NAME
empty-page - empty page detector of the ExactImage toolkitSYNOPSIS
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 fileRead 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.SEE ALSO
