public int TranslateColor( 
   RasterImage destImage,
   int rgb
)

'Declaration
 
Public Overloads Function TranslateColor( _
   ByVal destImage As RasterImage, _
   ByVal rgb As Integer _
) As Integer

'Usage
 
Dim instance As RasterImage
Dim destImage As RasterImage
Dim rgb As Integer
Dim value As Integer
 
value = instance.TranslateColor(destImage, rgb)

public int TranslateColor( 
   RasterImage destImage,
   int rgb
)

-(unsigned int)translateColorRgb:(LTRasterImage*)destImage 
                             rgb:(unsigned int)rgb;

public int translateColor(
  RasterImage destImage, 
  int rgb
)

 function Leadtools.RasterImage.TranslateColor(RasterImage,Int32)( 
   destImage ,
   rgb 
)

public:
int TranslateColor( 
   RasterImage^ destImage,
   int rgb
)

Parameters

destImage: Destination RasterImage object.
rgb: Value that specifies the color in the image to be translated.

Return Value

The color value or the palette index of the nearest matching color in the destination image. If the destination image is 8 bits per pixel or less, this is always the palette index. Otherwise, it is the color value.

When creating a target image for animation, you can use this method to ensure that the correct color is specified as the background color.

The reverse of this method (to get a true RGB color value from a palette index color), use GetTrueColorValue.
