can be displayed with a "fade in" effect in a browser.

the browser does not have to wait for the entire image

``gray_scale_depth`` specifies the number of shades of gray by how
many bits of gray scale information is used per pixel. The larger
the number of bits per pixel, the larger the resulting file.
Options are: * **0**: On/Off One bit per pixel using an
on/off strategy. All background pixels are made white (on),
and all foreground pixels, black (off). This setting
creates small files and is good for images with lots of
background, such as line plots and contour lines. *
**1**: 1 Bit per Pixel One bit per pixel using gray scale
values of pixels to determine black or white. Those
pixels that are more than 50 percent gray are black; the
rest are white. This setting creates small files that might
be useful for a rough draft or a preview image. *
**4**: 4 Bits per Pixel Four bits per pixel resulting
in sixteen levels of gray scale. This setting generates
fairly small image files with a fair number of gray levels.
This setting works well for most preview image purposes. *
**8**: 8 Bits per Pixel Eight bits per pixel resulting in
256 levels of gray. This setting is useful for full image
representation, but the files generated by this setting can
be large.
(default: `None`)
byte_order (`TIFFByteOrder`, optional) Specify the byte order
