--- Comment #8 from Anastasius Focht <focht(a)gmx.net> ---
Hello Dmitry,

thanks for the patch. Unfortunately it still doesn't work.

Although bitmap data is now provided by the help of 'OLEPictureImpl_Save' it
seems the app stream write method doesn't expect the 'StdPicture' header
(preamble + size) in preceding 'IStream_Write' call, causing a different
internal error/code path (still same external "Invalid imagesize" error
though).

It rather expects the raw bitmap data via 'IStream_Write(pStm, This->data,
This->datalen, &dummy)' immediately.

...
1834         header[0] = (This->loadtime_magic != 0xdeadbeef) ?
This->loadtime_magic : 0x0000746c;
1835         header[1] = This->datalen;
1836         IStream_Write(pStm, header, 2 * sizeof(DWORD), &dummy);
1837         IStream_Write(pStm, This->data, This->datalen, &dummy);
1838         hResult = S_OK;

--- snip ---

I removed the 'StdPicture' header serialization call for testing purpose
(potentially breaking other things) and it allows the app to start.
Loading/viewing/annotating PDF works nicely.

This means we're on the right track but can't simply reuse
'OLEPictureImpl_Save' here.

Regards
