ImageMagick

AmigaOS4 notes
==============

Run "Unpack" from the command line to decompress all of the tools.

delegates.xml has been modified for use with the existing ffmpeg port.

Captions, annotations & labels may not work properly without running under a
POSIX shell such as abc-shell. If using the standard Amiga shell, instead of
caption:"One two three", try "caption:One two three".

When using text features for the first time, a font cache of Fonts:_TrueType
will be built in PROGDIR:fontconfig. This can take a while. You need the Arial
font installed if you don't specify a font name.

You can avoid the wait by specifying a .ttf file with -font.

If using wildcards in the AmigaOS shell, asterisks may need to be escaped with
another. Example: Work:Pics/image_**.jpg

To work with ILBM files, place ilbmtoppm and ppmtoilbm from the NetPBM
package, anywhere in $PATH or the main program directory.

The temporary path can be changed by setting the MAGICK_TEMPORARY_PATH
environment variable.


Changes for the OS4 port:

- Various fixes for Amiga paths.
- Symlinking is disabled.
  This was to avoid making 'physical' temporary copies when using external
  programs, but the symlinks were in a unix-path format. Disabling this is a
  quick workaround.

- Volume requesters are disabled while running. Parameters such as canvas:none
  are first parsed as a filename and would throw up a requester.

- Use RANDOM: (instead of /dev/urandom)
- Use IDOS->GetCliProgramName() so each utility can print the correct name for
  Usage help and errors.

- Allow * as a valid character in delegates.xml

Check the source archive on OS4Depot & Aminet if you are interested in seeing
the modifications made, along with explanations.
