|
|
* The internal portion of the ScanOperation namespace.

|

|
|
* This is kept separate from ScanOperation.hpp so that files which use
|
|
* AlphaBlender.hpp or FormatConvert.hpp don't end up including all these
|
|
* implementation details.
|
|
*
|
|
* See Gdiplus\Specs\ScanOperation.doc for an overview of scan operations.
