Received but it seems the same as

Ok, I'm not good enough at dev to do this but it seems to be a good starting
point for some devs.

Most probably, a bad comment. I guess this comment was at first about opcodes
8200 and 8201, and then I found some files with opcode 8200 ( so I tried to
reverse its format ).

Oops, I was talking nonsense. I just checked that the libmwaw code for
ApplePicture can be called in LibreOffice by hand selecting the Mac Legacy
Drawing filter. This means that the ipict filter is called first and accepts to
convert the given image ( which I will send you by mail )

For this picture, I suppose that it is possible to modify ipict and add a
function to try to retrieve a bitmap by mimicking the code of
"ApplePictParser::readQuicktime".
Note:
Apple Picture can be a mixture of bitmaps and vector graphics. ipict can call
codes to work on bitmaps (for example, draw a rectangle in XOR mode, ...), so
it is often better. In libmwaw, I don't have such a code, so I create only a
vector graphic, (i.e. in this case, I add a rectangle and ignore the XOR mode).

It seems to talk about movie format.

Reading code from src/lib/ApplePictParser.cxx, I see:
1494 case 0x8200: {
1495 MWAWEmbeddedObject picture;
1496 MWAWBox2f bdBox;
1497 if (!readQuicktime(picture,bdBox))
1498 return false;
...
1506 break;
1507 }
1508 case 0x8201: {
...
1512 MWAW_DEBUG_MSG(("ApplePictParser::readZone: reading compressed
Quicktime is not implemented\n"));
...
1515 break;
1516 }
but according to
https://developer.apple.com/library/archive/documentation/mac/QuickDraw/QuickDraw-461.html
8200 is for compressed code and 8201 for uncompressed mode.
I see in LO that libmwaw is still used and uses its last version.
download.lst contains:
184 export MWAW_VERSION_MICRO := 21
185 export MWAW_TARBALL := libmwaw-0.3.$(MWAW_VERSION_MICRO).tar.xz
What does disable pct filter in libmwaw?
I mean "ApplePictParser" is present in Library_mwaw.mk since:
commit 6b0585a5b7e32d9acb6d8bc5f15d187959c7cc5b
Author: David Tardon
Date: Mon Aug 24 20:49:00 2015 +0200
upload libmwaw 0.3.6
Perhaps LO ipict part could use libmwaw which could itself use libtiff when
tiff is concerned.
Now if it's the case, I don't know how to do this.
