readPict()

void Lab::DisplayMan::readPict	(	const Common::String	filename,
		bool	playOnce = true,
		bool	onlyDiffData = false,
		byte *	memoryBuffer = nullptr
	)

Reads in a picture into the display bitmap.

doTransition()

void Lab::DisplayMan::doTransition	(	TransitionType	transitionType,
		const Common::String	filename
	)

Does a certain number of pre-programmed wipes.

blackScreen()

void Lab::DisplayMan::blackScreen

(

)

Changes the front screen to black.

whiteScreen()

void Lab::DisplayMan::whiteScreen

(

)

Changes the front screen to white.

blackAllScreen()

void Lab::DisplayMan::blackAllScreen

(

)

Changes the entire screen to black.

drawPanel()

void Lab::DisplayMan::drawPanel

(

)

Draws the control panel display.

setUpScreens()

void Lab::DisplayMan::setUpScreens

(

)

Sets up the Labyrinth screens, and opens up the initial windows.

drawMessage()

void Lab::DisplayMan::drawMessage	(	Common::String	str,
		bool	isActionMessage
	)

Draws a message to the message box.

rectFill()

void Lab::DisplayMan::rectFill	(	uint16	x1,
		uint16	y1,
		uint16	x2,
		uint16	y2,
		byte	color
	)

Fills in a rectangle.

flowText()

int Lab::DisplayMan::flowText	(	TextFont *	font,
		int16	spacing,
		byte	penColor,
		byte	backPen,
		bool	fillBack,
		bool	centerh,
		bool	centerv,
		bool	output,
		Common::Rect	textRect,
		const char *	text,
		Image *	targetImage = nullptr
	)

Dumps a chunk of text to an arbitrary box; flows it within that box and optionally centers it. Returns the number of characters that were processed.

Note

Every individual word MUST be int16 enough to fit on a line, and each line less than 255 characters.

Parameters

font	Pointer on the font used
spacing	How much vertical spacing between the lines
penColor	Pen number to use for text
backPen	Background color
fillBack	Whether to fill the background
centerh	Whether to center the text horizontally
centerv	Whether to center the text vertically
output	Whether to output any text
textRect	Coords
text	The text itself

setAmigaPal()

void Lab::DisplayMan::setAmigaPal

(

uint16 *

pal

)

Converts a 16-color Amiga palette to a VGA palette, then sets the VGA palette.

writeColorRegs()

void Lab::DisplayMan::writeColorRegs	(	byte *	buf,
		uint16	first,
		uint16	numReg
	)

Writes any number of the 256 color registers.

Parameters

buf	A char pointer which contains the selected color registers. Each value representing a color register occupies 3 bytes in the array. The order is red, green then blue. The first byte in the array is the red component of the first element selected. The length of the buffer is 3 times the number of registers selected.
first	The number of the first color register to write.
numReg	The number of registers to write.

checkerBoardEffect()

void Lab::DisplayMan::checkerBoardEffect	(	uint16	penColor,
		uint16	x1,
		uint16	y1,
		uint16	x2,
		uint16	y2
	)

Overlays a region on the screen using the desired pen color.

getCurrentDrawingBuffer()

byte* Lab::DisplayMan::getCurrentDrawingBuffer

(

)

Returns the base address of the current VGA display.

scrollDisplayX()

void Lab::DisplayMan::scrollDisplayX	(	int16	dx,
		uint16	x1,
		uint16	y1,
		uint16	x2,
		uint16	y2,
		byte *	buffer
	)

Scrolls the display in the x direction by blitting. The _tempScrollData variable must be initialized to some memory, or this function will fail.

scrollDisplayY()

void Lab::DisplayMan::scrollDisplayY	(	int16	dy,
		uint16	x1,
		uint16	y1,
		uint16	x2,
		uint16	y2,
		byte *	buffer
	)

Scrolls the display in the y direction by blitting.

freeFont()

void Lab::DisplayMan::freeFont

(

TextFont **

font

)

Closes a font and frees all memory associated with it.

textHeight()

uint16 Lab::DisplayMan::textHeight

(

TextFont *

tf

)

Returns the height of a specified font.
