Questions and postings pertaining to the development of ImageMagick, feature enhancements, and ImageMagick internals. ImageMagick source code and algorithms are discussed here. Usage questions which are too arcane for the normal user list should also be posted here.
Reporting 8-bit is a legacy feature from before ImageMagick could support depths other than 8 & 16. We will add a patch to ImageMagick to fix the problem for the next release. Thanks.
