Export to Image

Bar codes can easily be exported to any image format supported by WPF, including PNG, BMP, GIF, JPEG, and TIFF image formats.

It's easy to generate a BitmapSource from a symbology, simply by calling its ToBitmap method. When you have an image representation of a bar code, you can save it to a file or paste the image in other applications for usage.

Sample Code

This sample code creates a BitmapSource from a Code 39 extended bar code.

Code39ExtendedSymbology symbology = new Code39ExtendedSymbology();
symbology.Value = "ABC-123";
BitmapSource source = symbology.ToBitmap(96, 96);

This sample code takes the BitmapSource from the previous sample code and writes it to a PNG file whose path is assumed to be in outputPath.

FileStream outStream = new FileStream(outputPath, FileMode.Create);
PngBitmapEncoder enc = new PngBitmapEncoder();
enc.Frames.Add(BitmapFrame.Create((BitmapSource)outputImage.Source));
enc.Save(outStream);
outStream.Dispose();
