I'm not able to write a tiled tiff file. The problem is TIFFWriteTile is not writing the amount of data being read by TIFFReadTile TIFFReadTile reads in 16384 bytes but TIFFWriteTile writes out only 2048 bytes.

Can anyone tell what's going wrong? (it's a single band img. and I set the tags also).

Code:

    for(y = 0; y < imageLength; y += tileLength) {
      for(x = 0; x < imageWidth; x += tileWidth) {
        size = TIFFReadTile(tif, buf, x, y, 0, 0);
        printf("read %d bytes\n", size);
        count++;
        printf("tile: %d\n", count);

        /* RGBTOLHS */
        /*Rgb2Lhs(&bufR, &bufG, &bufB, &L, &H, &S, tileLength, tileWidth);*/
        size = TIFFWriteTile(wtif, buf, x, y, 0, 0);
        printf("written %d bytes\n", size);
        printf("width %d bytes\n", x);
        printf("length %d bytes\n", y      }
    }

Pushkar,

I think we would need to see more of your program to know what is going wrong. It seems likely that the configuration of the output file is different from the input file. For instance, number of samples per pixel, bits per sample, or planar configuration. These would all result in writing a different amount of data than was read.

Best regards,
