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
Example of Image
Rotate set to 0ir: Rotate set to 2ir:
J - JPEG Image Quality: Sets the desired quality when the JPEG image format is selected.
Higher numbers result in higher quality. Smaller numbers result in greater amounts of lossy
compression, faster transmission times, and lower quality. (Default = 50)

nJ Image is compressed as much as possible while preserving quality factor of n
(n = 0 - 100)

0J worst quality

100J best quality
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 is 50K. (This selection should only be
used for text images.)

0K Gamma correction off (default

60K Apply gamma correction for brightening typical document image

nK Apply gamma correction factor n (n = 1-255)
Correction set to 0K: Correction set to 50K: Correction set to 255K:
L, R, T, B, M - Image Cropping:
Ship a window of the image by specifying the left, right, top, and
bottom pixel coordinates. Device columns are numbered 0 through 640 or 752, depending on the
Image VGA setting (see Image VGA on page 28). 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 when Image VGA is On, 000 -752 when Image VGA is Off.
(Default = 0)

nR The right edge of the shipped image corresponds to column n - 1 of the image
in memory. Range: 000 - 640 when Image VGA is On, 000 - 752 when Image VGA is Off.
(Default = all columns)

nT The top edge of the shipped image corresponds to row n of the image in
memory. Range: 000 - 480. (Default = 0)

nB The bottom edge of the shipped image corresponds to row n - 1 of the image
in memory. Range: 000 - 480. (Default = all rows)
