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)
