8 - 4 IMAGETEAM™ 2020/4620 System Manual
H - Histogram Stretch: Increases the contrast of the transmitted image. Not
available with some image formats.
0H No stretch
(default)
1H Histogram stretch
I - Invert Image: Used to rotate the image around the X or Y axis in fixed
mount applications where the imager is mounted upside down.
1IX Invert around the X axis (flips picture upside down)
1IY Invert around the Y axis (flips picture left to right)
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.

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.
