.. -*- mode: rst -*- ======== Pdfgrid ======== --------------------------------------------------------------------- Add a grid on top of all pages of a PDF document. --------------------------------------------------------------------- :Author: Dinu Gherman <> :Homepage: :Version: Version 0.2.0 :Date: 2009-06-07 :Copyright: GNU Public Licence v3 (GPLv3) About ----- *Pdfgrid* is a Python command-line tool and module for adding a regular grid on top of all pages of an existing PDF document. It will mostly be used for measuring individual parts of PDF pages like graphics or paragraph widths. For the time being, only a rectangular grid with major and minor lines is supported, and their colour and line widths can be set individually. NOTE: This is an initial release. The API is likely to change and for the time being the grid size is limited to A4, but this will change in future releases. *Pdfgrid* depends on two Open Source libraries, namely `pyPdf <>`_, a package written by Mathieu Fenniak and `reportlab <>`_ by ReportLab, Ltd. This version fixes an issue with the manual installation. Features -------- - add regular rectangular grid over all pages of a PDF document - define grid origin on all PDF pages - define grid styles containing grid step, line width and colour - use multiple grids at once with different styling - install a Python module named ```` - install a Python command-line script named ``pdfgrid`` - provide a Unittest test suite Examples -------- You can use *pdfgrid* as a Python module e.g. like in the following interactive Python session:: >>> from reportlab.lib.colors import red >>> from reportlab.lib.units import cm >>> from pdfgrid import grid >>> grid("foo.pdf", origin=(0, 0), styles=[(1*cm, 0.1, red)]) written: foo-grid.pdf In addition there is a script named ``pdfscript``, which can be used from the system command-line e.g. like this:: $ pdfgrid -h $ pdfgrid -v $ pdfgrid --origin "0,0" --styles "1*cm,0.1," foo.pdf written: foo-grid.pdf Installation ------------ There are two ways to install *pdfgrid*, either as a so-called Python *egg* via the ``easy_install`` command, if available on your system, or from a source tarball. Please see the seperate file ``INSTALL.txt`` for more detailed instructions! Dependencies ------------ *Pdfgrid* depends on *pyPdf* which, if missing, will miraculously be installed together with *pdfgrid* if you have a working internet connection during the installation procedure. If for whatever reason *pyPdf* cannot be installed, *pdfgrid* should still install fine. In this case you'll get a warning when trying to run *pdfgrid*. *PyPdf* also needs the `ReportLab toolkit <>`_ to be installed, which unfortunately cannot be installed yet as a Python **egg**. Testing ------- The *pdfgrid* tarball distribution contains a Unittest test suite in the folder ``src/test`` which can be run like shown in the following lines on the system command-line:: $ tar xfz pdfgrid-0.2.0.tar.gz $ python written: samples/test-a4-p-grid-default.pdf .written: samples/test-a4-p-grid-origin.pdf .written: samples/test-a4-p-grid-style.pdf .written: samples/test-a4-p-grid-styles.pdf . ---------------------------------------------------------------------- Ran 4 tests in 0.806s OK $ python running: pdfgrid --styles '10*mm,0,;50*mm,2,' 'samples/test-a4-l.pdf' written: samples/test-a4-l-grid.pdf . ---------------------------------------------------------------------- Ran 1 test in 0.482s OK Bug reports ----------- Please report bugs and patches to Dinu Gherman <>. Don't forget to include information about the version of your hardware platform, operating system, Python interpreter and, of course, *pdfgrid* itself.
