GPQCF - Inquire Color Facilities

GPQCF (wstype, errind, model, ncolor, avcolor, npred)

Note:

This subroutine is a Workstation Description Table (WDT) inquiry. For an overview, see "WDT Inquiries"

Purpose

Use GPQCF to inquire the color facilities of the specified workstation type.

The graPHIGS API returns the default color model of the workstation (model[default] the total quantity of available colors (ncolor[default] the color status (avcolor) where 1=MONOCHROME, 2=COLOR and the quantity of predefined color table entries in the workstation's default color table (npred)

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameter. If the inquired information is unavailable, then the error indicator (errind) contains the error number indicating the reason, and the values returned in the output parameter are unpredictable.

Parameters

wstype -- specified by user, 8-byte character string

Workstation type.

errind -- returned by the graPHIGS API, fullword integer

Error indicator. If the error indicator is zero, the request has been completed. Otherwise, one of the following errors exists:

23: SPECIFIED WORKSTATION TYPE DOES NOT EXIST
35: WORKSTATION HAS ONLY INPUT CAPABILITIES
548: SPECIFIED WORKSTATION TYPE CANNOT BE LOADED

model -- returned by the graPHIGS API, fullword integer

Color model of the workstation (1=RGB, 2=HSV, 3=CMY, 4=CIELUV )

ncolor -- returned by the graPHIGS API, fullword integer

Number of available colors (the total color palette size)

avcolor -- returned by the graPHIGS API, fullword integer

Color available (1=MONOCHROME, 2=COLOR )

npred -- returned by the graPHIGS API, fullword integer

Number of predefined default color table entries.
