This is a bug and will be fixed in 6.8.7.1

You need so specify the event type for the debug parameter: http://www.imagemagick.org/script/comma ... .php#debug

The method 'MagickWriteImageFile' uses the filename property of NewMagickWand to determine the output type. You should change this to modify the format of the output file.

Have you tried to reproduce this problem with a newer version of ImageMagick?

Can you post a link to your input image?

I have committed a fix to round up odd-width images. This will be fixed in the next release of ImageMagick (6.8.7-1). Thanks for reporting this.

This looks like a bug in GhostScript. Have you tried to convert the pdf from the command line? What version of GhostScript are you using? An upgrade to 9.10 might fix the issues.

A patch has been submitted to the ImageMagick Subversion trunk. Thanks. This will be fixed in the next release 6.8.7-0.

Have you tried a newer version of ImageMagick? Your version is almost a year old.
