How can I convert a WPF WriteableBitmap object to a System.Drawing.Image?
My WPF client app sends bitmap data to a web service, and the web service needs to construct a System.Drawing.Image on that end.
I know I can get the data of a WriteableBitmap, send the info over to the web service:
// WPF side:
WriteableBitmap bitmap = ...;
int width = bitmap.PixelWidth;
int height = bitmap.PixelHeight;
int[] pixels = bitmap.Pixels;
myWebService.CreateBitmap(width, height, pixels);
But on the web service end, I don't know how to create a System.Drawing.Image from this data.
// Web service side:
public void CreateBitmap(int[] wpfBitmapPixels, int width, int height)
{
System.Drawing.Bitmap bitmap = ? // How can I create this?
}
this blog post shows how to encode your WriteableBitmap as a jpeg image. Perhaps that helps?
If you really want to transfer the raw image data (pixels) you could:
I'd definitely prefer the first solution (the one described in the blog post).
