GRreqimageil/mgrimil

intn GRreqimageil(int32 ri_id, intn interlace_mode)

ri_id	IN:	General raster image identifier returned by GRcreate or GRselect
interlace_mode	IN:	Interlace mode to be in effect during the next image operation: MFGR_INTERLACE_PIXEL (or 0), MFGR_INTERLACE_LINE (or 1), or MFGR_INTERLACE_COMPONENT (or 2)

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

     #include "hdf.h"

     int32 ri_id, stat;
     intn interlace_mode = MFGR_INTERLACE_PIXEL;
     int32 start[2], stride[2], edge[2];
     uint16 data[100];

     start[0] = start[1] = 0;
     stride[0] = stride[1] = 1;
     edge[0] = edge[1] = 10;
       ...
     stat = GRreqimageil(ri_id, interlace_mode);
     stat = GRreadimage(ri_id, start, stride, edge, data);
       ...
