ImageGear21.Processing.Advanced Assembly > ImageGear.Processing Namespace > ImGearEffects Class > Solarize Method : Solarize(ImGearRasterPage,Int32,ImGearContrastModes,ImGearChannelRange) Method

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.

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

Dim channels As ImGearChannelRange
 
ImGearEffects.Solarize(page, threshold, mode, channels)

public static void Solarize( 
   ImGearRasterPage page,

   ImGearChannelRange channels
)

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

)

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#	Copy Code
// 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);

Copy Code

// 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);
