示例1: ShowOutputChannels
private void ShowOutputChannels(PaintEventArgs e)
{
//Create a bitmap from a file.
Bitmap bmp1 = new Bitmap("c:\\fakePhoto.jpg");
// Create a new bitmap from the original, resizing it for this example.
Bitmap bmp2 = new Bitmap(bmp1, new Size(80, 80));
bmp1.Dispose();
// Create an ImageAttributes object.
ImageAttributes imgAttributes = new ImageAttributes();
// Draw the image unaltered.
e.Graphics.DrawImage(bmp2, 10, 10);
// Draw the image, showing the intensity of the cyan channel.
imgAttributes.SetOutputChannel(ColorChannelFlag.ColorChannelC,
System.Drawing.Imaging.ColorAdjustType.Bitmap);
e.Graphics.DrawImage(bmp2, new Rectangle(100, 10, bmp2.Width, bmp2.Height),
0, 0, bmp2.Width, bmp2.Height, GraphicsUnit.Pixel, imgAttributes);
// Draw the image, showing the intensity of the magenta channel.
