NAME

DoMarkerScale − Create a marker scale factor primitive attribute object

SYNOPSIS

C:

DtObject DoMarkerScale(scale)
DtReal scale;

Fortran:

INTEGER∗4 DOMS(SCALE)
REAL∗8 SCALE

DESCRIPTION

DoMarkerScale creates a marker scale factor primitive attribute object.  The parameter scale specifies the relative size of the image of polymarker primitive objects.  The actual size of the displayed marker is determined by multiplying the marker scale factor by a device-dependent nominal marker size; the result is in frame units.  Polymarkers are represented by single points until rendering, and thus have no dimension (or scale) until the marker glyph is used.  The parameter scale may be any floating point number; negative numbers will invert the maker representation in X and Y.  If the parameter scale is 0, the marker will be a single point.  The same result can be achieved with less overhead using the marker glyph DcMarkerPoint <DCMKPT>. 

DEFAULTS

The default DoMarkerScale is 1.0.
