Dim instance As BrightnessContrastOptions
Dim value As Byte
 
instance.TargetContrast = value
 
value = instance.TargetContrast

Remarks

The default value is 127.

This value sets the target contrast for document images, where contrast is calculated by comparing the 50th and 1st percentile brightness across the image. Images that have a contrast below the target range will have a contrast correction method recommended.
