Description

pinq_marker_facs queries the workstation description table and returns values for the following:

•Number of available marker types

•List of available marker types

•Number of available marker sizes

•Nominal marker size in device coordinates

•Range of polymarker sizes (maximum, minimum) in device coordinates

•Number of predefined polymarker indexes

If Digital PHIGS returns 0 as the number of available marker widths, the workstation supports a continuous range of marker sizes.
