About SVGCanvas SVGCanvas is a Delphi VCL Component fully written in ObjectPascal. SVGCanvas emulates a TCanvas (used by most drawing routines in Delphi) but outputs to a SVG-File instead to Screen. SVGCanvas makes it very easy to use existing graphics and outputting them to SVG by just changing a few lines. Benefits No Code Changes Required SVGCanvas emulates the standard TCanvas and also provides a TCanvas, Windows-API compatible Handle Embed Images T he SVGCanvas converts all images into SVG-Compatible JPG Images and can embed them into the document if needed. Easy to Use The SVGCanvas contains only a few settings that are documented and includes a sample application Print SVG The SVGCanvas works like the Delphi Printers Unit Convert Make existing applications able to export to the Scalable Vector Graphics by adding only a few lines Customizeable Buy the SVGCanvas and you'll receive the full code to modify it for your needs SVG Canvas Feature Matrix TCanvas Emulation (Provides a HDC Handle) Support of Text-Drawing Commands Support of Ellipse Support of Rect Support of RoundRect Support of Arc (AngleArc, Arc) Support of Polyline, Polygon Support of PolyBezier Support of BeginPath, EndPath Support of TextColor (Foreground) Support of Background Color Support of Images (external or embed) Creates SVG 1.1 Files Small Source File to include Native compiled into your application Comes with full source

SVG Canvas How To Use You can use the TSVGCanvas in the exact same way like you do with the Printers Unit of Delphi. First add SVGPrinter to your uses definition: uses Windows, Graphics, ..., SVGPrinter; Now you have access to the global SVGCanvas Object. To print something into the SVGCanvas you must first setup an output filename: SVGCanvas.Filename := 'c:\output.svg'; Then you call the BeginDoc() Routine to start the printing: SVGCanvas.BeginDoc('400px', '50%', 'My Title'); The Parameters are the Following: Parameter 1 - The Width of the Document, can be px, cm, pt or % or when left empty 100% is taken Parameter 2 - The Height of the Document, can be px, cm, pt or % or when left empty 100% is taken Parameter 3 - An additional Title that is shown in the Browser's Title Now you can draw to the SVGCanvas.Canvas Property which provides a usual TCanvas Object. SVGCanvas.Canvas.Pen.Color := clRed; SVGCanvas.Canvas.Pen.Style := psDot; SVGCanvas.Canvas.MoveTo(100, 100); SVGCanvas.Canvas.LineTo(200, 100); To finish the printing process call the EndDoc() Routine once: SVGCanvas.EndDoc(True); There's one parameter for this routine: Parameter 1 - Set to true if you want to preview the document after it was written To print for example the content of a TChart Object to SVG, use the following between the BeginDoc() and EndDoc(): Chart1.DrawToMetaCanvas(SVGCanvas.Canvas, Rect(0, 0, Chart1.Width, Chart1.Height)); Before printing you can setup the following properties of the SVGCanvas: Filename -- Must be set. Specifies the output SVG-File. Encoding -- The encoding used for the document. Default is "UTF-8". DrawMode: dwAntiAlias (default) - Antialiased shapes dwCrisp - Crisped shapes (more detailed) DPI -- Print Resolution This is automatically set to the screen resolution so that your documents look the same like in your Delphi Application Embedmages -- When true, all images are embed into the document otherwise they're saved as JPGs in the same folder JPEGQuality -- A Value from 0..100 setting up the quality and the image file size (has also effects when EmbedImages is set to true)
