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?".
You did not use the bible... the IM Examples (Cutting and Bordering)
Frame does not use background, it uses bordercolor! background is used for a seperate purpose as part of "montage"
And in your second example you want to use -bordercolor and -border, not -mattecolor and -frame. PS: always set the settings, before the operator that uses them!!!!
By the way - I do read your IM Examples very frequently. Stellar job!
Somehow I missed that paragraph about -bordercolor applying to the background of frames.
