Member Function Documentation

reflectionEffect()

void Pelrock::GraphicsManager::reflectionEffect	(	byte *	buf,
		int	x,
		int	y,
		int	width,
		int	height
	)

Water reflection: mirrors buf pixels at (x,y) for water-palette pixels.

calculateScaling()

ScaleCalculation Pelrock::GraphicsManager::calculateScaling	(	int	yPos,
		ScalingParams	scalingParams
	)

Returns the scaled width/height and scale parameters for Alfred at yPos.

scale()

byte* Pelrock::GraphicsManager::scale	(	int	scaleY,
		int	finalWidth,
		int	finalHeight,
		byte *	buf
	)

Scales a source frame (kAlfredFrameWidth × kAlfredFrameHeight) to (finalWidth × finalHeight) using the pre-computed scaling tables. Caller owns the returned buffer.
