P - Protocol
Used for shipping an image. Protocol covers two features of the image data
being sent to the host. It addresses the protocol used to send the data
(Hmodem, which is an Xmodem 1K variant that has additional header
information), and the format of the image data that is sent.
0P None (raw data)
2P None
(default for USB)
3P Hmodem compressed
(default for RS-232)
4P Hmodem
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 page 8-11), with the imager in a stand, and the
image captured using the command:
IMGSNP1P0L168W90%32D
