Grab the latest ImageMagick 6.9.1-5 Beta. This works for our various compositing unit tests but will it resolve some or all of the problems you are having? Over-blending is enabled and required otherwise we get black lines around graphic primitives such as circles and when we render text.

Tried 6.9.1-5 beta 20150603-20150607, no change since 6.9.1-4. Drawing text or using Arc etc still produces jagged edges on transparent background.

EDIT: also on solid background, that didn't happen earlier.

We reviewed the code carefully and fired upwards of 20 unit tests @ the compositing and drawing components of ImageMagick and they all return expected results. Unless you can provide a command-line or short C or C++ program we can use to reproduce the problem, we will be unable to resolve this issue.

6.9.2-0 now has proper text/draw if black background, but without it I still get problems ... At least there are some progress
