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)
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 correc-
tion yields an overall brighter image. The lower the setting, the darker the image.
The optimal setting for text images is 50K.
Example:
L, R, T, B, M - Image Cropping
