A SANE image is a rectangular area. The rectangular area is
subdivided into a number of rows and columns. At the intersection of
each row and column is a quadratic pixel. A pixel consists of one or
more sample values. Each sample value represents one channel (e.g.,
the red channel). Each sample value has a certain bit depth. The bit
depth is fixed for the entire image and can be as small as one
bit. Valid bit depths are 1, 8, or 16 bits per sample. If a device's
natural bit depth is something else, it is up to the driver to scale
the sample values appropriately (e.g., a 4 bit sample could be
scaled by a factor of four to represent a sample value of depth 8).
So the answer is yes.
