Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".
I don't understand those error messages. However, there were some serious bugs introduced in 6.5.x when Magick made some changes to -convol for use with GPU processors. These were fixed after 6.0.x.
