Parameters

brightness: The brightness intensity from -100 to 100.
contrast: The contrast intensity from -100 to 100.

Exceptions

Exception	Description
ProcessorException	A Processor exception.

Remarks

Some images describe more shades of gray than the human eye can discriminate. It is widely held that 256 shades are discernable. This method calculates a factor to multiply the values by to convert the selected range of grays to 256.

In order to further process or save 9-bit to 16-bit grayscale images, this method may need to be called first.

Note: Available in Professional edition.

Example

// create the processor class
Accusoft.ImagXpressSdk.Processor processor = new Accusoft.ImagXpressSdk.Processor( );
// associate it with a 8 to 16 bit per pixel image
processor.Image = highGrayImageX;
// apply the standard grayscale transform making the image brighter and enhancing the contrast
processor.ApplyGrayscaleTransform( 30, 10 );
