushPainter *painter, const floa w = h = 0; } - x1 = destx; - y1 = desty; + x1 = min_ii(destx, ibuf->x); + y1 = min_ii(desty, ibuf->y); x2 = min_ii(destx + w, ibuf->x); y2 = min_ii(desty + h, ibuf->y); -- cgit v1.2.3
