GRreqlutil/mgrltil

intn GRreqlutil(int32 ri_id, intn interlace_mode)

ri_id	IN:	General raster image identifier returned by GRcreate or GRselect
interlace_mode	IN:	Interlace mode of the next palette read operation: MFGR_INTERLACE_PIXEL (or 0), MFGR_INTERLACE_LINE (or 1), or MFGR_INTERLACE_COMPONENT (or 2)

Purpose	Sets or resets the interlace mode that will be in effect during the next palette read operation.
Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
Description	GRreqlutil can to called anytime before the palette read operation.
Example	This example illustrates the use of GRreqlutil:

     #include "hdf.h"

     int32 ri_id, pal_id, stat;
     VOIDP palette_data;
     intn interlace_mode = MFGR_INTERLACE_PIXEL;
       ...
     stat = GRreqlutil(ri_id, interlace_mode);
     stat = GRreadlut(pal_id, palette_data);
       ...
