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. 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) Example of Gamma Correction set to 0K: Example of Gamma Example of Gamma Correction set to 50K: Correction set to 255K: L, R, T, B, M - Image Cropping Note: Image Cropping should not be used with IMGSHP Modifiers (see page 8-5). 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. nL The left edge of the shipped image corresponds to column n of the image in memory. Range: 000 - 843. (Default = 0) nR The right edge of the shipped image corresponds to column n - 1 of the image in memory. Range: 000 - 843. (Default = all columns) nT The top edge of the shipped image corresponds to row n of the image in memory. Range: 000 - 639. (Default = 0) 8 - 10
