S - Pixel Ship

Pixel Ship sizes an image in proportion to its original size. It decimates the image by shipping only
certain, regularly spaced pixels. For example, 4S would transmit every fourth pixel from every fourth
line. The smaller number of pixels shipped, the smaller the image, however, after a certain point the
image becomes unusable.
1S ship every pixel (default)
2S ship every 2nd pixel, both horizontally and vertically
3S ship every 3rd pixel, both horizontally and vertically

U - Document Image Filter

Allows you to input parameters to sharpen the edges and smooth the area between the edges of text
in an image. This filter should be used with gamma correction (see
reader in a stand, and the image captured using the command:
This filter typically provides better JPEG compression than the standard E - Edge Sharpen command
(see page 1-14). This filter also works well when shipping pure black and white images (1 bit per
pixel). The optimal setting is 26U.
Note: If you want to use an automatic image filter, rather than changing these settings manually, refer
to IU - Image Adaptive Text Filter
0U Document image filter off (default)
26U Apply document image filter for typical document image
n U Apply document image filter using grayscale threshold n. Use lower numbers when the
image contrast is lower. 1U will have a similar effect to setting
to 22e. Range: 0-255.
