GPR_$INQ_BITMAP_PROJ_FORMAT GPR Calls GPR_$INQ_BITMAP_PROJ_FORMAT
NAME
gpr_$inq_bitmap_proj_format - returns the projection format for the
specified bitmap.
FORMAT
gpr_$inq_bitmap_proj_format (bitmap, projform, status)
DESCRIPTION
This routine returns the projection format for the specified bitmap.
Input Parameters
bitmap
The descriptor of the bitmap, in gpr_$bitmap_desc_t format. This is
a 4-byte integer that uniquely identifies the bitmap.
Output Parameters
projform
A pointer to the projection format, which is in gpr_$proj_format_t
format. This data type is a record in Pascal, a structure in C, or
an array in FORTRAN. The projection format specifies which set of
planes of the bitmap is active.
status
Completion status, in status_$t format.
NOTES
Use this call to find the current projection format for the display bit-
map.
The concept of projections is only applicable to display bitmaps.
To set the projection, call gpr_$initialize.
To change the projection, call gpr_$allocate_projection.
