WrfelAnimator *PROFESSIONAL* ver 1.1á by Felix Domke

(translation into english by KB, i tried to translate the original german
 text as closely to the original as possible, so this weird style is NOT
 mine, just in case you care ;)

the WrfelAnimator is THE tool to create OpenCP wrfel mode animations.

the absolutely genious features are:
                - input format: PCX (no tga, tga sucks)
                - palette optimization: the palette of all frames will be
                  aligned to the first frame's palette.
                - output format: 100% compatible to old OpenCP animations
                  and new Wrfel Mode 2.0 with hi-res (320x200) and frame
                  rate control
                - RLE compression on demand
                - "strange frame optimization" which allows you creating
                   delays without enlarging the animation
the absolutely genious features, which are still missing, are:
                - delta compression (never gave good results on me)
                - start and loop frame (should be no problem to include, i
                  was just too lazy and had no animation to test it out...)
                - REAL palette optimization, actually, the first 16 colors
                  are thrown away and replaced with other ones, but it makes
                  more sense first finding 16 irrelevant colors (because
                  unused or looking almost like another color).

the WrfelAnimator works with a script which has the following format:

Version
[StrangeFrameOptimization] RLECompression
Title
NumFrames Delay Filename
NumFrames Delay Filename
NumFrames Delay Filename
...

"Version" has to be 0 or 1, 0 is cpanim 1.0, 1 is cpanim 2.0, when using
2.0-anims, the new wrfel mode ][ has to be used ([KB] that is, openCP
2.0q or higher ;). "StrangeFrameOptimization" is a nasty trick which enables
using the same frame several times after each other without actually STORING
it several times. Internally, the "framelen" value of the frame is simply
set to 0 then, for a strange reason this works wonderfully.
THIS VALUE HAS TO BE LEFT OUT WHEN CREATING 2.0 ANIMATIONS!
"RLECompression" applies an RLE compression to the animation before
saving ([KB] yes, really? ;). Sometimes this even has an effect, the file
wouldn't get larger because of this, so it can be simply left on.
"Title" is the max. 31 chars long title which is written in the anim file's
header. I don't know if the title REALLY belongs there, but why not - the
concerned 32 bytes were being set to 0 by makedmp.exe and skipped by openCP's
anim reader.
after this, a random number of "sections" follows.
Each section consists of the number of frames, the delay between them and
the file name.
when using 2.0-animations the delay is some weird value, such like 65536/fps
should work or stuff ([KB] EXACTLY!). when you state 3072 here, the anim
will be as fast as an 1.0-"delay=1"-animation. So in case of doubt just
state 3072 here and then look if it's too fast.
This value mustn't go beyond 65535.
The file name is supposed to contain some "%d"s or "%x"s, people not knowing
C's "printf" command should better leave their fingers off this tool :)

now a complete exampe for the lamers out there:

0
1 1
cubic player sucks!
11 2 intro%x.pcx
200 1 ani%03d.pcx

will create an animation of 200+10=210 frames, which are intro0.pcx to
introa.pcx and then ani000.pcx up to ani199.pcx.
Counting always starts with 0!

another example for the anim2.0 mode:
1
1
cubic player rocks!
11 6000 intro%x.pcx
200 3000 ani%03d.pcx

wap then has to be called with "wap <script> <dest.dat>". I won't comment
this further, if someone isn't able to do this, he's simply too dumb.

btw: to correctly play them, the animations have to be called "CPANI001.DAT",
"CPANI002.DAT" etc.
CPANI000.DAT should better not be used, the chance of exactly this file being
played is just too low.

what's planned for the next version:

                - delta compression
                - start frame and loop frame
                - real palette optimization
                - input: FLC, maybe other bitmap formats


err, yes, that was it.

have fun with this useless tool!
