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?".
The question is vague. How many "pictures with a light tone" does that image contain? 5, 6, or some other number?
Second: what does "cut pictures" mean? Maybe you want to crop to each bounding box. If so, then some pre-processing then "-connected-components" to get the bounding boxes, then crop in a script.
