A gray border is drawn around the viewport,// and a magenta border is around the SVG content.// In the right part of the page we locate just the content at a specific point// in the final image, and draw a purple border around it.//// This short sample shows how to measure and render an SVG image. // The SVG art used in this sample is from freesvg.org.publicclassRenderSvgContent {publicGcBitmapGenerateImage(Size pixelSize, float dpi, bool opaque, string[] sampleParams = null) {// Load the SVG:var svgPath = Path.Combine("Resources", "SvgMisc", "Smiling-Girl-offset.svg");usingvar svg = GcSvgDocument.FromFile(svgPath); var bmp = newGcBitmap(pixelSize.Width, pixelSize.Height, opaque, dpi, dpi);usingvar g = bmp.CreateGraphics(Color.White);var pt0 = newPointF(g.Resolution, g.Resolution); // Render the SVG content as specified by the SVG layout within viewport:var rcViewport = newRectangleF(pt0, svg.GetIntrinsicSize(SvgLengthUnits.Pixels));// Measure the content size/location relative to 'pt':var rcContent0 = g.MeasureSvg(svg, pt0);// Draw the SVG and viewport and content bounds: g.DrawSvg(svg, pt0); g.DrawRectangle(rcViewport, Color.DarkGray); g.DrawRectangle(rcContent0, Color.Magenta); // In the left part of the bitmap, render just the SVG content// aligning its top left corner to a specific point on the bitmap// (center of page horizontally, 1" from the top):var pt1 = newPointF(pixelSize.Width / 2, g.Resolution);// An alternative to GcGraphics.MeasureSvg() is GcSvgDocument.Measure(),// here we use it for illustration but these methods are calculations heavy,// so in a real app we would re-use the results from GcGraphics.MeasureSvg() above:var rcContent1 = svg.Measure(PointF.Empty, dpi); g.DrawSvg(svg, newPointF(pt1.X - rcContent1.X, pt1.Y - rcContent1.Y));// Add a border: g.DrawRectangle(newRectangleF(pt1, rcContent1.Size), Color.Purple); // Done:return bmp; } }}
