Returns the number of available bitplanes.
FORTRAN (libfgl.a)
Int32 getplanes( )
INTEGER*4 GETPLA
The getplanes subroutine returns the number of active bitplanes that are currently being used for drawing. The number returned depends on how the frame buffer has been configured. In particular, the returned value depends on the most recent setting of the drawmode subroutine, whether the system is in single or double buffer mode, whether it is in color map or RGB mode, and finally, on the capabilities of the installed adapter.
Note: This subroutine cannot be used to add to a display list.
The number of bitplanes available under the current drawmode.
The example C language program scrn_rotate.c uses the getplanes subroutine to get the number of bitplanes available.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
