Inherits From:
TDstActiveTransferMode
Inherited By:
None.
Purpose:
TGrayInvertDstTransferMode is a concrete class, derived from TDstActiveTransferMode, for inverting a grayscale color. This transfer mode determines the destination color's grayscale value, subtracts it from 1.0, and replaces the destination with it. This transfer mode is suitable for real-time interactions. Once you apply the transfer mode to an area, the original contents of that area can be restored by applying the operation again.
Instantiation:
Allocate on the heap or the stack.
Deriving Classes:
None.
Concurrency:
Not multithread safe.
Resource Use:
No special requirements.
- TGrayInvertDstTransferMode ()
- TGrayInvertDstTransferMode (const TGrayInvertDstTransferMode &)
Interface Category:
API.
Purpose:
- Default constructor.
- Copy constructor.
Calling Context:
- Called by the stream-in operators. You can also call this function directly.
- Called to copy an object.
Parameters:
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
virtual ~ TGrayInvertDstTransferMode ()
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
- virtual void GetResultingColor (const TColor & destColor, TColor & resultingColor) const
Interface Category:
API.
Purpose:
- Converts the destination color, destColor into the inverted, grayscale value of the original destination color. The resulting TColor is returned in resultingColor. The variable sourceColor is ignored.
- Converts the destination color, destColor into the inverted, grayscale value of the original destination color. The resulting TColor is returned in resultingColor.
Calling Context:
- Call this function directly.
- Call this function directly.
Parameters:
- const TColor & sourceColor -Ignored by this function
- const TColor & destColor -The color to be converted.
- TColor & resultingColor -The converted color.
- const TColor & destColor -The color to be converted.
- TColor & resultingColor -The converted color.
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
static void GetInvertDstResult (const TGrayColor & destColor, TGrayColor & resultingColor)
Interface Category:
API.
Purpose:
Converts the destination color, destColor into the inverted, grayscale value of the original destination color. The resulting TGrayColor is returned in resultingColor
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.
TGrayInvertDstTransferMode & operator =(const TGrayInvertDstTransferMode & 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:
