GRreqlutil/mgrltil

intn GRreqlutil(int32 ri_id, intn interlace_mode)

ri_id IN:

Raster image identifier returned by GRcreate or GRselect

interlace_mode IN:

Interlace mode

Purpose

Specifies the interlace mode to be used in the next palette read operation(s).

Return value

Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.

Description

GRreqlutil requests that the subsequent read operations on the palette attached to the image identified by the parameter ri_id, use the interlace mode interlace_mode.

The parameter interlace_mode specifies the interlace mode in which the data will be stored in memory when being read. Valid values of the parameter interlace_mode are MFGR_INTERLACE_PIXEL (or 0), MFGR_INTERLACE_LINE (or 1) and MFGR_INTERLACE_COMPONENT (or 2).

FORTRAN
