How to save System.Windows.Controls.Image to a local drive

Question

How can I save the System.Windows.Controls.Image file to disk in the location: C: \ data \ 1.jpg Thanks

Answer 1

Perhaps try something in this direction:

private void SaveImageToJPEG(Image ImageToSave, string Location)
        {
            RenderTargetBitmap renderTargetBitmap = new RenderTargetBitmap((int)ImageToSave.Source.Width,
                                                                           (int)ImageToSave.Source.Height,
                                                                           100, 100, PixelFormats.Default);
            renderTargetBitmap.Render(ImageToSave);
            JpegBitmapEncoder jpegBitmapEncoder = new JpegBitmapEncoder();
            jpegBitmapEncoder.Frames.Add(BitmapFrame.Create(renderTargetBitmap));
            using (FileStream fileStream = new FileStream(Location, FileMode.Create))
            {
                jpegBitmapEncoder.Save(fileStream);
                fileStream.Flush();
                fileStream.Close();
            }
        }

You may need to combine with the dimensions in the RenderTargetBitmap to get what you want, but this should do the job. You can use different encoders, not just JpegBitmapEncoder.

German, but there is code to convert FrameworkElement to System.Drawing.Image, which can be easily saved. Link

- , :

public System.Drawing.Image ConvertControlsImageToDrawingImage(System.Windows.Controls.Image imageControl)
{
    RenderTargetBitmap rtb2 = new RenderTargetBitmap((int)imageControl.Width, (int)imageControl.Height, 90, 90, PixelFormats.Default);
    rtb2.Render(imageControl);

    PngBitmapEncoder png = new PngBitmapEncoder();
    png.Frames.Add(BitmapFrame.Create(rtb2));

    Stream ms = new MemoryStream();
    png.Save(ms);

    ms.Position = 0;

    System.Drawing.Image retImg = System.Drawing.Image.FromStream(ms);
    return retImg;
}

From there, you can use one of the Save () methods provided by the System.Drawing.Image class.
