I have a RenderTargetBitmap
, I need to convert it to BitmapImage
. Please check the code below.
RenderTargetBitmap bitMap = getRenderTargetBitmap();
Image image = new Image();// This is a Image
image.Source = bitMap;
In the above code I have used Image.Now I need to use a BitmapImage. How can I do this?
RenderTargetBitmap bitMap = getRenderTargetBitmap();
BitmapImage image = new BitmapImage();// This is a BitmapImage
// how to set bitMap as source of BitmapImage ?
Although it doesn't seem to be necessary to convert a RenderTargetBitmap
into a BitmapImage
, you could easily encode the RenderTargetBitmap
into a MemoryStream
and decode the BitmapImage
from that stream.
There are several BitmapEncoders in WPF, the sample code below uses a PngBitmapEncoder
.
var renderTargetBitmap = getRenderTargetBitmap();
var bitmapImage = new BitmapImage();
var bitmapEncoder = new PngBitmapEncoder();
bitmapEncoder.Frames.Add(BitmapFrame.Create(renderTargetBitmap));
using (var stream = new MemoryStream())
{
bitmapEncoder.Save(stream);
stream.Seek(0, SeekOrigin.Begin);
bitmapImage.BeginInit();
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.StreamSource = stream;
bitmapImage.EndInit();
}
