我有一个500x500的图像，并且我想以32x32的符号复制到该图像，该符号位于500x500图像的右上角。
我试图渲染它，但是它似乎不起作用：
var statusSymbol = new Image()
{
Source = new BitmapImage(new Uri(tempJPEG, UriKind.Relative))
};
WriteableBitmap wb = new WriteableBitmap(bitmap);
wb.Render(statusSymbol , new TranslateTransform() { X = 500-10, Y = 10 });
wb.Invalidate();
手动方式（有其优点和缺点）：
public Bitmap AddLogo(Bitmap original_image, Bitmap logo)
{
/// Add validation here (not null, logo smaller then original, etc..)
Bitmap with_logo = new Bitmap(original_image);
/// To get the right corner use:
int x_start_value = (original_image.Width - logo.Width) - 1;
int x_stop_value = original_image.Width -1;
///
/// You can add ofset (padding) by starting x and\or y from your value insted of 0
for (int y = 0; y < logo.Height; y++)
{
/// For left corner
///for (int x = 0; x < logo.Width; x++)
int logo_x = 0;
for (int x = x_start_value; x < x_stop_value; x++)
{
with_logo.SetPixel(x, y, logo.GetPixel(logo_x, y));
logo_x++;
}
}
return with_logo;
}
