Hi,
I have managed to disable/change the things I need except for one - the
offset to the first IFD. I need it to be 8. I have replaced the lines in
tif_dirwrite.c:
tif->tif_diroff = (TIFFSeekFile(tif, (toff_t) 0, SEEK_END)+1) &~ 1;
diroff = tif->tif_diroff;
for
if (tif->tif_header.tiff_diroff == 0)
tif->tif_diroff = 8;
else
tif->tif_diroff = (TIFFSeekFile(tif, (toff_t) 0, SEEK_END)+1) &~ 1;
diroff = 8; //tif->tif_diroff;
And it seems to be working to a point. The problem is that it borks the
first couple of hundred scanlines. When I open with the gimp (2.0) it
tells me
...

Tiff: /home/antt/programming/tiff-3.7.1/tools/well.tif: Line length
mismatch at scanline 202 (got 2249, expected 2248)
Anyone got any ideas on this?
Cheers
