NAME

       im_initdesc - initialises an image descriptor to specific values

SYNOPSIS

       #include <vips/vips.h>

       void im_initdesc( IMAGE *image,
            int xsize, int ysize,
            int bands, int bandbits, int bandfmt,
            int coding, int type,
            float xres, float yres,
            float xo, float yo )

DESCRIPTION

       im_initdesc(3)  initialises  the  image  descriptor  according  to  the
       entered values.  More specifically the Xsize,  Ysize,  Bands,  BandFmt,
       Coding, Type, Xres, Yres, Xoffset and Yoffset members of the descriptor
       are initialised by the correspondingly entered arguments.  The  members
       fd,  baseaddr, data and filename are not handled by this function.  The
       order of the args is the same as in vips/vips.h.

       The bandbits parameter is deprecated and ignored by this function:  you
       can always pass zero.

       Example: make a 512 by 512 one-band memory buffer.

          if( !(im = im_open( "temp", "t" )) )
               /* Error ...
          im_initdesc( im,
              512, 512,
              1, 0, FMTUCHAR,
              NOCODING, B_W,
              1.0, 1.0,
              0, 0 );
          if( im_setupout( im ) )
              /* Error ...
