This looks like a dup question, it is, but no one has answered the actual question(s).
Here goes:
Basically, I'm rendering a ViewPort3D as a 2D snapshot in code, but need to convert that type
RenderTargetBitmap
into the type System.Drawing.Bitmap
(for further processing on the 2D side).
Dim bmpRen As New RenderTargetBitmap(1024, 550, 96, 96, PixelFormats.Pbgra32)
bmpRen.Render(Me.vp3dTiles) 'render the viewport as 2D snapshot
While I know how to save it to a file, I'd rather skip that step and convert the bmpRen
to a System.Drawing.Bitmap
type, but there is no method to do so.
RenderedTargetBitmap
is a BitmapSource
, so the BmpBitmapEncoder
can do the conversion for us:
This is in C#, but it should translate to VB without any problems.
RenderTargetBitmap bmpRen = new RenderTargetBitmap(1024, 550, 96, 96, PixelFormats.Pbgra32);
bmpRen.Render(vp3dTiles);
MemoryStream stream = new MemoryStream();
BitmapEncoder encoder = new BmpBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(bmpRen));
encoder.Save(stream);
Bitmap bitmap = new Bitmap(stream);
