    Syntax
    'Declaration
     
    Public Overloads Shared Sub EqualizeContrast( _
       ByVal page As ImGearRasterPage, _

    'Usage

    ) 
    public:
    static void EqualizeContrast( 
       ImGearRasterPage^ page,
       ImGearContrastModes mode,
       ImGearChannelRange channels
    ) 

    Parameters

    page
    Page to equalize.
    mode
    One of the contrast processing modes: ImGearContrastModes.PALETTE, ImGearContrastModes.PIXEL, ImGearContrastModes.AUTO.
    channels
    Channel range to apply EqualizeContrast.
    Remarks
    If image is Indexed and not grayscale, modifies image's palette, otherwise modifies image's pixels. Processes only color channels.

    It 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 ImGearRasterProcessingVerifier.CanApplyEqualizeContrast method to check whether the operation can be performed.
