Inherits From:
TTransferMode
Inherited By:
None.
Purpose:
TRGBMultiplyTransferMode is a concrete class, derived from TTransferMode, that combines the RGB equivalents of two colors using multiplication. (The source and destination colors need not be TRGBColors, and the resulting color is converted from RGB to the specified color space.) The resultant color's red, green, and blue values are each the product of the source's and destination's values. The transparency values are similarly multiplied.
Instantiation:
Allocate on the heap or the stack.
Deriving Classes:
None.
Concurrency:
Not multithread safe.
Resource Use:
No special requirements.

API.
Purpose:
- Default constructor.
- Copy constructor.
Calling Context:
- Called by the stream-in operators. You can also call this constructor directly.
- Called to copy an object.
Parameters:
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.

Other Considerations:
None.
virtual ~ TRGBMultiplyTransferMode ()
Interface Category:
API.
Purpose:
Destructor.
Calling Context:
Called to destroy an object.
Parameters:
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
virtual void GetResultingColor (const TColor & sourceColor, const TColor & destColor, TColor & resultingColor) const
Interface Category:
API.
Purpose:
Returns a color whose RGB and transparency components are the product of the source's and destination's individual RGB and transparency components. All parameters are passed as TColor objects.
Calling Context:
Call this function directly.
Parameters:
- const TColor & sourceColor -The source color to multiply.
- const TColor & destColor -The destination color to multiply.
- TColor & resultingColor -The resulting, multiplied RGB color.
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
static void GetMultiplyResult (const TRGBColor & sourceColor, const TRGBColor & destColor, TRGBColor & resultingColor)
Interface Category:
API.
Purpose:
Returns a color whose RGB and transparency components are the product of the source's and destination's individual RGB and transparency components. All parameters are passed as TRGBColor objects.
Calling Context:
Call this function directly.
Parameters:
- const TRGBColor & sourceColor -The source color to multiply.
- const TRGBColor & destColor -The destination color to multiply.
- TRGBColor & resultingColor -The resulting, multiplied RGB color.
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
TRGBMultiplyTransferMode & operator =(const TRGBMultiplyTransferMode & 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.
virtual TStream & operator >>=(TStream & towhere) const
Interface Category:
API.
Purpose:
Stream-out operator.
Calling Context:
Called to stream out data.
Parameters:
- TStream & towhere -The stream that the object streams itself out to.
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.
virtual TStream & operator <<= (TStream & fromwhere)
Interface Category:
API.
Purpose:
Stream-in operator.
Calling Context:
Called to stream in data.
Parameters:
- TStream & fromwhere -The stream that the object streams itself in from.
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.
virtual ETransferModeClassID TemporaryTypeID () const
Interface Category:
API.
Purpose:
Returns the type of transfer mode this class represents.
Calling Context:
Call this function directly.
Parameters:
Return Value:
Returns an ETransferModeClassID with value kRGBMultiplyTransferMode.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
