NAME

empty-page - Empty page detector of the ExactImage library

SYNOPSIS

empty-page [-i|--input INPUT] [-m|--margin MARGIN] [-p|--percentage PERCENTAGE]

empty-page --help

DESCRIPTION

ExactImage is a fast C++ image processing library. Unlike ImageMagick, it allows operation in several color spaces and bit depths natively, resulting in much lower memory and computational requirements. Some optimized algorithms operate in 1/20 of the time ImageMagick requires, and displaying large images can be as fast as 1/10 of the time the "display" program takes.

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

OPTIONS

-i|--input INPUT
Input file.
-m|--margin MARGIN
Border margin to skip.
-p|--percentage PERCENTAGE
Coverate for non-empty page.
--help
Displays help text and exits.

EXAMPLES

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