ISvgDocument Interface

Summary

Defines an SVG document.

Syntax

Objective-C

C++/CLI

Java

Python

public interface ISvgDocument : IDisposable, ISerializable

@protocol ISvgDocument <NSObject>

public interface ISvgDocument 
    extends java.io.Serializable

public interface class ISvgDocument : public System.IDisposable, System.Runtime.Serialization.ISerializable

class ISvgDocument(IDisposable, ISerializable):

Remarks

The SvgDocument class implements ISvgDocument. You should always cast ISvgDocument to SvgDocument to access the actual properties/methods of the SVG document class.

The interface is used by the LEADTOOLS framework to minimize dependencies between the various assemblies. For example, the Leadtools.Codecs.RasterCodecs.LoadSvg method (define in Leadtools.Codecs.dll) returns Leadtools.ISvgDocument (defined in Leadtools.dll) instead of Leadtools.Svg.SvgDocument (defined in Leadtools.Svg.dll). This way, Leadtools.Codecs.dll does not have a dependency on Leadtools.Svg.dll if SVG functionality is not required by your application.

Example

This example will load a PDF file as SVG and save it to disk

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Dicom; 
using Leadtools.Drawing; 
using Leadtools.Controls; 
using Leadtools.Svg; 
 
 
public static void SvgDocumentExample() 
{ 
   // The source PDF file 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Leadtools.pdf"); 
 
   using (var codecs = new RasterCodecs()) 
   { 
      // Set 300 as the default value for loading document files 
      codecs.Options.RasterizeDocument.Load.Resolution = 300; 
 
      // get the number of pages 
      int pageCount = codecs.GetTotalPages(srcFileName); 
 
      for (int pageNumber = 1; pageNumber <= pageCount; pageNumber++) 
      { 
         // Load this page as SVG using default options 
         using (SvgDocument svgDocument = codecs.LoadSvg(srcFileName, pageNumber, null) as SvgDocument) 
         { 
            // Save it to disk 
            string dstFileName = Path.Combine(LEAD_VARS.ImagesDir, string.Format("Page{0}.svg", pageNumber)); 
            svgDocument.SaveToFile(dstFileName, null); 
         } 
      } 
   } 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
