所以我正在使用我在网络上发现的一些变体来将图像转换为灰度。我希望能够“淡出灰色”I.e.逐渐淡化颜色,这样我就可以从全彩色到部分彩色到纯灰色。
public static ColorMatrix ColorMatrixForGrayScale = new ColorMatrix(new[] {
new[] {.3f, .3f, .3f, 0, 0},
new[] {.59f, .59f, .59f, 0, 0},
new[] {.11f, .11f, .11f, 0, 0},
new float[] {0, 0, 0, 1, 0},
new float[] {0, 0, 0, 0, 1} });
public static Bitmap MakeGrayscale(Image original, int percent = 100)
{
ColorMatrix matrix = GetMatrix(percent); // returns a variation of the above.
//create a blank bitmap the same size as original
var newBitmap = new Bitmap(original.Width, original.Height);
//get a graphics object from the new image
var g = System.Drawing.Graphics.FromImage(newBitmap);
//create some image attributes
var attributes = new ImageAttributes();
//set the color matrix attribute
attributes.SetColorMatrix(matrix);
//draw the original image on the new image
//using the grayscale color matrix
g.DrawImage(original, new Rectangle(0, 0, original.Width, original.Height),
0, 0, original.Width, original.Height, GraphicsUnit.Pixel, attributes);
//dispose the Graphics object
g.Dispose();
return newBitmap;
}
所以问题是两部分。首先,我可以使用矩阵吗?如果是,我会改变什么,如果不是,什么是可行的方法?我正在考虑创建全灰度,然后将其与彩色图像合并(一些如何)。
