Parameters ---------- fname : str or file-like object Name of destination file. arr : ndarray of uint8 or float Array (image) to save. Arrays of data-type uint8 should have values in [0, 255], whereas floating-point arrays must be in [0, 1]. format_str: str Format to save as, this is defaulted to PNG if using a file-like object; this will be derived from the extension if fname is a string kwargs: dict Keyword arguments to the Pillow save function (or tifffile save function, for Tiff files). These are format dependent. For example, Pillow's JPEG save function supports an integer ``quality`` argument with values in [1, 95], while TIFFFile supports a ``compress`` integer argument with values in [0, 9]. Notes ----- Use the Python Imaging Library. See PIL docs [1]_ for a list of other supported formats. All images besides single channel PNGs are converted using `img_as_uint8`. Single Channel PNGs have the following behavior: - Integer values in [0, 255] and Boolean types -> img_as_uint8 - Floating point and other integers -> img_as_uint16 References ---------- ..
