yet another cropping tool

I recently sent kovid a set of patches which implemented a cropping tool for pdf's for the command line. It was released in yesterdays version Version 0.4.127. Basically you can use it to reduce the page by a set amount or use the output of ghostscript to automatically crop pages.

The usage is :

Code:
pdftrim --help
Usage: pdftrim.py [options] file.pdf

Crops a pdf. 


Whenever you pass arguments to pdftrim.py that have spaces in them, enclose the arguments in quotation marks.

Options:
  --version             show program's version number and exit

  -h, --help            show this help message and exit

  --verbose             Be verbose, useful for debugging. Can be specified
                        multiple times for greater verbosity.

  -o OUTPUT, --output=OUTPUT
                        Path to output file. By default a file is created in
                        the current directory.

  -x BOTTOM_LEFT_X, --leftx=BOTTOM_LEFT_X
                        Number of pixels to crop from the left most x (default
                        is 10)

  -y BOTTOM_LEFT_Y, --lefty=BOTTOM_LEFT_Y
                        Number of pixels to crop from the left most y (default
                        is 10)

  -v TOP_RIGHT_X, --rightx=TOP_RIGHT_X
                        Number of pixels to crop from the right most x
                        (default is 10)

  -w TOP_RIGHT_Y, --righty=TOP_RIGHT_Y
                        Number of pixels to crop from the right most y
                        (default is 10)

  -b BOUNDING, --bounding=BOUNDING
                        A file generated by ghostscript which allows each page
                        to be individually cropped [gs -dSAFER -dNOPAUSE
                        -dBATCH -sDEVICE=bbox > bounding]
Like all of calibre it is free under the gpl. As its part of calibre its not going to get horribly complicated but I hope it will be usefull

Thank you for your useful tool, it arrives at the right time - I need to trim out a "slice" from each page of a book I scanned.

I got the tool from the latest calibre install, so I don't know if the problem comes from the tool itself or from calibre, anyway here is the output:

> pdftrim -x 100 "Marazzini - La rilegatura artigianale e d'arte.pdf"

Traceback (most recent call last):
File "/usr/bin/pdftrim", line 8, in <module>
load_entry_point('calibre==0.4.127', 'console_scripts', 'pdftrim')()
File "build/bdist.linux-i686/egg/calibre/ebooks/pdf/pdftrim.py", line 56, in main
AttributeError: 'NoneType' object has no attribute 'title'


not knowing python, it's hard for me to decode the error...

thanks for any help!

I know what the problem is, so I will send a patch to kovid tonight and knowing him it will be out in the next patch.

If you can set a title and author on the source pdf that will probably fix the problem now.

I think I have fixed it in the next release, as kovid has commited the patch. If you want me to test it, attach the file to this thread.
