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?".
Can you post a URL to one of your DPX files so we can download and reproduce the problem. If we can reproduce it, we'll patch the DPX coder to fix the problem.
