L, R, T, B, M - Image Cropping
Note: Image Cropping should not be used with
Ships a window of the image by specifying the left, right, top, and bottom pixel coordinates. Device columns are numbered
0 through 1279, and device rows are numbered 0 through 959.
nL The left edge of the shipped image corresponds to column n of the image in memory. Range: 000 - 2591. (Default
= 0)
nR The right edge of the shipped image corresponds to column n - 1 of the image in memory. Range: 000 - 2591.
(Default = all columns)
nT The top edge of the shipped image corresponds to row n of the image in memory. Range: 000 - 1943. (Default = 0)
nB The bottom edge of the shipped image corresponds to row n - 1 of the image in memory. Range: 000 - 1943.
(Default = all rows)
Uncropped Image:
Example of Image Crop set to 200B:
Alternately, specify the number of pixels to cut from the outside margin of the image; thus only the center pixels are trans-
mitted.
nMMargin: 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: 0 - 970.
P - Protocol
Used for shipping an image. Protocol covers two features of the image data being sent to the host. It addresses the proto-
col used to send the data (Hmodem, which is an Xmodem 1K variant that has additional header information), and the for-
mat of the image data that is sent.
0P None (raw data)
2P None (default for USB)
3P Hmodem compressed (default for RS232)
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
