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.
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.
