推荐答案

也许可以尝试以下方法:

Maybe try something along the lines of this method:

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();
            }
        }

您可能需要弄乱RenderTargetBitmap中的大小才能获得所需的内容，但这应该可以完成工作.您不仅可以使用JpegBitmapEncoder，还可以使用其他编码器.

You might need to mess around with the sizes in RenderTargetBitmap to get what you want, but this should get the job done. You can use different encoders than just JpegBitmapEncoder too.
