While this question is asking for a downloadable documentation in general, I'm currently trying to find a good way to print the official Play framework documentation. My problem is that the whole documentation (available online) is split into small chunks of information and printing the whole documentation would mean hundreds of print jobs, each wasting a significant amount of paper. Is there some way to convert the whole documentation in a single/compact printable format? This would make a nice holiday reading :).
Apparently PDF documentation disappeared since Play version 2.1.0, I can see that is still available in 2.0.x if this satisfies you...
Anything I can advice is making a static copy of the pages so you can read it with some smartphone or tablet.

User needs to parse native-pdf(selectable data, not scanned, no OCR required) in local. The pdf files may be over 400 pages with large tables. Some tables may not have clear borders. Is there any API I could use?
Thanks!
Now that I know you don't want an API, I might recommend that you check out ItextSharp, from nuget. I have used this several times in the past, and there are many stack overflow forums on how to use it. https://www.nuget.org/packages/iTextSharp/5.5.13.1
EDIT: I apologize, it looks like iTextSharp has been replaced with iText 7 https://itextpdf.com/en/products/itext-7
It seems there are several PDF parser APIs out there you could use. PDFTron looks promising, and they offer a free trial: https://www.pdftron.com/pdf-sdk/parsing-library/
DocParser may also be helpful for you, https://docparser.com/features.
I found all of these through a simple google search, so it may benefit you to do some research for yourself. As we can only make broad suggestions based on the information in your question.
My goal is as follows: I have to read in a video that is stored on the sd card, process it frame for frame and then store it in a new file on the SD card again，In each image to do image processing.
At first I wanted to use opencv for android but I did not seem to be able to read the video
here.
I am guessing you already know that doing this on a mobile device or any compute limited devices is not ideal, simply because video manipulation is very computer intensive which translates to slow execution and heavy battery usage on many devices. If you do have the option to do the processing on the server side it is definitely worth considering.
Assuming that for your use case you need to do it on the mobile device, then OpenCV on Android will now allow you to read in a video and access each frame - #StephenG mentions this in his answer to the question you refer to above.
In the past, functionality like this did not get ported to the Android OpenCv as the guidance was to use ffmpeg for frame grabbing on Android devices.
According to more recent documentation, however, this should be available for Android now using the VideoCapture class (note I have not used this myself...):
http://docs.opencv.org/java/2.4.11/org/opencv/highgui/VideoCapture.html
It is worth noting that OpenCV Android examples are all currently based around Eclipse and if you want to use Studio, getting things up an running initially can be quite tricky. The following worked for me recently, but as both studio and OpenCV can change over time you may find you have to do some forum hunting if it does not work for you:

Taking a different approach, you can use ffmpeg itself, in a wrapper in Android, for tasks like this.
The advantage of the wrapper approach is that you can use all the usual command line syntax and there is a lot of info on the web to help you get the right parameters.
The disadvantage is that ffmpeg was not really designed to be wrapped in this way so you do sometimes see issues. Having said that it is a common approach now and so long as you choose a well used wrapper library you should at least have a good community to discuss any issues you come across with. I have used this approach in a hand crafted way in the past but if I was doing it again I would use one of the popular examples such as:

I am playing around with Leadtools to see how it might benefit me but i am a little frustrated with their documentation regarding how the process works. I am creating a library with methods that take an input file, convert it to pdf, add a qrcode to the file and save it and then reading the qrcode again.
Does a pdf have to be converted to an image before leadtools is
able to read the qrcode?
Does leadtools allow converting from
doc to pdf and then adding the qrcode or do i have to convert it to
an image as well?
Is there anywhere I could look at code
samples of how I can go about doing what I talked about other than
the leadtools site itself?
I am sorry to hear that you are having difficulties, but I will do my best to get you pointed in the right direction.
To answer your questions:
A1.) Yes, the PDF will need to be rasterized before the LEADTOOLS barcode engine can be used. Our barcode engine will only work with raw image data. Once the file is decompressed into raw data, we will not access the file any further.
A2.) Yes, you can rasterize Microsoft Word documents using either our file I/O methods or with the LEADTOOLS Virtual Printer. Once you have the raw image data, you can pass it to the barcode engine to write the QR code into the data. Once the barcode is written, you can then compress the image into any supported format, including (raster) PDF. You can also create a searchable PDF by running the resultant image through an OCR engine & outputting to PDF.
A3.) The LEADTOOLS SDK has a main barcode demo that should illustrate the ability of the SDK to handle the features you describe here. There are also tutorials in the help file, and various projects on our support forums. We have also created a couple different CodeProject articles here:
Multi-Platform Barcode with LEADTOOLS 18
How to Read Barcodes from Images using LEADTOOLS
You haven't mentioned here what programming language you are developing with or what the specific problem are that you have encountered. Without knowing either of those, it's difficult to get more specific into any methods or other resources to check out. For a simple raster conversion of a Microsoft Word Doc to PDF and writing a barcode, I think this would probably take between 10-15 lines of code.
If you have not already, I would highly recommend sending an email to Support#leadtools.com or open a live chat with the LEADTOOLS Support team from LEADTOOLS.com. We can get into more specifics there and help you more directly with any issues you are encountering.

