Name

PSMLC − Returns the 2D coordinates of the locator position from the locator-class logical input device specified. 

Operating States: PHOP, WSOP, ∗, ∗
PHIGS standard function
 

Syntax

PSMLC (WKID, LCDNR, VIEWI, LPX, LPY)

Argument        Data Type      Access   Description
---------------------------------------------------------------------------
WKID            Integer        Read     Workstation identifier
LCDNR           Integer        Read     Locator device number
VIEWI           Integer        Write    View index
LPX, LPY        Real           Write    Locator position, in world
                                        coordinates (x, y)
---------------------------------------------------------------------------

Description

PSMLC takes the current measure of the locator-class logical input device specified by the device number and the workstation identifier.  The function returns the world coordinate point and the view index of the view transformation Digital PHIGS uses to translate the normalized projection coordinate point to the world coordinate point. 

Digital PHIGS uses the current workstation transformation to translate the device coordinate point to the normalized projection coordinate point.  See Getting Started with DEC PHIGS for more information about view indexes. 

This function ignores the z-coordinate components and returns a two-dimensional result.
