filename	IN:	Name of the HDF file
	image	OUT:	Pointer to image buffer
	width	IN:	Number of columns in the image
	height	IN:	Number of rows in the image

	Purpose	Retrieves an image from the next 24-bit raster image set.
	Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
	Description	DF24getimage retrieves the image and stores it in an array. If DF24getdims has not been called, DF24getimage finds the next image in the same way that DF24getdims does.
		The amount of space allocated for the image should be width x height x 3 bytes.
		To specify that the next call to DF24getimage should read the raster image using an interlace other than the interlace used to store the image in the file, first call DF24reqil.

	FORTRAN	integer function d2gimg(filename, image, width, height)
		character*(*) filename, image
		integer width, height
