RadPdfProcessing provides support for SVG FormSource (vector graphics image format). The static FormSource.FromSvg method allows the possibility to insert a vector image in the PDF document. The following overloads are publicly available:

Method	Description
FormSource.FromSvg(string xml)	Creates a FormSource object from an SVG file provided as a xml.
FormSource.FromSvg(byte[] svgData)	Creates a FormSource object from an SVG file provided as a byte[].
FormSource.FromSvg(Stream stream)	Creates a FormSource object from an SVG file provided as a stream.

The following example shows how to insert an SVG image into a FormSource object using FixedContentEditor:

c#

string svgFilePath = "image.svg";
RadFixedDocument fixedDocument = new RadFixedDocument();
FixedContentEditor documentPageEditor = new FixedContentEditor(fixedDocument.Pages.AddPage());
int offset = 10;
documentPageEditor.Position.Translate(offset, offset);

FormSource svgHostForm = FormSource.FromSvg(File.ReadAllBytes(svgFilePath));
documentPageEditor.DrawForm(svgHostForm);
//draw the SVG FormSource with its original size

double aspectRatio = svgHostForm.Size.Width / svgHostForm.Size.Height;
//get the aspect ratio from the original SVG size
double desiredSVGWidth = 100;
double calculatedSVGHeight = desiredSVGWidth / aspectRatio;
documentPageEditor.Position.Translate(offset, svgHostForm.Size.Height + offset);
documentPageEditor.DrawForm(svgHostForm, new Size(desiredSVGWidth, calculatedSVGHeight));
//draw the SVG FormSource with desired width preserving the aspect ratio
