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; 
 
 
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.  
			 */ 
			using (RasterImage image = codecs.Load(fileName, 8, CodecsLoadByteOrder.Gray, 1, 1)) 
			{ 
				/* Do something with the bitmap */ 
				Console.WriteLine("BitsPerPixel = " + image.BitsPerPixel); 
			} 
		} 
	}
