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 RS-232)
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
