[magick-users] No decode delegate for image format JPEG?

[shrike at studio.imagemagick.org]

> So, in fact, the precompiled binaries do not have these delegates

The precompiled binaries are loaded with delegates such as JPEG and
PNG.  To determine what is supported type

  convert -list format

For the precompiled binaries you need to specify MAGICK_HOME (see
Quickstart.txt) so ImageMagick can locate its configuration files.
Type

  convert -debug all logo: test.miff

and it will clue you where it is looking for the configuration files.
