Define Documentation

#define LOGIC_OP_LOOP	(	MODE,
		MASKSTRIDE		)

We do all logic ops on 4-byte GLuints.

Depending on bytes per pixel, the mask array elements correspond to 1, 2 or 4 GLuints.

void _swrast_logicop_ci_span	(	GLcontext *	ctx,
		struct gl_renderbuffer *	rb,
		SWspan *	span
	)

void _swrast_logicop_rgba_span	(	GLcontext *	ctx,
		struct gl_renderbuffer *	rb,
		SWspan *	span
	)

Apply the current logic operator to a span of RGBA pixels.

We can handle horizontal runs of pixels (spans) or arrays of x/y pixel coordinates.
