page: Image to invert contrast.

mode: One of the contrast processing modes: ImGearContrastModes.PALETTE, ImGearContrastModes.PIXEL, ImGearContrastModes.AUTO.

channels: Channel range to invert contrast.

Inverts image contrast.

Syntax

Visual Basic

'Declaration
 
Public Overloads Shared Sub InvertContrast( _
   ByVal page As ImGearRasterPage, _
   ByVal mode As ImGearContrastModes, _
   ByVal channels As ImGearChannelRange _
)

'Usage
 
Dim page As ImGearRasterPage
Dim mode As ImGearContrastModes
Dim channels As ImGearChannelRange
 
ImGearRasterProcessing.InvertContrast(page, mode, channels)

public static void InvertContrast( 
   ImGearRasterPage page,
   ImGearContrastModes mode,
   ImGearChannelRange channels
)

public: static void InvertContrast( 
   ImGearRasterPage* page,
   ImGearContrastModes mode,
   ImGearChannelRange channels
)

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

Parameters

page: Image to invert contrast.
mode: One of the contrast processing modes: ImGearContrastModes.PALETTE, ImGearContrastModes.PIXEL, ImGearContrastModes.AUTO.
channels: Channel range to invert contrast.

Remarks

Processes specified range of channels.

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

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