Compression quality - The number that determines the degree of loss in the compression process. The minimum, 1, yields the smallest files; the maximum, 100, yields the largest files.
Gray Scale - Specifies whether saved images are in color or in grayscale.
Compression level - Specifies the compression level (0 to 9) with the default value of 4. The minimum, 0, means that the file is uncompressed and has the largest size. Upper compression levels require much time for compressing an image, but the resulting file will be smaller. The maximum, 9, means the slowest compression and the best compressed file size.
Interlaced - Specifies whether saved images are interlaced.
Compression type - The type of compression used to save images. Possible values are —
|Note:||If you use the CCITT Group 3 or CCITT Group 4 compression, TIFF images will be monochrome.|
