NAME

       empty-page - empty page detector of the ExactImage toolkit

SYNOPSIS

       empty-page [option...] {-i | --input} input-file

       empty-page {-h | --help}

DESCRIPTION

       ExactImage is a fast C++ image processing library. Unlike many other library frameworks it
       allows operation in several color spaces and bit depths natively, resulting in low memory
       and computational requirements.

       empty-page counts dark pixels of a black and white image and decides with a threshold
       whether the page is most probably empty, and thus can be removed from the image processing
       stream.

OPTIONS

       -i file, --input file
           Read image from the specified file.

       -m n, --margin n
           Set width of border margin to skip. For speed reasons, the margin has to be a multiple
           of 8. The default is 16.

       -p x, --percentage x
           Set fraction of permissible dark pixels. The default is 0.05 (5%).

       -h, --help
           Display help text and exit.

EXAMPLES

           $ empty-page -i test.tif
           The image has 75461 dark pixels from a total of 1060992 (7.11231%).
           non-empty

EXIT STATUS

       The exit status is 0 if the image is mostly white, 1 otherwise.
