Detailed Description

Provides an OS-independent interface to printing under MSWindows and Mac OS X.

This class provides an OS-independent interface to printing under MSWindows and Mac OS X only. It allows to use all FLTK drawing, color, text, and clip functions, and to have them operate on printed page(s).

Member Function Documentation

int Fl_Native_Printer::endpage

(

void

)

To be called at the end of each page.

Returns:

0 iff OK.

int Fl_Native_Printer::getprintablerect	(	int *	x,
		int *	y,
		int *	w,
		int *	h
	)

Computes the origin and size of the printable area of the page.

Values are in the same unit as that used by FLTK drawing functions, are unchanged by calls to setorigin(), but are changed by rescale() calls.

Returns:

0 iff OK.

void Fl_Native_Printer::rescale	(	float	scale_x,
		float	scale_y
	)

Changes the scaling of page coordinates.

Use next getprintablerect() to get the new coordinates of the printable page area. Successive rescale() calls don't cumulate their effects.

Parameters:

	scale_x	Horizontal dimensions of plot are multiplied by this quantity
	scale_y	Vertical dimensions of plot are multiplied by this quantity

int Fl_Native_Printer::startjob	(	int	pagecount,
		int *	frompage = NULL,
		int *	topage = NULL
	)

Starts a print job.

Parameters:

[in]	pagecount	the total number of pages of the job
[out]	frompage	if non-null, *frompage is set to the first page the user wants printed
[out]	topage	if non-null, *topage is set to the last page the user wants printed

Returns:

0 iff OK

int Fl_Native_Printer::startpage

(

void

)

Starts a new printed page.

The page coordinates are initially in points, i.e., 1/72 inch, and with origin at the top left of the page or of the printable page area.

Returns:

0 iff OK
