MMBase uses ImageMagick's convert tool to build and convert its images.

ImageMagick is already part of the Red Hat distribution. Check its availability using:

  
  rpm -q ImageMagick
  
  

If ImageMagick is not available on your system, install it using up2date:

  
  up2date
  
  

or download it from the Red Hat Network:

and install it by hand:

  
  rpm -ihv ImageMagick-xxx.rpm
