Hwp_APNG

apng.hwp
========

This plugin enables Hollywood to load and save animations in the APNG format
(Animated Portable Network Graphics). The great advantage of the APNG format
is that it supports animations that use alpha channel transparency. Neither the
IFF ANIM nor the GIF ANIM formats support alpha channel transparency.
Furthermore,
APNG can also handle true colour frame data. A rival format to APNG is the MNG
format but APNG was chosen because more applications support it.

Once APNG.hwp is installed, Hollywood will 'automagically' be able to open
APNG animations. To save animations in the APNG format, use the new saver
constant #ANMFMT_APNG which will be registered by this plugin. Here's an
example how to save an animation in the APNG format:

BeginAnimStream(1, "test.apng", width, height, #ANMFMT_APNG)
For Local k = 1 to numframes Do WriteAnimFrame(1, ...)
FinishAnimStream(1)
