NAME
     dmSetImageDefaults, dmImageFrameSize - parameters for digital-media
     images

SYNOPSIS
     #include <dmedia/dmimage.h>

     DMstatus dmSetImageDefaults
           ( DMparams* params,
             int width,
             int height,
             DMpacking packing )

     sizet dmImageFrameSize( DMparams* params )

DESCRIPTION
     dmSetImageDefaults sets up a parameter list with all of the necessary
     parameters to describe an image for the digital-media libraries.  The
     parameters that are set and their values are:  DMMEDIUM = DMIMAGE,
     DMIMAGEWIDTH = width, DMIMAGEHEIGHT = height, DMIMAGERATE = 15.0,
     DMIMAGECOMPRESSION = DMIMAGEUNCOMPRESSED, DMIMAGEINTERLACING =
     DMIMAGENONINTERLEAVED, DMIMAGEPACKING = packing, DMIMAGEORIENTATION
     = DMBOTTOMTOTOP, DMIMAGEPIXELASPECT = 1.0.

     dmSetImageDefaults returns DMSUCCESS if there was enough memory
     available to set up the parameters, and DMFAILURE if not.

     dmImageFrameSize takes an image parameter list and returns the number of
     bytes needed to store an uncompressed image in that format.


EXAMPLE
              DMparams* imageParams;
              if ( dmParamsCreate( &imageParams ) != DM_SUCCESS ) {
                  printf( "Out of memory.\n" );
                  exit( 1 );
              }
              if ( dmSetImageDefaults( imageParams,
                                       320,  /* width */
                                       240,  /* height */
                                       DM_PACKING_RGBX ) != DM_SUCCESS ) {
                  printf( "Out of memory.\n" );
                  exit( 1 );
              }
              printf( "%d bytes per image.\n",
                      dmImageFrameSize( imageParams ) );
              dmParamsDestroy( imageParams );
