Detailed Description
class openmsx::MLAAScaler< Pixel >
Scaler that uses a variation of the morphological anti-aliasing algorithm.
The paper that describes the original MLAA algorithm can be found here: http://visual-computing.intel-research.net /publications/papers/2009/mlaa/mlaa.pdf The original algorithm is a filter; it was adapted to scale the image. The classification of edges has been expanded to work better with the hand-drawn 2D images we apply the scaler to, as opposed to the 3D rendered images that the original algorithm was designed for.

Scales the image in the given area, which must consist of lines which are all equally wide.
Scaling factor depends on the concrete scaler.
- Parameters
-
src Source: the frame to be scaled. superImpose The to-be-superimposed image (can be nullptr). srcStartY Y-coordinate of the top source line (inclusive). srcEndY Y-coordinate of the bottom source line (exclusive). srcWidth The number of pixels per line for the given area. dst Destination: image to store the scaled output in. dstStartY Y-coordinate of the top destination line (inclusive). dstEndY Y-coordinate of the bottom destination line (exclusive).
Implements openmsx::Scaler< Pixel >.
