GPCRC (wsid, ctid, model, length)

Purpose

Use GPCRC to create a color table with a specified color model and length for a specified workstation. All entries are initialized to the linear scale between the minimum and maximum values supported by the workstation.

This color table may be used for image processing. For information on using color tables for image processing see The graPHIGS Programming Interface: Understanding Concepts

Parameters

wsid -- specified by user, fullword integer

Workstation identifier.

ctid -- specified by user, fullword integer

Color table identifier (>=1)

model -- specified by user, fullword integer

Color model (1=RGB )

length -- specified by user, fullword integer

Length of color table in log2 (>0)
