6.1 Compression Settings for the TIFF Format.

Nero PhotoSnap has several compression processes available in the TIFF picture format.

You can set the desired process and the degree of compression in the Save As > settings

window.

The following settings options are available in the Compression area:

Option button

None

Uses no additional compression method.

Option button

LZW

Performs non-lossy fast compression using the Lempel, Ziv and Welch

method. The file size can be reduced by up to 50%. The loading time in

editing programs can, however, be longer. This method is particularly well

suited for gray scale and color pictures.

Option button

JPEG

Carries out a lossy JPEG compression. Using the JPEG compression

strength slide regulator you can define the degree of compression.

Option button

Group 3 fax

Performs a non-lossy compression by encoding isochromatic pixels and

saving the information separately. This method is used by all fax devices

and is well suited for black & white pictures.

Option button

Group 4 fax

Performs a non-lossy compression by encoding isochromatic pixels and

saving the information separately. The method is well suited for black &

white pictures.

Option button

CCITT RLE

Carries out a non-lossy compression using run-length encoding.

Isochromatic pixels are encoded using counters. This method is particu-

larly suitable for black & white pictures or pictures with large areas of the

same color.
