  Delegate command file.

  Commands which specify

    decode="in_format" encode="out_format"

  specify the rules for converting from in_format to out_format These
  rules may be used to translate directly between formats.

  Commands which specify only

    decode="in_format"

  specify the rules for converting from in_format to some format that
  ImageMagick will automatically recognize. These rules are used to
  decode formats.

  Commands which specify only

   encode="out_format"

  specify the rules for an "encoder" which may accept any input format.

  For delegates other than ps:*, pcl:*, and mpeg:* the substitution rules are
  as follows:

    %i  input image filename
    %o  output image filename
    %u  unique temporary filename
    %z  secondary unique temporary filename
    %#  input image signature
    %b  image file size
    %c  input image comment
    %g  image geometry
    %h  image rows (height)
    %k  input image number colors
    %m  input image format
    %p  page number
    %q  input image depth
    %s  scene number
    %w  image columns (width)
    %x  input image x resolution
    %y  input image y resolution
