8 - 7
IR - Image Rotate
0ir Image as snapped (rightside up) (default)
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)
100Jbest 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. 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 = 0-1,000)
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 1279, and device rows are numbered 0 through 959.
