	)		const

overridevirtual

Abstract implementation of getLinePtr().

Pixel type is unspecified (implementations that care about the exact type should get it via some other mechanism).

Parameters

line	The line number for the requested line.
lineWidth	Output parameter, the width of the returned line in pixel units.
buf	Buffer space that can optionally be used by the implementation.
bufWidth	The size of the above buffer, in pixel units.

Returns: Pointer to the first pixel of the requested line. This might be the same as the given 'buf' parameter or it might be some internal buffer.

Implements openmsx::FrameSource.
