I'm trying to use the LibreOffice SDK to convert a .doc file in a .docx one.
Unfortunately in my project I can't use the LibreOffice commands and call from cmd:
libreoffice7.0.3 --headless --convert-to docx --outdir /u/user/doc_folder /u/user/doc_folder/old_office/file.doc
so I need to use directly the SDK.
The problem is that the doc seems not to be very clear or probably I'm not searching well.
In this link there is the Developer Guide and in particular, in the "Desktop Environment Example" section there is a Desk example, which should shows how to convert a file.
However, the example code doesn't show anything of this. (link to the example code)

I'm trying to download my Jupyter notebook as a PDF from the web interface by going to:
File -> Download as -> PDF via LaTeX
However, I get this error:
nbconvert failed: pdflatex not found on PATH
I have both pandoc and MacTex installed. Additionally, in the terminal the pdflatex is set.
$ which pdflatex
/Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin/pdflatex
I'm running on Mac OS X El Capitan using Jupyter 4.2.0 with Python 2.7.11
Print it to pdf using your browser (ctrl+p). It is simple and the "you print what you see" approach is great to share a reports/analysis with people that do not code or use the jupyter enviroment. Not publication ready by any means but gets the job done. Just make sure your plots and figures are not on interactive mode otherwise they will not be displayed (set them to %matplotlib inline).
I always had trouble with exporting my jupyter nb to pdf through latex. Quick search and you see that A LOT of people do. I could get some stuff worked out but the formatting was lackluster with code and plots not displayed the way I wanted. I eventually accepted that the jupyter notebook could not produce "publish-ready" pdfs easily. When I want that, I generate plots/figures/code on jupyter and call them on a latex file.
You may want to hide some of your code from the pdf, set the resolution of your plots and add some extensions to improve your jupyter documents.
If you really want to make your publications from inside jupyter, this tutorial has some great tips.
I've had a lot of luck exporting to HTML instead of pdf. HTML is similarly viewable by any non-developers in your organization, assuming they have a browser, and you can make use of some excellent tools like toc2, which gives your viewers a table of contents so they can stay oriented with what they are reading. You can also link to specific sections using the "#" symbol to do header links. Similarly, HTML supports interactive plotting like those available through plotly, so that end-users can zoom into graphs and other figures. Encourage you to give it a shot. Example code with nbconvert below:
jupyter nbconvert --to html --template toc2 --TemplateExporter.exclude_input=True "<path-to-ipynb>"
If its really necessary to have a pdf, you can then open your html in Chrome or Firefox and print to pdf that way. Hope it helps!
I wanted to use nvd3 examples that are live on their website: http://nvd3.org/livecode/#codemirrorNav
What should I do? The example link has multiple tabs, should I copy paste and save all those codes in one folder and open it an index.html ?
I would download their source and use the examples in their examples folder, as it's tidily set up for you to manipulate.
Source: https://github.com/novus/nvd3 (either clone or download as a .zip)
PS I would use Firefox to open them as Chrome can be really testy about using files locally and not from a webserver.
I'm trying to batch convert a bunch of assorted iWork files (Numbers, Pages, Keynote) to PDF on the command line.
I've been trying cups-filter but there's no MIME type filter for the iWork types. I then looked into using qlmanage to generate the preview image and use that, but this doesn't seem to work for multi file Keynote documents as they generate as HTML rather than PDF.
Any suggestions? I'd rather not resort to AppleScript.
I created an .applescript script that converts all .pages files within a folder to .docx. .pdf support can be easily added. In pages2docx.applescript you just need to replace Microsoft Word with PDF.
Here's what I ended up going with, since I really wanted to avoid, AppleScript.
When saving an iWork document there's a "Include Preview In Document" checkbox. Checking this creates a "QuickLook/Preview.pdf" inside the iWork document bundle (which is actually a zip file). Luckily I had this checked for most of the zip files, so it was simply a case of unzipping to NSTemporaryDirectory and grabbing that file.
For those that didn't I put together a script to run qlmanage to create the document preview. For some that creates the PDF, for others it creates an HTML file. You can then use http://code.google.com/p/wkhtmltopdf/ to convert this HTML to a PDF.
Well... you need something that
understand the iWork file formats,
can render the documents to then create the PDF.
Unless you want to re-invent the iWork suite... Sounds simpler to just tell the iWork apps what you want from them.
You would do that via the Scripting Bridge
I would use Applescript, but perhaps you can use Ruby and Python with the Scripting Bridge to accomplish what you need
With Scripting Bridge, RubyCocoa and PyObjC scripts can do what AppleScript scripts can do: control scriptable applications and exchange data with them.
I haven't used the Scripting Bridge in a while, but I believe you can tell applications to print documents. And any application that can print in OS X can send it to PDF instead.
Here are a couple of commands to help those who want to get this working without much thought. It worked for me with a ppt file.
Make sure to get wkhtmltopdf from here.
qlmanage -p -o /tmp /path/of/file.ppt
wkhtmltopdf /tmp/file.ppt.qlpreview/Preview.html /output/to/file.pdf
You may have to fiddle with sizes if you want the original pages to stay consistent, for the ppt I was using the following parameters did the job:
wkhtmltopdf --page-width 200 --page-height 145 Preview.html file.pdf
Edit: I have written a Python script to do a batch conversion. Hopefully people can contribute to make it more robust:

How can I create the preview image for MS Office files like word, excel, power point in cocoa. Can anyone suggest me on this like how to handle those file? I tried using the Bitmap representation of the .doc files. It didn't work. Which API I can use?
It sounds like you want to use Quick Look. There is a great example of using Quick Look to generate an NSImage you can display anywhere with this code from Matt Gemmell
Look inside the snippets/QuickLook folder in the ZIP file he links to, and you'll find his code for getting the Quick Look preview for any file. Leopard and Snow Leopard can preview most Office files out of the box without needing Office to be installed.
I would like to convert pdf, doc files to html files using Cocoa
Please help me in this.
Thanks in advance,
You can convert Word files to HTML using NSAttributedString. You can't do this in pure Cocoa for PDF files; you'll have to use a conversion tool, such as stigi suggested. To do that, use NSTask.
Cocoa's PDFKit framework can convert a PDF file to text, through PDFDocument's -string method for example. Of course this won't copy images or formatting though, and it depends on PDFKit being able to recognize text in the file.
there are a couple of tools for the unix commandline that do such kind of conversions.
check out http://pdftohtml.sourceforge.net/ & http://rtf2html.sourceforge.net/
you may see if there are other tools like this.
but to get back to your question. these command line tools can be called from within your cocoa app (won't work on the iphone) and produce the html result.
check out this link for a guide on how to embed such command line tools within your app.
