overridevirtual

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 >.
