Interface Category:

API.

Inherits From:

TTransferMode

Inherited By:

None.

Purpose:

THLSTintTransferMode is a concrete class, derived from TTransferMode, for substituting the hue and saturation components in the HLS (hue-lightness-saturation) color space. This transfer mode sets the resulting color's tint--its hue and saturation--to that of the source. The lightness 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.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

Member Function: THLSTintTransferMode::GetResultingColor

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

Interface Category:

API.

Purpose:

Transforms the destination TColor to a color that has the same tint (hue and lightness values) as the source color, but with the original saturation and alpha values. All arguments are passed as TColors.

Calling Context:

Call this function directly.

Parameters:

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: THLSTintTransferMode::GetTintResult

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

Interface Category:

API.

Purpose:

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

Calling Context:

Call this function directly.

Parameters:

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: THLSTintTransferMode::operator=

THLSTintTransferMode & operator =(const THLSTintTransferMode & source)

Interface Category:

API.

Purpose:

Assignment operator.

Calling Context:

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

Parameters:

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.

Member Function: THLSTintTransferMode::operator>>=

virtual TStream & operator >>=(TStream & towhere) const

Interface Category:

API.

Purpose:

Stream-out operator.

Calling Context:

Called to stream out data.

Parameters:

Return Value:

Returns a reference to the stream the object streams itself out to.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: THLSTintTransferMode::operator<<=

virtual TStream & operator <<= (TStream & fromwhere)

Interface Category:

API.

Purpose:

Stream-in operator.

Calling Context:

Called to stream in data.

Parameters:

Return Value:

Returns a reference to the stream the object streams itself in from.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: THLSTintTransferMode::TemporaryTypeID

virtual ETransferModeClassID TemporaryTypeID () const

Interface Category:

API.

Purpose:
