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?".
My command line is:
convert -verbose -quality 75 -density 72 -depth 8 -resize 159x159 -gravity Center -crop 106x106+0+0 {} small/{} | echo {}
for example.
Part of your problem may have been syntax order. Part was not getting rid of the headers and profiles (which you could do with -strip -resize rather than -thumbnail) and part was not adding +repage to remove the virtual canvas.
