The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE COLOR MODEL FACILITIES (PHOP,*,*,*)

Purpose

Use Inquire Color Model Facilities to inquire the list of available color models and the default color model on the specified workstation.

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameters. If the information is unavailable, then the values returned in the output parameters are unpredictable and the graPHIGS API sets the error indicator to one of the following errors:

2
Function Requires State (PHOP,*,*,*)
52
Workstation Type Not Recognized By Implementation
51
Information Not Available For Generic Workstation Type
59
Specified Workstation Does Not Have Output Capability
62
This Information Not Available For MO Workstation Type

Language Bindings

C

pinq_colr_model_facs (ws_type, num_elems_appl_list, start_ind, err_ind, models, num_elems_impl_list, def)

Input Parameters

Pint ws_type
Workstation type.

Pint num_elems_appl_list
Number of elements in the application list (>=0).

Pint start_ind
Starting index (>=0).

Output Parameters

Pint *err_ind
Error indicator.

Pint_list *models
List of color models (1=PMODEL_RGB, 2=PMODEL_CIELUV, 3=PMODEL_HSV).

Pint *num_elems_impl_list
Number of elements in the implementation list.

Pint *def
Default color model (1=PMODEL_RGB, 2=PMODEL_CIELUV, 3=PMODEL_HSV).

FORTRAN

PQCMDF (wtype, n, errind, ol, cmod, dfcmod)

Input Parameters

integer wtype

Output Parameters

integer errind
Error indicator.

integer ol
Number of available color models.

integer cmod
nth available color model (1=PRGB, 2=PCIE, 3=PHSV).

integer dfcmod
Default color model (1=PRGB, 2=PCIE, 3=PHSV).

Errors

None
