Function Documentation

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.

plsA plot stream structure.
A PLDev *

Definition at line 2856 of file plctrl.c.

PLDLLIMPEXP void plCloseFile ( PLStream pls)

Closes output file unless it is associated with stdout.

plsA plot stream structure.

Definition at line 2625 of file plctrl.c.

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.

plsA plot stream structure.
newcolorA color structure to store the color in.
iIndex of the desired color.
ncolTotal number of colors (supported by the device?).

Definition at line 2520 of file plctrl.c.

PLDLLIMPEXP void plFamInit ( PLStream pls)

Initializes family file parameters.

plsA plot stream structure.

Definition at line 2741 of file plctrl.c.

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.

plsA plot stream structure.

Definition at line 2770 of file plctrl.c.

PLDLLIMPEXP void plGinInit ( PLGraphicsIn gin)

Just fills in the PLGraphicsIn with appropriate initial values.

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

Definition at line 2877 of file plctrl.c.

void PLDLLIMPEXP plgpls ( PLStream **  p_pls)

Definition at line 3672 of file plcore.c.

PLDLLIMPEXP void plOpenFile ( PLStream pls)

Definition at line 2561 of file plctrl.c.

void plP_getmember ( PLStream pls)

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

plsA plot stream structure.

Definition at line 2647 of file plctrl.c.

void plP_sfnam ( PLStream pls,

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

plsA plot stream.
fnamThe base file name of the plot files.

Definition at line 2690 of file plctrl.c.

PLDLLIMPEXP void plRotPhy ( PLINT  orient,
PLINT  xmin,
PLINT  ymin,
PLINT  xmax,
PLINT  ymax,

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.

orientNew plot orientation (0-3)
xminCurrent plot x minimum?
yminCurrent plot y minimum?
xmaxCurrent plot x maximum?
ymaxCurrent plot y maximum?
pxOld x coordinate mapped to new x coordinate.
pyOld y coordinate mapped to new y coordinate.
