float* read_tiff_rgba_f32	(	const char *	fname,
		size_t *	nx,
		size_t *	ny
	)

load the data from a TIFF image file as a float RGBA array

The array is allocated in this function call. It hold the RGBA pixels as 4 contiguous arrays.

Parameters:

	fname	the file name to read
	nx,ny	storage space for the image size

Returns:

the data array pointer, NULL if an error occured
