示例1: Decode
public RadBitmapData Decode(Stream stream)
{
Metafile metaFile = new Metafile(stream);
int width = metaFile.Width;
int height = metaFile.Height;
float scaleFactor = 1f;
if (metaFile.Width > maxPixelSize ||
metaFile.Height > maxPixelSize)
{
scaleFactor = Math.Max((float)metaFile.Width / (float)maxPixelSize, (float)metaFile.Height / (float)maxPixelSize);
width = (int)(width / scaleFactor);
height = (int)(height / scaleFactor);
}
// Create a PictureBox control and load the metafile
PictureBox box = new PictureBox();
box.Width = width;
box.Height = height;
box.BackColor = Color.White;
box.SizeMode = PictureBoxSizeMode.StretchImage;
box.Image = metaFile;
// Create snapshot of the PictureBox and save it as a bitmap
Bitmap bmp = new Bitmap(width, height);
box.DrawToBitmap(bmp, new Rectangle(0, 0, width, height));
//load the image in WPF
RadBitmap result = null;
RadBitmapData data = null;
using (MemoryStream output = new MemoryStream())
{
BitmapImage image = new BitmapImage();
image.BeginInit();
bmp.Save(output, this.encoder, null);
output.Seek(0, SeekOrigin.Begin);
image.StreamSource = output;
image.EndInit();
result = new RadBitmap(image);
data = new RadBitmapData(result.Width, result.Height, result.GetPixels());
}
return data;
