GetPcdResolution Method

Summary

Examines a PhotoCD file to determine which resolutions it contains.

Syntax

C++

public int[] GetPcdResolution( 
   string fileName 
)

Public Function GetPcdResolution( _ 
   ByVal fileName As String _ 
) As Integer()

public: 
array<int>^ GetPcdResolution(  
   String^ fileName 
)

Parameters

fileName
A String containing the name of the PhotoCD file.

Return Value

An array of 6 boolean values that specifies if the resolution at the corresponding index exists.

Remarks

For the returned array of booleans, true means the corresponding resolution at this index exist in the file, while false means the corresponding resolution at the index does not exist in the file.

The following table defines the resolution value at each index:

Index	Meaning
0 (PCD Base Over 64)	Resolution 64 x 96
1 (PCD Base Over 16)	Resolution 128 x 192
2 (PCD Base Over 4)	Resolution 256 x 384
3 (PCD Base)	Resolution 512 x 768
4 (PCD 4 Base)	Resolution 1024 x 1536
5 (PCD 16 Base)	Resolution 2048 x 3072

Example

This example checks for a high resolution PCD image and loads it if possible.

using Leadtools.Svg; 
using LeadtoolsExamples.Common; 
 
void GetPcdResolutionExample(string pcdFileName) 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   // Get the PCD resolution information. 
   const int pcd4Base = 4; 
 
   int[] resolutions = codecs.GetPcdResolution(pcdFileName); 
 
   // Use high resolution if possible 
   if (resolutions[pcd4Base] != 0) 
   { 
      codecs.Options.Pcd.Load.Resolution = new LeadSize(1024, 1536); 
      Console.WriteLine("Loading 1024 x 1536"); 
   } 
   else 
   { 
      codecs.Options.Pcd.Load.Resolution = new LeadSize(512, 768); 
      Console.WriteLine("Loading 512 x 768"); 
   } 
 
   // Load the image at its own bits per pixel 
   RasterImage image = codecs.Load(pcdFileName, 0, CodecsLoadByteOrder.Bgr, 1, 1); 
   Console.WriteLine("Image size loaded: {0} by {1}", image.Width, image.Height); 
   image.Dispose(); 
 
   // Reset the default PCD resolution 
   codecs.Options.Pcd.Load.Resolution = new LeadSize(512, 768); 
 
   // Clean up 
   codecs.Dispose(); 
}
