Inherits From:
TSrcActiveTransferMode
Inherited By:
None.
Purpose:
TGrayFilteredReplaceTransferMode is a concrete class, derived from TSrcActiveTransferMode, for converting a color to grayscale. It takes the source color and filters it through grayscale space to yield the corresponding gray color. The destination color is ignored.
Instantiation:
Allocate on the heap or the stack.
Deriving Classes:
None.
Concurrency:
Not multithread safe.
Resource Use:
No special requirements.
- TGrayFilteredReplaceTransferMode ()
- TGrayFilteredReplaceTransferMode (const TGrayFilteredReplaceTransferMode &)
Interface Category:
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.
Concurrency:
Not multithread safe.
Other Considerations:
None.
virtual ~ TGrayFilteredReplaceTransferMode ()
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:

- virtual void GetResultingColor (const TColor & sourceColor, TColor & resultingColor) const
Interface Category:
API.
Purpose:
- Converts a color to grayscale. It takes the source color and filters it through grayscale space to yield the corresponding gray color. The destination color, destColor, is ignored.
- Converts a color to grayscale. It takes the source color and filters it through grayscale space to yield the corresponding gray color.
Calling Context:
- Call this function directly.
- Call this function directly.
Parameters:
- const TColor & sourceColor -The color to be converted to gray scale.
- const TColor & destColor -Ignored by this function.
- TColor & resultingColor -The grayscale color corresponding to the sourceColor.
- const TColor & sourceColor -The color to be converted to gray scale.
- TColor & resultingColor -The grayscale color corresponding to the sourceColor.
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
TGrayFilteredReplaceTransferMode & operator =(const TGrayFilteredReplaceTransferMode & source)
Interface Category:
API.
Purpose:

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 the object streams itself out to.
Return Value:
Returns a reference to the stream the object streams itself out to.
Exceptions:

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 the object streams itself in from.
Return Value:
Returns a reference to the stream the object streams itself in from.
Exceptions:
