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 have just been trying a bit of Anthony's code out on my localhost - windows 10 and 7.0.3 Q16 and I am getting some random noise. I have a 6. something version on my server and it is not creating the noise. A V7 problem?
I have reduced the command already to the above and I am not sure how much more to remove. It is the same with any input image so I did not bother uploading the input; just the frame image.
I can try to reduce the code further tomorrow night.
It is coming from the -draw "color x,y floodfill" step. But in conjunction with other commands. If I just do the floodfill step, it works fine on any image. Using IM 6 convert no color spots are showing. It could be due to getting some random fill color for the -draw rather than using the default white. I am not yet sure why you are getting the random colors from the -draw. But it does look like a bug to me in IM 7.
