Function Documentation

plAllocDev()

PLDLLIMPEXP PLDev* plAllocDev

(

PLStream *

pls

)

Allocates a standard PLDev structure for device-specific data, stores the address in pls->dev, and returns the address as well.

Parameters

pls	A plot stream structure.

Returns

A PLDev *

Definition at line 2866 of file plctrl.c.

plCloseFile()

PLDLLIMPEXP void plCloseFile

(

PLStream *

pls

)

Closes output file unless it is associated with stdout.

Parameters

pls	A plot stream structure.

Definition at line 2635 of file plctrl.c.

plcol_interp()

PLDLLIMPEXP void plcol_interp	(	PLStream *	pls,
		PLColor *	newcolor,
		int	i,
		int	ncol
	)

Initializes device cmap 1 entry by interpolation from pls->cmap1 entries. Returned PLColor is supposed to represent the i_th color out of a total of ncol colors in the current color scheme.

Parameters

pls	A plot stream structure.
newcolor	A color structure to store the color in.
i	Index of the desired color.
ncol	Total number of colors (supported by the device?).

plFamInit()

PLDLLIMPEXP void plFamInit

(

PLStream *

pls

)

Initializes family file parameters.

Parameters

pls	A plot stream structure.

Definition at line 2751 of file plctrl.c.

plGetFam()

PLDLLIMPEXP void plGetFam

(

PLStream *

pls

)

Starts new member file of family file set if necessary.

Note each member file is a complete graphics file (can be printed individually), although 'plrender' will treat a family as a single logical file if given the family name instead of the member name.

Parameters

pls	A plot stream structure.

Definition at line 2780 of file plctrl.c.

plGinInit()

PLDLLIMPEXP void plGinInit

(

PLGraphicsIn *

gin

)

Just fills in the PLGraphicsIn with appropriate initial values.

Parameters

gin	A plot graphics input (i.e. keypress or mouseclick) structure.

Definition at line 2887 of file plctrl.c.

plgpls()

void PLDLLIMPEXP plgpls

(

PLStream **

p_pls

)

Definition at line 3693 of file plcore.c.

plOpenFile()

PLDLLIMPEXP void plOpenFile

(

PLStream *

pls

)

Definition at line 2571 of file plctrl.c.

plP_getmember()

void plP_getmember

(

PLStream *

pls

)

Sets up next file member name (in pls->FileName), but does not open it.

Parameters

pls	A plot stream structure.

Definition at line 2657 of file plctrl.c.

plP_sfnam()

void plP_sfnam	(	PLStream *	pls,
		PLCHAR_VECTOR	fnam
	)

Sets up file name (with "%n" removed if present) & family stem name. Reserve some extra space (10 chars) to hold an optional member number.

Parameters

pls	A plot stream.
fnam	The base file name of the plot files.

Definition at line 2700 of file plctrl.c.

plRotPhy()

PLDLLIMPEXP void plRotPhy	(	PLINT	orient,
		PLINT	xmin,
		PLINT	ymin,
		PLINT	xmax,
		PLINT	ymax,
		PLINT *	px,
		PLINT *	py
	)

Rotates physical coordinates if necessary for given orientation. Each time orient is incremented, the plot is rotated 90 deg clockwise. Note: this is now used only to rotate by 90 degrees for devices that expect portrait mode.

Parameters

orient	New plot orientation (0-3)
xmin	Current plot x minimum?
ymin	Current plot y minimum?
xmax	Current plot x maximum?
ymax	Current plot y maximum?
px	Old x coordinate mapped to new x coordinate.
py	Old y coordinate mapped to new y coordinate.
