IsVectorFile Property

Summary

Gets a value indicating whether the image file or stream is a vector image format.

Syntax

Objective-C

C++/CLI

Java

Python

public bool IsVectorFile { get; }

@property (nonatomic, assign, readonly) BOOL isVectorFile;

public boolean isVectorFile()

public: 
property bool IsVectorFile { 
   bool get(); 
}

IsVectorFile # get  (CodecsVectorImageInfo)

Property Value

true if the image file or stream is a vector image format, false; otherwise. The default value is false.

Remarks

When the value of IsVectorFile is true, then the image file or stream passed to the RasterCodecs.GetInformation or RasterCodecs.GetInformationAsync is a vector image file such as DXF or DWG. The rest of the members of this class are valid and contain the original document logical size. The physical load (rasterization size) is calculated based on the current rasterization values and is stored in CodecsImageInfo.Width, CodecsImageInfo.Height, CodecsImageInfo.XResolution and CodecsImageInfo.YResolution. For more information, refer to CodecsVectorLoadOptions.

If the value of IsVectorFile is false, then the image file or stream is a raster image such as JPEG or TIFF. These files have physical size and the rest of the values of this class should not be used.

Example

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
 
public void CodecsVectorLoadOptionsExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "random.dxf"); 
 
   //Check if it is a vector file 
   CodecsImageInfo info = codecs.GetInformation(srcFileName, false); 
   Debug.WriteLine($"Is {srcFileName} a vector file? : {info.Vector.IsVectorFile}"); 
   Debug.WriteLine($"Units: {info.Vector.Unit}"); 
 
   //Parallelogram data 
   CodecsVectorImageInfo codecsVectorImageInfo = info.Vector; 
   Debug.WriteLine($"Parallelogram Max X: {codecsVectorImageInfo.ParallelogramMaxX}"); 
   Debug.WriteLine($"Parallelogram Max Y: {codecsVectorImageInfo.ParallelogramMaxY}"); 
   Debug.WriteLine($"Parallelogram Max Z: {codecsVectorImageInfo.ParallelogramMaxZ}"); 
   Debug.WriteLine($"Parallelogram Min X: {codecsVectorImageInfo.ParallelogramMinX}"); 
   Debug.WriteLine($"Parallelogram Min Y: {codecsVectorImageInfo.ParallelogramMinY}"); 
   Debug.WriteLine($"Parallelogram Min Z: {codecsVectorImageInfo.ParallelogramMinZ}"); 
 
   // Set the vector load options 
   // CodecsVectorOptions & CodecsVectorLoadOptions reference 
   codecs.Options.Vector.Load.BackgroundColor = new RasterColor(255, 255, 255); 
   codecs.Options.Vector.Load.BitsPerPixel = 24; 
   codecs.Options.Vector.Load.ForceBackgroundColor = true; 
   codecs.Options.Vector.Load.ViewWidth = 800; 
   codecs.Options.Vector.Load.ViewHeight = 800; 
   codecs.Options.Vector.Load.ViewMode = CodecsVectorViewMode.UseBest; 
 
   // Load the image 
   RasterImage image = codecs.Load(srcFileName); 
   // do something with the image here 
 
   // Clean up 
   image.Dispose(); 
   codecs.Dispose(); 
}
