Hello,
I would like to write a TIFF image tile by tile (because I m processing
the image tile by tile in order to save memory) so reading the TIFF
specs, I found the TIFFWriteTile function. I tried to use it but with no
success, does anyone have an example on how to use it ?
Do I need to create the file before ? (I mean the complete file size)
In pseudo code I would like to do that:
WriteTile(myImageTile, x, y)
{
myTiffFile = openTiff("w"); // for the first Tile, the others are opened
with "a" ?
TIFFWriteTile(myTiffFile, myImageTile, x, y, 0, 0);
closeTiff(myTiffFile);
}
any help or ideas or URL ??
Many thanks,
Dlp
