IM 7.0.8-36 "-virtual-pixel mirror" broken

Post by GeeMack »

ImageMagick 7.0.8-36 Q16 x64 HDRI on Windows 10.

This command produces no output image, no warnings, and no errors...

Code: Select all

magick wizard: -virtual-pixel mirror ^
   -distort affine "0,640 0,640  480,640 480,640  0,0 480,0" wizard.png
Changing the virtual-pixel setting to anything other than "mirror" produces expected results.

On my Mac with IM 7.0.8.36 Q16, I get an abort trap for mirror and tile and its variant, but not for edge or random or dither or black.

Code: Select all

magick wizard: -virtual-pixel mirror -distort affine "0,640 0,640  480,640 480,640  0,0 480,0" wizard.png
Abort trap: 6
