Solarize(ImGearRasterPage,Int32,ImGearContrastModes,ImGearChannelRange) Method

This method inverts the colors of pixels whose lightness exceeds the specified threshold.

Syntax

public static void Solarize( 
   ImGearRasterPage page,
   int threshold,
   ImGearContrastModes mode,
   ImGearChannelRange channels
)

public: static void Solarize( 
   ImGearRasterPage* page,
   int threshold,
   ImGearContrastModes mode,
   ImGearChannelRange channels
)

public:
static void Solarize( 
   ImGearRasterPage^ page,
   int threshold,
   ImGearContrastModes mode,
   ImGearChannelRange channels
)

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

'Usage
 
Dim page As ImGearRasterPage
Dim threshold As Integer
Dim mode As ImGearContrastModes
Dim channels As ImGearChannelRange
 
ImGearEffects.Solarize(page, threshold, mode, channels)

Parameters

page: Image to process.
threshold: Lightness threshold above which colors of pixels are inverted.
mode: One of the contrast processing modes: ImGearContrastModes.PALETTE, ImGearContrastModes.PIXEL, ImGearContrastModes.AUTO.
channels: Channel range to solarize.

Remarks

This method is not valid for use on 1-bit images.

The threshold is a value from 0 to the maximum value for a channel in the image. For example, if the image is 24bpp RGB, the threshold ranges from 0 to 255.

Example

C#
Visual Basic

// Channel range to adjust contrast.
ImGearChannelRange igChannelRange = new ImGearChannelRange(0, igRasterPage.DIB.ChannelCount);
// Solarize the image, inverting the contrast the contrast if above threshold.
ImGearEffects.Solarize(igRasterPage, 200,
    ImGearContrastModes.AUTO, igChannelRange);

' Channel range to adjust contrast.
Dim igChannelRange As New ImGearChannelRange(0, igRasterPage.DIB.ChannelCount)
' Solarize the image, inverting the contrast the contrast if above threshold.
ImGearEffects.Solarize(igRasterPage, 200, ImGearContrastModes.AUTO, igChannelRange)
