IMAGETEAM™ 4600/4800 User’s Guide 8 - 5
Alternately, specify the number of pixels to cut from the outside margin of the
image; thus only the center pixels are transmitted.
nM Margin: cut n columns from the left, n + 1 columns from the right,
n rows from the top, and n + 1 rows from the bottom of the image.
Ship the remaining center pixels. Range: 1 - 238.
(Default = 0, or full image)
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 (default for RS-232)
4P Hmodem compressed
S - Pixel Ship: Can be used to decimate 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 (default)
3S ship every 3rd pixel, both horizontally and vertically
U - Document Image Filter: Sharpens the edges and smooths the area
between the edges of the transmitted text image. The Document Image Filter
enhances images of documents such as ID cards and prescriptions. This filter
should be used with gamma correction (see
page 8-4 ), with the imager in a
stand, and the image captured using the command:
IMGSNP1P0L168W90%32D
This filter typically provides better JPEG compression than the standard E -
Edge Sharpen command (see
page 8-6 ). This filter also works well when
shipping pure black and white images (1 bit per pixel). The optimal setting is
26U.
0U Document image filter off
(default)
26U Apply document image filter for typical document image
nU Apply document image filter using grayscale threshold n. Use
lower numbers when the image contrast is lower. 1U will have a
similar effect to 22e. Range: 0-255.
V - Blur Image: Smooths transitions by averaging the pixels next to the hard
edges of defined lines and shaded areas in an image.
0V Don’t blur
(default)
1V Blur
