Delegates: freetype jbig jpeg tiff zlib
after a successful compile and installation, IM seem to be missing certain key elements regarding delegates. From the initial installation, one of the commands issued was,
convert -size 1000x1000 xc:white white.png
This command failed with missing PNG delegate. I then installed compiled and installed the PNG library located here.

however, convert -version does not show the PNG library as installed. and now i get the following
Code: Select all
convert -size 1000x1000 xc:white white.png
this image format `XC' @ error/constitute.c/WriteImage/1167.
