[WPF]Drawing.BitmapをBitmapSourceへ変換

csharpicon 昔のDLLがBitmapしか対応してないので、System.DrawingのBitmapをWPFのBitmapSourceへ変換する。

[System.Runtime.InteropServices.DllImport("gdi32.dll")]

public static extern bool DeleteObject(IntPtr hObject);

public BitmapSource BmpToWPFBmp(System.Drawing.Bitmap bitmap)

{

IntPtr hBitmap = bitmap.GetHbitmap();

BitmapSource source;

source = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());

DeleteObject(hBitmap);

return source;

}
