示例1: Bitmap
Image image = new Bitmap("InputColor.bmp");
ImageAttributes imageAttributes = new ImageAttributes();
int width = image.Width;
int height = image.Height;
float[][] colorMatrixElements = {
new float[] {2, 0, 0, 0, 0}, // red scaling factor of 2
new float[] {0, 1, 0, 0, 0}, // green scaling factor of 1
new float[] {0, 0, 1, 0, 0}, // blue scaling factor of 1
new float[] {0, 0, 0, 1, 0}, // alpha scaling factor of 1
new float[] {.2f, .2f, .2f, 0, 1}}; // three translations of 0.2
ColorMatrix colorMatrix = new ColorMatrix(colorMatrixElements);
imageAttributes.SetColorMatrix(
colorMatrix,
ColorMatrixFlag.Default,
ColorAdjustType.Bitmap);
e.Graphics.DrawImage(image, 10, 10);
e.Graphics.DrawImage(
image,
new Rectangle(120, 10, width, height), // destination rectangle
0, 0, // upper-left corner of source rectangle
width, // width of source rectangle
height, // height of source rectangle
GraphicsUnit.Pixel,
imageAttributes);示例2: new ColorMatrix(matrixItems)
