adjustContrast(ImGearRasterPage,double,double,double,ImGearContrastModes,ImGearChannelRange,ImGearContrastOptions) Method

Processes the specified range of channels.

Can be applied only to raster pages with standard (non Run-Ends) DIB.

If ContrastMode is equal to ImGearContrastModes.PALETTE, DIB must have a palette.

Use method ImGearRasterProcessingVerifier.canApplyAdjustContrast method to check whether the operation can be performed.

This method adjusts contrast, brightness, and gamma.

Syntax

public static void adjustContrast( 
   ImGearRasterPage page,
   double contrast,
   double brightness,
   double gamma,
   ImGearContrastModes mode,
   ImGearChannelRange channels,
   ImGearContrastOptions options
)

Parameters

page

Image to adjust contrast.

contrast

Contrast value.

brightness

Brightness value.

gamma

Gamma value.

mode

One of the following values: ImGearContrastModes.PALETTE - image palette is adjusted. If the image does not have palette then an exception will be generated ImGearContrastModes.PIXEL - image pixels are adjusted ImGearContrastModes.AUTO - adjust mode depends on the image color space.

channels

Structure that defines channel range to process.

options

ImGearContrastOptions class object.

Processes the specified range of channels.

Can be applied only to raster pages with standard (non Run-Ends) DIB.

If ContrastMode is equal to ImGearContrastModes.PALETTE, DIB must have a palette.

Use method ImGearRasterProcessingVerifier.canApplyAdjustContrast method to check whether the operation can be performed.
