L, R, T, B, M - Image Cropping
Note: Image Cropping should not be used with Image Auto Crop - IMGACP (see page 1-5).
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 - 1279.
(Default = 0)
nR The right edge of the shipped image corresponds to column n - 1 of the image in memory. Range: 000 - 1279.
(Default = all columns)
nT The top edge of the shipped image corresponds to row n of the image in memory. Range: 000 - 959. (Default =
0)
nB The bottom edge of the shipped image corresponds to row n - 1 of the image in memory. Range: 000 - 959.
(Default = all rows)
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: 0 - 478.
(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 compressed (default for RS-232)
4P Hmodem
