CopyPaletteTo Method

Summary

Copies the palette of this RasterImage into a destination image.

Syntax

Objective-C

C++/CLI

Java

Python

public void CopyPaletteTo( 
   RasterImage destImage 
)

- (BOOL)copyPaletteTo:(LTRasterImage *)dstImage error:(NSError **)error

public void copyPaletteTo( 
   RasterImage destImage 
);

public: 
void CopyPaletteTo(  
   RasterImage^ destImage 
)

def CopyPaletteTo(self,destImage):

Parameters

destImage
The destination image into which the palette will be copied. You must have a valid image loaded for this method to work.

Remarks

Only the palette the image is copied. destImage must be allocated and must be 8-bit or less before this method is called. The source image (this RasterImage object and destImage must have the same BitsPerPixel. destImage existing palette will be destroyed before the copy is made.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void CopyDataCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "CopyDataCommand.bmp"); 
 
	// Load the source image from disk 
	RasterImage srcImage = codecs.Load(srcFileName); 
 
	// Create the destination image with same dimension as the source image 
	RasterImage destImage = new RasterImage( 
	   RasterMemoryFlags.Conventional, 
	   srcImage.Width, 
	   srcImage.Height, 
	   srcImage.BitsPerPixel, 
	   srcImage.Order, 
	   srcImage.ViewPerspective, 
	   srcImage.GetPalette(), 
	   IntPtr.Zero, 
	   0); 
 
	// Copy the image data from the source image to the destination image 
	CopyDataCommand command = new CopyDataCommand(); 
	command.DestinationImage = destImage; 
	command.Run(srcImage); 
 
	// Save it to disk 
	codecs.Save(destImage, destFileName, RasterImageFormat.Bmp, 24); 
 
	// Clean Up 
	srcImage.Dispose(); 
	destImage.Dispose(); 
	codecs.Dispose(); 
}
