Examples

This example shows how to create an SVG image of the specified size and rasterize it to PNG.

[C#]

string dir = "c:\\temp\\";

int imageWidth = 100;
int imageHeight = 100;
int dpi = 96;

// Create an SVG image of 100x100 px.
Aspose.Imaging.FileFormats.Svg.Graphics.SvgGraphics2D graphics = new Aspose.Imaging.FileFormats.Svg.Graphics.SvgGraphics2D(imageWidth, imageHeight, dpi);

Aspose.Imaging.Pen pen = new Aspose.Imaging.Pen(Aspose.Imaging.Color.Yellow, 10);
Aspose.Imaging.Brushes.SolidBrush brush = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Red);

// Fill the entire image in red.
// Draw a yellow rectangle of 10px wide along the image boundaries.
graphics.FillRectangle(pen, brush, 0, 0, imageWidth, imageHeight);

// Get the final Svg image which includes all drawing commands
using (Aspose.Imaging.FileFormats.Svg.SvgImage svgImage = graphics.EndRecording())
{
    svgImage.Save(dir + "test.output.svg");
