Imaging Commands
IR - Image Rotate:
1IR Rotate image 90 degrees to the right
2IR Rotate image 180 degrees (upside down)
3IR Rotate image 90 degrees to the left
J - JPEG Image Quality: Sets the desired quality when the JPEG image
format is selected. Higher numbers result in higher quality, but larger
files. Smaller numbers result in greater amounts of lossy compression,
faster transmission times, lower quality, but smaller files. (Default = 50)
nJ Image is compressed as much as possible while preserving quality
factor of n (n = 0 - 100)
0J worst quality (smallest file)
100J best quality (largest file)
K - Gamma Correction: Gamma measures the brightness of midtone
values produced by the image. You can brighten or darken an image
using gamma correction. A higher gamma correction yields an overall
brighter image. The lower the setting, the darker the image. A setting of
100 results in no adjustment to the image. The optimal setting for text
images is 50K.
0K Gamma correction off (default)
50K Apply gamma correction for brightening typical document image
nK Apply gamma correction factor n (n = 1-255)
L, R, T, B, M - Image Cropping: Ships a window of the image by speci-
fying the left, right, top, and bottom pixel coordinates. Device columns
are numbered 0 through 640, and device rows are numbered 0 through
480.
nL The left edge of the shipped image corresponds to column n of the
image in memory. Range: 000 - 640. (Default = 0)
