# Slackware build script for jp2-pixbuf-loader

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Notes:

# - I'm using the latest git because it actually has some important fixes.

# - gdk-pixbuf2 upstream used to support jpeg2000 via jasper, but
#   removed it from their repo a while back. I could have done a
#   jasper-pixbuf-loader like I did for pcx, but jasper doesn't
#   fully support the jpeg2000 standard. This probably doesn't fully
#   support it either, but it does support more of it anyway.

# - I only ever test this with qiv. geeqie can display jpeg2000 without
#   installing this, and I don't really know what else on SBo might use it.

# - /usr/share/thumbnailers/jp2-pixbuf.thumbnailer is included in the
#   package, but it may not be useful. It's for GUI filemanagers. I
#   checked dolphin and thunar, and they already know how to display
#   thumbnails for .jp2 files without this package. Tried nautilus,
#   and it won't display thumbnails *with* this package. Not being
#   a user of any of the above, I have no idea what's going on and
#   no real motivation to spend any more time on it. Including the
#   thumbnailer doesn't *hurt* anything so I'll leave it in case
#   someone finds it useful for something.
