ImageEn will fail during decompression of a TIFF file with the specification bellow. It is unable to decompress data. I have tested the TIFF with several TIFF viewers, and none had a problem with it.
The problem with the decompression then excalates to a complete application crash due to the way ImageEn handles the error.
I have put the file in question on one of our servers: https://neosys.si/helpdesk/public_files/MM/02357.TIF

You're right, current version doesn't support this (actually out of TIFF standard) file. The unsupported combination is:
- Compression = Deflate (not standard)
- FillOrder = 2 (not standard for RGB images, as your)
- PlanarConfig = a plane for each channel
Next minor release will support it. Anyway the change is very simple: just open tiffilt.pas, locate Strips2Bitmap procedure and this code:
if TIFFVars.FillOrder = 2 then
for i:=0 to szn[c]-1 do
ReverseBitsB( pbytearray(bufn[c])[i] );
just after "szn[c] := TIFFEnv.Stream.Read(bufn[c]^, szn[c]);" and inside the for..loop. |
