Description:
|
Prior to the image being written out to the file, the eye, target, and projection mode of the specified (or, active, if none is specified) view are (internally) changed by the system to agree with those of the view in the context of which
phl-data was generated. This extension returns the filename.
|
|
|
phl-data specifies
PHL data from
phl:compute or
phl:retrieve.
|
|
|
The optional
filename specifies the filename where images are sent; the default filename is
plotfile.ps.
|
|
|
The optional
color is a logical flag (#t or
#f) that indicates whether the color is to be sent to the file.
|
|
|
The optional
x-size and
y-size specify the dimensions, in millimeters, of a rectangle into which the printed image of the viewport is to fit as tightly as possible without distortion.
|
|
|
The optional
view specifies the view to print.
