SET POLYLINE LINETYPE
This operation sets the linetype for subsequent polyline operations. The total
number oflinestyles available is device-dependent; however 5linestyles are required
- one solid plus four dash styles.
If the requested linestyle is out of range then linestyle 1 (solid) should be used.

This operation sets the width oflines for subsequent polyline operations. The width
is specified in Device Coordinates (DC).

This operation sets the color index for subsequent polyline operations. The color
signified by the index is determined by the Set Color Representation operation. At
. least two color indices are required. Color indices range from 0 to a device-
dependent maximum.
