L, R, T, B, M - Image Cropping: Ships a window of the image by specifying the left, right, top, and bottom pixel coordinates. Device columns are numbered 0 through 639, and device rows are numbered 0 through 479. The resulting cropped image must have two or more rows and two or more columns of pixels or the IMGSHP command will fail (1x1 is not acceptable). For example, sending IMGSHP10L15R5T8B will cause a 6 column by 4 row image to be transmitted.
nL The left edge of the shipped image corresponds to column n of the image in memory. Range: 000 - 639. (Default = 0)
nR The right edge of the shipped image corresponds to column n - 1 of the image in memory. Range: 000 - 639. (Default = all columns, or 639 for VGA imager)
nT The top edge of the shipped image corresponds to row n of the image in memory. Range: 000 - 479. (Default = 0)
nB The bottom edge of the shipped image corresponds to row n - 1 of the image in memory. Range: 000 - 479. (Default = all rows, or 479 for VGA imager)
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 compressed (default for
4P Hmodem
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
