@ -5,6 +5,16 @@ Revision history for Gimp-Perl extension.
- data types for RADIO, SPINNER etc.. are guessed better now.
- added examples/guides_to_selection.
- added examples/burst, without even looking at it ;)
- warn about deprecated :auto behaviour, remove in next version.
- call displays_flush in more cases now.
- always leave a dummy dimension of 1 into the pdl, for gray and
indexed drawables. down the other road lies madness.
- implemented & added examples/map_to_gradient, needed for my next
plug-in ;)
- implemented & added examples/fire. I gained a bit of understanding
now.
- fixed a few bugs in Gimp::Fu. PF_PATTERN & friends confused the
current with the default value and didn't restore it properly.
1.1 Fri Jul 30 07:37:30 CEST 1999
- one of the most successful releases, in terms of features & bugfixes.

=head1 DESCRIPTION
This plug-in creates a kind of "burning" effect around a drawable. Both
black-on-white and white-on-black source images make sense and create
different effects (do not use displace with black-on-white drawables,
though ;).
Although the original colour of the image does not matter, supplying a
greyscale drawable (though working) does not look very cool.
