Detailed Description

read numbers from vil_stream

Functions to read integers and floats from a vil_stream. The endianness refers to the format in the stream, not the native format of the compiler or execution environment.

    Modifications
     Peter Vanroose, July 2000: corrected serious bug: VXL_LITTLE_ENDIAN not needed
                         (implementation was wrong for VXL_BIG_ENDIAN machines)
     Ian Scott, May 2003: rearrange explicit io, to allow for easier expansion.
     Peter Vanroose - 23 Oct.2003 - Added support for 64-bit int pixels

Function Documentation

float vil_stream_read_big_endian_float ( vil_stream * is )

Reads in a 4-byte big-endian float.

void vil_stream_read_big_endian_int_16	(	vil_stream *	is,
		vxl_uint_16 *	data,
		unsigned	n
	)

Reads in n 16 bit unsigned ints.

Caller is responsible for allocating enough space.
