void set_window	(	TOPLEVEL *	toplevel,
		PAGE *	page,
		int	xmin,
		int	xmax,
		int	ymin,
		int	ymax
	)

Function Description

This function will set the current page constraints.

Parameters:

[in]	toplevel	The TOPLEVEL object.
[in,out]	page	The PAGE object to set constraints on.
[in]	xmin	The minimum x coordinate for the page.
[in]	xmax	The maximum x coordinate for the page.
[in]	ymin	The minimum y coordinate for the page.
[in]	ymax	The maximum y coordinate for the page.

void rotate_point	(	int	x,
		int	y,
		int	angle,
		int *	newx,
		int *	newy
	)

Function Description

This function will rotate a point coordinate by an arbitrary angle and return the new coordinate in the newx and newy parameters.

Parameters:

[in]	x	Input point x coordinate.
[in]	y	Input point y coordinate.
[in]	angle	Angle to rotate in degrees.
[out]	newx	Output point x coordinate.
[out]	newy	Output point y coordinate.

void rotate_point_90	(	int	x,
		int	y,
		int	angle,
		int *	newx,
		int *	newy
	)

Function Description

This function takes a point coordinate and rotates it by 90 degrees at a time. The new point coordinate is returned in newx and newy.

Parameters:

[in]	x	Input point x coordinate.
[in]	y	Input point y coordinate.
[in]	angle	Angle to rotate by (90 degree increments only).
[out]	newx	Output point x coordinate.
[out]	newy	Output point y coordinate.

void PAPERSIZEtoWORLD	(	int	width,
		int	height,
		int	border,
		int *	right,
		int *	bottom
	)

Function Description

This function takes the paper size and converts it to world coordinates. It supports landscape with a fixed aspect ratio.

Parameters:

[in]	width	Paper width. (units?)
[in]	height	Paper height. (units?)
[in]	border	Paper border size. (units?)
[out]	right	Right world coordinate. (units?)
[out]	bottom	Bottom world coordinate. (units?)

Todo:

Support more modes than just landscape only mode.