I tried adding this as a comment, but it is apparently too long for that. So I have added it as another answer.
Even if you are building a DLL, I would suggest starting out building a simple demo with a view of the image so you can see what exactly is happening to the image. Once you are comfortable that the image is being modified the way you want, then implement that code in your own library.
Also, I would recommend testing out the toolkit with the provided main demos. The demos are there to illustrate the different options you have access to in the code. If you can accomplish what your application or library will need to do through the demos, then it would be worth your time to begin coding specifically what you need. You might even need to use multiple demos to verify the tools can accomplish the goals that you have. You have all the toolkit code for the demos, so you can take them apart and use the specific pieces that you need in your application.
If you are having trouble identifying which demos to try out or whether the toolkit has the specific functionality that you need, your best bet is to contact Tech Support directly to ask. We are here to help get you pointed in the right direction.
To get down to brass tacks, the source of the image data is not all that important from the perspective of the barcode engine. It needs a RasterImage handle (raw image data) to write the specified barcode. Whether the image data is created on the fly, read from file, or generated from a scanner, it does not make a whole lot of difference.
To find the main .NET barcode demo, I would start out by going to the LEADTOOLS shortcuts. To get there, go to the Start menu -> LEADTOOLS -> Help and Demos. The shortcuts are broken down by programming language, feature, and then the base toolkit. You should be able to find the WinForms .NET barcode demo here:..\Shortcuts.NET Class Libraries.NET Framework\01 Imaging\07 Barcode
Our toolkit example is a .NET WinForms project, but it will work in ASP.NET also.
Here are some links to tutorials if you want to dig right into the code:
Loading and Displaying an Image in WinForms
Reading Barcodes
HOW TO: Load and Display an Image with WebImageViewer
There was also this recent code tip posted illustrating how to read and write UTF-8 characters in a QR barcode.
We provide both .NET 2.0 and .NET 4.0 DLLs for our barcode engine. Both of these work within Visual Studio 2012.
I recently watched great google talks speech about Cling - C++ language interpreter. But I wonder if anyone except people at CERN (where it is developed) are using Cling, and how good it is from non-collider-physics-scientist point of view, can you write desktop apps with it?
There are some videos of uses cases different from the High Energy Physics: http://www.youtube.com/results?search_query=cling+c%2B%2B (I think first couple are the relevant ones)
It has the potential to be very useful, but it is very young. There is no documentation that I could find, no dedicated mailing list, no online tutorials. I was able to get small toy code to run, but couldn't figure out how to use it productively on a large library yet.
Cling project is well established one. You can find more information in their official website cling. They also have a forum
Thanks
Where can I find the documentation for IdocScript for Stellent/Oracle UCM? I just got assigned to do maintenance on a page that uses it, and have no prior experience with either Stellent or the script. My specific problem has to do with string manipulation, but I can hardly find any documentation online at all, odd for a programming-related topic.
If you are after a book, there is the one by Brian Huff (Bex - http://bexhuff.com/) linked below.
Actually it is the only one. Written before Oracle bought Stellent and may be a missing some IDOC changes.
As a resourse tho it is very handy to have around as it touches on all things UCM (including a decent chunk on IDOC).
The Definitive Guide to Stellent Content Server Development
~ Brian Huff
Of course I answered my own question 15 minutes after I asked it. Oracle has a guide buried deep in its documentation website. It's available as a PDF or in HTML format (thanks, Raystorm).
