Python
public RasterColor[] GetPalette() 
@property (nonatomic, copy, nullable) NSArray<LTRasterColor *> *palette 
public RasterColor[] getPalette() 
public:

def GetPalette(self): 

Return Value

The custom palette to use when converting the image.

Remarks

Use the SetPalette method to set the palette to use.

The custom palette to use. Specify this parameter as follows:

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void ColorResolutionCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName1 = Path.Combine(LEAD_VARS.ImagesDir, "Image1_colorres8.bmp"); 
	string destFileName2 = Path.Combine(LEAD_VARS.ImagesDir, "Image1_colorres4.bmp"); 
 
	// Load the source image from disk 
	RasterImage image = codecs.Load(srcFileName); 
 
	// First color-res it to 8 bits per pixel  using the Netscape palette into a seperate image 
	ColorResolutionCommand cmd = new ColorResolutionCommand(); 
	cmd.Mode = ColorResolutionCommandMode.CreateDestinationImage; 
	cmd.BitsPerPixel = 8; 
	cmd.Order = RasterByteOrder.Rgb; 
	cmd.DitheringMethod = RasterDitheringMethod.None; 
	cmd.PaletteFlags = ColorResolutionCommandPaletteFlags.UsePalette; 
	cmd.SetPalette(RasterPalette.Netscape()); 
	cmd.Run(image); 
 
	RasterImage destImage = cmd.DestinationImage; 
	Assert.IsTrue(destImage.BitsPerPixel == 8); 
 
	// Save it to disk 
	codecs.Save(destImage, destFileName1, RasterImageFormat.Bmp, 8); 
	destImage.Dispose(); 
 
	// Now color-res the image in-place to 4-bits per pixel using the Optimized palette 
	cmd.Mode = ColorResolutionCommandMode.InPlace; 
	cmd.BitsPerPixel = 4; 
	cmd.Order = RasterByteOrder.Rgb; 
	cmd.DitheringMethod = RasterDitheringMethod.None; 
	cmd.PaletteFlags = ColorResolutionCommandPaletteFlags.Optimized; 
	cmd.Run(image); 
	Assert.IsTrue(image.BitsPerPixel == 4); 
 
	// Save it to disk 
	codecs.Save(image, destFileName2, RasterImageFormat.Bmp, 4); 
 
	// Clean Up 
	destImage.Dispose(); 
	image.Dispose(); 
	codecs.Dispose(); 
}
