Do you need a TIFFWriteTile() function? Probably TIFFWriteEncodedTile() may better suit for your needs. 2. You should use cropped buffer in your case (this is also happens when you write the last tile in a strip or column). Data in the buffer will be contiguous, i.e. after the end of the first scanline you should start the second one without any NULL bytes or so. Andrey -- Andrey V.
