IsPalette8Alpha Property

Summary

Determines whether the file contains 8-bit palettized image data + alpha.

Syntax
C#
VB
C++
Java
public bool IsPalette8Alpha { get; } 
Public ReadOnly Property IsPalette8Alpha As Boolean 
public boolean IsPalette8Alpha() 
public: 
property bool IsPalette8Alpha { 
   bool get(); 
} 

Property Value

true if the file contains 8-bit palettized image data + alpha; false, otherwise.

Example
C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Examples; 
 
public void CodecsImageInfoIsGray8AlphaExample() { 
   string fileName = @"<PNG_FILE_PATH>"; 
   using (RasterCodecs codecs = new RasterCodecs()) 
   { 
      CodecsImageInfo info = codecs.GetInformation(fileName, true); 
      if (info.IsGray8Alpha) 
      { 
         /* These files might get loaded as 32-bit by default.  
          * You can load them as 8-bit, alpha information is not needed.  
          */
