Translates the specified color in the image, and returns the nearest matching color in the destination image.

public:
int TranslateColor(
RasterImage^ destImage,
int rgb
)
destImage
Destination RasterImage object.
rgb
Value that specifies the color in the image to be translated.
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.
