The graPHIGS Programming Interface : Subroutine Reference
GPRQSK - Request Stroke
| GPRQSK
(wsid,
device,
length,
status,
view,
npoint,
pointarray) |
Purpose
Use
GPRQSK to have the graPHIGS API execute a
request to the specified stroke device.
The graPHIGS API returns a sequence
of World Coordinate (WC) points and
the view table index whose matrix
was used to convert the stroke locations to
World Coordinates (WC)
Stroke input is returned
from the view active for input with the highest input priority
that contains all the points.
View 0 is the highest priority view,
unless modified by your application.
Parameters
wsid -- specified by user, fullword integer
Workstation identifier.
device -- specified by user, fullword integer
Stroke device number (>=1)
length -- specified by user, fullword integer
Length of
pointarray provided by the application
for the graPHIGS API
to return stroke data (>=0)
This value is specified as the size of the
pointarray in
point entries.
status -- returned by the graPHIGS API, fullword integer
Status
(1=NONE, 2=OK
)
view -- returned by the graPHIGS API, fullword integer
View table index.
npoint -- returned by the graPHIGS API, fullword integer
Number of points returned in point array (>=0)
pointarray -- returned by the graPHIGS API, array of
short floating-point numbers (WC)
Coordinates (3D) of points in
stroke returned as a pointlist of
width=3.
