[Resolved] possible bug clip path IM 7.0.5.5 Q16
Posted: 2017-05-12T15:13:17-07:00
I can apply a clip path to the following image in IM 6.9.8.4 Q16 fine. But when I use IM 7.0.5.5 Q16, it seems the clip path is inverted and masks the inside rather than the outside.
Input:
http://www.fmwconcepts.com/misc_tests/c ... OV_EPS.eps
IM 6.9.8.3 (works fine):
IM 7.0.5.5 (fails):
So I thought I could capture the alpha channel and negate it and re-apply to the png. But this direct method fails also with a totally transparent result.
However, oddly, if I do the same first part and save to miff: and pipe to a new second command line, it works fine. Why is that?
