Briss 2.0

Briss is a small application to crop PDF files. It is useful for example to crop whitespaces at the edeges so text is rendered bigger on small screens like eInk displays or tablet PCs.

It helps the user to decide what should be cropped by creating an overlay of similar pages, e.g. all pages within a PDF having the same size or orientation. Even and odd pages are separated too.

Version 2.0 is intended to be a GUI Update for the Briss PDF cropping tool. It is based on Briss 0.9 which is located at sourceforge: http://sourceforge.net/projects/briss/

Briss is running on Windows, MacOS and Linux and works with Java 8 and above.

Installation

Currently Briss 2.0 is in alpha therefore some features are still missing (for example the page skip list). If you want to give it a try you can download the pre release from https://github.com/mbaeuerle/Briss-2.0/releases. There is a version of Briss for Java 8 and one version for any newer version of Java.

Usage

You can run the application by executing the following command in terminal (in Windows use Briss-2.0.bat):

./bin/Briss-2.0

or

./bin/Briss-2.0 cropthis.pdf

Commandline

If you prefer command line and trust the basic automatic detection algorithm use it this way:

./bin/Briss-2.0 -s [SOURCEFILE] [-d [DESTINATIONFILE]]

Example:

./bin/Briss-2.0 -s dogeatdog.pdf -d dogcrop.pdf
./bin/Briss-2.0 -s dogeatdog.pdf

the second line will create the cropped pdf into dogeatdog_cropped.pdf

To split according to columns/rows, respectively use the --split-col and --split-row arguments. For example:

./bin/Briss-2.0 -s dogeatdog.pdf -d dogcrop.pdf --split-col

Splitting columns will try to split the pdf into two columns. Splitting rows will try to split the pdf into two parts by cutting pages in half.
