is 7.0.4-9 Not 7.0.5.4

I am reporting the bug for the version I used to test (7.0.5.4)

Thanks for identifying that it fails for your version also. But note that bug fixes only will be made in the next release. They will not be fix in the current or older releases.

With the older v7.0.3-5 on Windows 8.1, the result was good. So a bug was introduced later.

It first fails for me at IM 7.0.5.1. Before that it seemed fine. I do not see anything that appears relevant in the changelog for that version.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.
