> You open the setup window via the menu preferences/setup in the main window of xsane.

> #### Reduce 16 bit image to 8 bit:

> > When the image is scanned with 16 bit/color then xsane does reduce the color depth to 8 bit/color before saving the image.

> #### Save 16 bit pnm in ascii format:

> > In general 16 bit pnm images are stored in binary format. When you want to create 16 bit ascii pnm images then enable this option. But keep in mind that you get huge files!

> #### Save posctscript zlib compressed (ps level 3):

> > Poscsript level 2 does not know about zlib compressed images. For postscript level 2 the images are stored in A85 compression. When you want to create zlib compressed (deflate) postscript files then enable this option. But keep in mind that you will not be able to print such files on postscript level 2 printers!

> #### Save PDF zlib compressed:

> > PDF images can be stored in A85 compression or in zlib compression. When you want to create zlib compressed (deflate) PDF files then enable this option.

> #### JPEG image quality:

> > If the image is saved in jpeg format this value defines the quality of the image. Low values mean low quality and low file size, high values mean high quality and high file size.

> #### PNG image compression:

> > If the image is saved in png format this value defines the compression level. The quality of the image keeps the same, low values mean low compression, large files and low compression time. High values mean high compression, smaller files and high compression time.

> #### TIFF zip compression rate:

> > If the image is saved in zlib compressed (deflate) tiff format this value defines the compression level. The quality of the image keeps the same, low values mean low compression, large files and low compression time. High values mean high compression, smaller files and high compression time.

> #### TIFF 16 bit image compression:

> > If the image is saved in 16 bit/color tiff format this selection defines if xsane does pack bits or no compression is used.

> #### TIFF 8 bit image compression:

> > If the image is saved in 8 bit/color tiff format this selection defines if xsane does pack bits, use JPEG DCT compression or no compression is used.

> #### TIFF lineart image compression:

> > If the image is saved in lineart tiff format this selection defines if xsane does pack bits, use CCIT Group 4 Fax compression, CCIT Group 3 Fax compression, CCIT 1D Huffman compression, JPEG DCT compression or no compression is used.
