This is a simple chunk-based format employing RLE compression.<br />
<br />
File starts with "MPANIM" tag followed by 768-byte palette. First chunk should be "NORM" which contains 32-bit size, 14 bytes of data, and uncompressed frame (640x480).<br />
Other chunks start with "IMAGE=" tag, 32-bit size, 32-bit unknown value, and the rest is RLE data.<br />
<br />
RLE opcodes:<br />
* <code>D3</code> (ANM only) -- long run (1 byte run length and 1 byte run value)<br />
* <code>D4..DD</code> (ANM only) -- repeat next byte 1..10 times<br />
* <code>DE..FA</code> (ANM only) -- skip 1..27 pixels<br />
* <code>FB</code> -- not encountered<br />
* <code>FC</code> -- end of stream<br />
* <code>FD</code> -- next byte tells how many pixels to skip<br />
* <code>FE</code> -- next 16-bit value tells how many pixels to skip<br />
* <code>FF</code> -- next 32-bit value tells how many pixels to skip<br />
* all other opcodes are treated as pixel values<br />
<br />
As you can see, the difference between ANM and SEQ is that the latter has only skip codes and <code>D3..FA</code> values are treated as normal pixels.<br />
