我喜欢已经提出的 WPF 选项,但这里它使用LockBits
and Bitmap
:
// get the raw image data
int width, height;
int[] data = GetData(out width, out height);
// create a bitmap and manipulate it
Bitmap bmp = new Bitmap(width,height, PixelFormat.Format32bppArgb);
BitmapData bits = bmp.LockBits(new Rectangle(0, 0, width, height),
ImageLockMode.ReadWrite, bmp.PixelFormat);
unsafe
{
for (int y = 0; y < height; y++)
{
int* row = (int*)((byte*)bits.Scan0 + (y * bits.Stride));
for (int x = 0; x < width; x++)
{
row[x] = data[y * width + x];
}
}
}
bmp.UnlockBits(bits);
使用(作为测试数据):
public static int[] GetData(out int width, out int height)
{
// diagonal gradient over a rectangle
width = 127;
height = 128;
int[] data = new int[width * height];
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
int val = x + y;
data[y * width + x] = 0xFF << 24 | (val << 16) | (val << 8) | val;
}
}
return data;
}
