Function Documentation

void c_pladv

(

PLINT

page

)

Advance to subpage "page" or to the next page if "page" = 0.

Parameters

page	Subpage identifier or 0

Definition at line 34 of file plpage.c.

void c_plbop

(

void

)

Start new page. Should only be used with pleop().

Definition at line 118 of file plpage.c.

void c_plcalc_world	(	PLFLT	rx,
		PLFLT	ry,
		PLFLT *	wx,
		PLFLT *	wy,
		PLINT *	window
	)

Calculate world coordinates wx, and wy from relative device coordinates, rx and ry. Also, return the window index for which the world coordinates are valid. window is set to -1 and wx and wy to 0. if rx and ry do not correspond to valid world coordinates for any currently existing window.

Parameters

rx	Relative x device coordinates
ry	Relative y device coordinates
wx	Pointer to x world coordinate (after call)
wy	Pointer to y world coordinate (after call)
window	Pointer index of window for which the world coordinates are valid

void c_plclear

(

void

)

Clear current subpage. Subpages can be set with pladv before calling plclear. Not all drivers support this.

Definition at line 71 of file plpage.c.

void c_pleop

(

void

)

End current page.

Definition at line 101 of file plpage.c.

void c_plgspa	(	PLFLT *	xmin,
		PLFLT *	xmax,
		PLFLT *	ymin,
		PLFLT *	ymax
	)

Get subpage boundaries in absolute coordinates (mm from bottom left-hand corner of page).

Parameters

xmin	Pointer to PLFLT containing minimum x boundary after call
xmax	Pointer to PLFLT containing maximum x boundary after call
ymin	Pointer to PLFLT containing minimum y boundary after call
ymax	Pointer to PLFLT containing maximum y boundary after call

Definition at line 222 of file plpage.c.

PLINT plGetCursor

(

PLGraphicsIn *

plg

)

Wait for graphics input event and translate to world coordinates.

Author

Paul Casteels.

Parameters

plg	Pointer to PLGraphicsIn

Returns

0 if no translation to world coordinates is possible.

void plP_setsub

(

void

)

Set up the subpage boundaries according to the current subpage selected.

Definition at line 189 of file plpage.c.

void plP_subpInit

(

void

)

Set up plot parameters according to the number of subpages.

Definition at line 134 of file plpage.c.

PLINT plTranslateCursor

(

PLGraphicsIn *
