BINARY:
BINARY - Black and white image, suitable for 1-bit compression.
ANTIALIASED:
ANTIALIASED - When the source image is a document photo, this mode
will produce nice, smooth, antialiased text in grayscale, which is typically more readable
than the text in BINARY mode. Antialiasing requires extra processing,
which makes this mode slower than BINARY mode.
Output mode of binarization filter.
