ImageGear .NET
Solarize(ImGearRasterPage,Int32,ImGearContrastModes,ImGearChannelRange) Method
Example 




Image to process.
Lightness threshold above which colors of pixels are inverted.
One of the contrast processing modes: ImGearContrastModes.PALETTE, ImGearContrastModes.PIXEL, ImGearContrastModes.AUTO.
Channel range to solarize.
This method inverts the colors of pixels whose lightness exceeds the specified threshold.

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
// 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)
