Resolution Property

Summary
Gets or sets the resolution (Dots per inch) of the SVG document.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public LeadSizeD Resolution { get; set; } 
@property (nonatomic, assign) LeadSizeD resolution; 
public LeadSizeD getResolution() 
public void setResolution(LeadSizeD resolution) 
public: 
property LeadSizeD Resolution { 
   LeadSizeD get(); 
   void set (    LeadSizeD ); 
} 
Resolution # get and set (SvgBounds) 

Property Value

The resolution (Dots per inch) of the SVG document.

Remarks

The resolution is not part of the SVG standard. It is required by LEADTOOLS to convert pixel bounds to any logical units. Currently, LEADTOOLS saves this value in custom dpiX and dpiY attributes in the root svg element.

This property is set to the calculated resolution (dots per inch) of the document by SvgDocument.CalculateBounds.

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
using Leadtools.Forms.DocumentWriters; 
using Leadtools.Svg; 
 
using Leadtools.Document.Writer;

{ 
   // input directory 
   string inDir = LEAD_VARS.ImagesDir; 
   // output directory 
   string outDir = Path.Combine(LEAD_VARS.ImagesDir, "svgpages"); 
   if (!Directory.Exists(outDir)) 
      Directory.CreateDirectory(outDir); 
 
   using (var codecs = new RasterCodecs()) 
   { 
      // Set 300 as the default value for loading document files 
      codecs.Options.RasterizeDocument.Load.Resolution = 300; 
 
      codecs.ThrowExceptionsOnInvalidImages = false; 
 
      // Get all the files from input directory 
      foreach (var srcFileName in Directory.EnumerateFiles(inDir)) 
      { 
         Console.WriteLine("Checking {0}", srcFileName); 
         using (var info = codecs.GetInformation(srcFileName, false)) 
         { 
            // We can load as SVG if its document or vector (skipping SVG files themselves) 
            if (info.Format != RasterImageFormat.Unknown && // valid format 
               info.Format != RasterImageFormat.Svg && // not svg 
               (info.Document.IsDocumentFile || // a document 
               info.Vector.IsVectorFile)) // or vector

               // try to load the first page as SVG 
               try 
               { 
                  using (SvgDocument svgDocument = codecs.LoadSvg(srcFileName, 1, null) as SvgDocument) 
                  { 
                     // Save it to disk 
                     string name = Path.GetFileName(srcFileName).Replace(".", "-"); 
                     name = Path.ChangeExtension(name, "svg"); 
                     string dstFileName = Path.Combine(outDir, name); 
                     Console.WriteLine("Saving to {0}", dstFileName); 
                     svgDocument.SaveToFile(dstFileName, null); 
                  } 
               } 
               catch (Exception ex) 
               { 
                  Console.WriteLine(ex.Message); 
               } 
            }
