Class: THLSReplaceLightnessTransferMode

Declaration: HLSTransferModes.h

Interface Category:

API.

Inherits From:

TTransferMode

Inherited By:

None.

Purpose:

THLSReplaceLightnessTransferMode is a concrete class, derived from TTransferMode, for substituting the lightness component in the HLS (hue-lightness-saturation) color space. This transfer mode sets the resulting color's lightness to that of the source. The hue, saturation, and alpha are those of the destination. (The source and destination need not be THLSColors, and the resulting color is converted from HLS to the specified color space.)

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

None.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Member Function: THLSReplaceLightnessTransferMode::GetResultingColor

virtual void GetResultingColor (const TColor & sourceColor, const TColor & destColor, TColor & resultingColor) const

Interface Category:

API.

Call this function directly.

Parameters:

const TColor & sourceColor -The source color with the lightness value to use.
const TColor & destColor -The destination color to modify.
TColor & resultingColor -The modified destination color.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: THLSReplaceLightnessTransferMode::GetReplaceLightnessResult

static void GetReplaceLightnessResult (const THLSColor & sourceColor, const THLSColor & destColor, THLSColor & resultingColor)

Interface Category:

API.

Purpose:

Transforms the destination THLSColor to a color that has the same lightness value as the source color, but with the original hue, saturation, and alpha values. All arguments are passed as THLSColors.

Calling Context:

Call this function directly.

Parameters:

const THLSColor & sourceColor -The source color with the lightness value to use.
const THLSColor & destColor -The destination color to modify.
THLSColor & resultingColor -The modified destination color.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: THLSReplaceLightnessTransferMode::operator=

THLSReplaceLightnessTransferMode & operator =(const THLSReplaceLightnessTransferMode & source)

Interface Category:

API.

Purpose:

Assignment operator.

Calling Context:

Call this function by using the operator in an assignment statement.

Parameters:

const THLSReplaceLightnessTransferMode & source -The object to be copied.

Return Value:

A non-const reference to the left-hand side object.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.
