Hello,
I m using the libTiff with the TIFFWriteScanline function :
for (cbY = 0; cbY < ima.GetHeight(); ++cbY)
{
TIFFWriteScanline(out, (void *)ima[cbY], cbY, 0);
}
with ima my source image and ima[] each row of my image.
that s ok.
The problem is when I try to add compression. My filesize if even bigger
with the PACKBIT compression and just slightly smaller with the LZW
compression. (for differents images which normally can be compressed
correctly)
Is it correct, do I need to change anything to get smaller file ?
Thanks a lot,
Dlp
