SetShading() [1/2]

void eVision.EPseudoColorLookup.SetShading	(	eVision.EC24	black,
		eVision.EC24	white,
		eVision.EColorSystem	colorSystem )

Sets up a pseudo-color mapping such that gray level 0 corresponds to color c24Black, gray level 255 corresponds to color c24White, and intermediate values are interpolated linearly between these two extremes.

Parameters

black	Color to be mapped on a black (value 0) pixel.
white	Color to be mapped on a white (value 255) pixel.
colorSystem	Color system in which interpolation takes place.

Furthermore, interpolation is performed in the designated color system. Even though interpolation is performed in an arbitrary color system, the extreme colors are specified in the RGB space. To obtain interesting shades of colors, it is recommended to interpolate on the hue component alone.

SetShading() [2/2]

void eVision.EPseudoColorLookup.SetShading	(	eVision.EC24	black,
		eVision.EC24	white,
		eVision.EColorSystem	colorSystem,
		bool	wrap )

Sets up a pseudo-color mapping such that gray level 0 corresponds to color c24Black, gray level 255 corresponds to color c24White, and intermediate values are interpolated linearly between these two extremes.

Parameters

black	Color to be mapped on a black (value 0) pixel.
white	Color to be mapped on a white (value 255) pixel.
colorSystem	Color system in which interpolation takes place.
wrap	If the color system supports a hue component, indicates whether hue wrap around must be applied.

Furthermore, interpolation is performed in the designated color system. Even though interpolation is performed in an arbitrary color system, the extreme colors are specified in the RGB space. To obtain interesting shades of colors, it is recommended to interpolate on the hue component alone.
