Examples

The following example uses this method to render the read svg file to wpfBitmap:

Copy
var readerSvg = new Ab2d.ReaderSvg();
readerSvg.Read(@"c:\mySample.svg");

// Render to bitmap
var wpfBitmap = readerSvg.RenderToBitmap(Brushes.White);

The next example uses the RenderToBitmap(Int32, Int32, Brush) method to render the read svg file to image with custom size and saves it to disk:

Copy
var readerSvg = new Ab2d.ReaderSvg();
readerSvg.Read(@"c:\mySample.svg");

// Render to bitmap with 1024 width - height will be set automatically so that the
// Image aspect ratio is preserved
var wpfBitmap = readerSvg.RenderToBitmap(1024, 0, Brushes.White);

var encoder = new System.Windows.Media.Imaging.PngBitmapEncoder();
// Uncomment to save to jpg
//var encoder = new JpegBitmapEncoder();
//encoder.QualityLevel = 85;

encoder.Frames.Add(System.Windows.Media.Imaging.BitmapFrame.Create(wpfBitmap));

using (var stream = System.IO.File.OpenWrite("c:\\svgImage.png"))
{
    encoder.Save(stream);
}
