Member Function Documentation

scaleX()

uint16 Lab::Utils::scaleX

(

uint16

x

)

Scales the x co-ordinates to that of the new display. In the room parser file, co-ordinates are set up on a 360x336 display.

scaleY()

uint16 Lab::Utils::scaleY

(

uint16

y

)

Scales the y co-ordinates to that of the new display. In the room parser file, co-ordinates are set up on a 368x336 display.

vgaScaleX()

int16 Lab::Utils::vgaScaleX

(

int16

x

)

Scales the VGA x coords to SVGA if necessary; otherwise, returns VGA coords.

vgaScaleY()

int16 Lab::Utils::vgaScaleY

(

int16

y

)

Scales the VGA y coords to SVGA if necessary; otherwise, returns VGA coords.

vgaUnscale()

Common::Point Lab::Utils::vgaUnscale

(

Common::Point

pos

)

Converts SVGA coords to VGA if necessary, otherwise returns VGA coords.

unDiff()

void Lab::Utils::unDiff	(	byte *	newBuf,
		byte *	oldBuf,
		Common::File *	sourceFile,
		uint16	bytesPerRow,
		bool	isVertical
	)

Does the undiffing between the bitmaps.
