We need a URL to in.jpg so we can download it and reproduce the problem. Thanks.

We're using ImageMagick 6.9.0-7. It returns similar results for your image and command as ImageMagick 6.8.9-6:
  • compare -metric rmse test-6.9.0-7.png test-6.8.9-6.png null:
    8.43308 (0.00012868)
If you still feel there is a difference, post an (x,y) position of the pixel or pixels that you think are wrong. We'll investigate further.

If you look at the bottom of the image in the shadow there is a darker area.

It is the corner that has been left after the distort and filled with -virtual-pixel transparent.

Have you tried with 6.9.0-7? We're not getting the darker area.

Another problem seems to have been fixed since the release I was using before. I drew a shape and filled it with grey then blured the edge and it worked. When doing the same with lightgrey the main part was lightgrey but the blured edge was still grey.

Anyway this is just for information in case anyone else runs into the same problem.
