I am going to developing an application, which is an epub. I have PDF files. I need to make those files as reflowable content(epub)... Then only the PDF files will be viewable in mobiles, tablets... etc.. Please suggest the solutions to make reflowable contents from the PDF...
If you don't mind using an open source software, go with Sigil.
If you want to learn innards of how to create by hand, or some tool of your own, Follow this. (This is a one month course, So you will not get all the content in one day, though).
Create the folder structure.
In a folder of your choice, create the following: META-INF (folder), OEBPS (folder), mimetype ( a file with exactly same name ).
Put application/epub+zip in the file mimetype. No spaces no lines.
Convert your PDF to text format. In Adobe acrobat, you will have file > export> .
Read the content from PDF, you will find some conclusions of how you can split them in to chapters or sub reading topics. Split according to the understanding of the book, and make so many text files.
Make sub folder structure. Make Images, Text, Styles (folders) content.opf, toc.ncx (files) inside OEBPS folder.
Put all your split files in Text folder created in step 5.
put all images extracted in pdf in Images folder
Put any styles (not describing here,) in Styles folder.
In the META-INF folder created in step 1, create a file called container.xml and fill with the following: <?xml version="1.0"?><container version="1.0" xmlns="urn:oasis:names:tc:opendocument:xmlns:container"> <rootfiles> <rootfile full-path="OEBPS/content.opf" media-type="application/oebps-package+xml"/> </rootfiles></container>.
If you are able to do these many things sincerely, ping again, I would try to tell you what you should put in content.opf, and toc.ncx in created in step 5.
As an example, You can use some example from my site. Download from here and use them with caution. Do not distribute.
We're opening up a beta for our web based pdf reflow viewer at the beginning of 2015. Feel free to sign up to be part of our beta test. More info here:

Can you change the location of 'rst' files in sphinx without changing their URIs? I'm working on a documentation where we want to move some files to different folders, without changing the URIs:
For Example: If you create a sphinx project with $ sphinx-quickstart and add some files and folders:
index.rst
/tutorials/howToFoo.rst
/scripts/
With the toctree in in index.rst looking like that:
.. toctree::
:maxdepth: 1
:caption: Processing:
:glob:
scripts/*
tutorials/*
Then after building the project with make html, you have a link in your browser as seen here: tutorials/howToFoo.html
If you want to save the the file in a different folder:
index.rst
/tutorials/
/scripts/howToFoo.rst
Then the URL of your file howToFoo.rst changes depending on where it is saved:
scripts/howToFoo.html.
This is a problem because I don't want links to tutorials or scripts to break.
As the project aims to include many people, it will be very probable that there will be changes in the file structure in the future.
Now my question: Can you create a setup where you can move the files without having to write redirects to their new location, every time you move them?
For Cross Referencing inside of Sphinx this is solved for example with targets, explained here:
https://docs.readthedocs.io/en/stable/guides/cross-referencing-with-sphinx.html#automatically-label-sections
But this doesn't help me because the link in the browser still stays the same.
What I want is a link SomeNeverchangingLinkFor_howToFoo.html regardless of where the file howToFoo.rst is saved.
With the use of the Open XML SDK 2.0, I did preformed the Reflected Code of an Excel file.
Along with other things, the Excel file has some images in some of the cells. When I run the code that was generated, the file show the images just fine.
What I need to do is to programatically inject images in place of the
images that are there now. The thing is, I cannot find where the images are at in the code that was generated. How can I figure this out? Also what is the easiest way to replace those images with new ones programmatically?
You may want to take a look at a similar question about inserting images into Excel files with OpenXML SDK: C# & OpenXML: Insert an image into an excel document.
Basically, those files are created as separate document parts. The answer I linked to should show You how to insert a new image into a document, however, in order to substitute existing images with your custom ones, you could probably just modify the binary data of appropriate ImagePart (and some other associated properties).
If You need some help with the code performing this task, let me know.
I like to have a main page Web part with a link to each one of the shared documents in our portal.
The problem is that they are from different libraries and also I want the SharePoint to keep track of check in and check outs of the files. When I use, Content Editor to add the links, and then click on the list, it download a copy of file and saved changes do not change the original document.
I thought about creating a modified view in that specific library and filter out just one file. Then put that file in the front page. But, the first problem is that the file is 2 or 3 level deep in hierarchy. Also, even if I manage to do that, what should I do about different files in different libraries?
Please Advise
Does anyone have some sample code demonstrating how to make a "file browser" view? I'd like to be able to navigate through directories and drill-down the sub-directories and see files located within the various folders. I want the user to be able to create new directories/files and even select an existing file. Is there sample code out there already available to do this?
I don't know about sample code, but this wouldn't be too complicated to achieve using NSFileManager and a UITableView.
You can obtain arrays of directory contents using the subpathsOfDirectoryAtPath:error and associated methods of a file manager. These arrays in turn can populate a UITableView. It would be fairly easy to put together a navigation controller that could display a series of table views showing a file hiearchy.
Bear in mind, however, that you'll only be able to access the directories inside your application sandbox, unless you're running on a jailbroken device.
The iOS programming guide says that
You should never present users with the list of files in this directory and ask them to decide what to do with those files. Instead, sort through the files programmatically and add files without prompting.
This is assuming you are trying to implement file browse feature for your documents directory.
I'm an author of FileExplorer which is a file browser for iOS and fulfills most of your requirements.
Here are some of the features of my control:
Possibility to choose files or/and directories if there is a need for that
Possiblity to remove files or/and directories if there is a need for that
Built-in search functionality
View Audio, Video, Image and PDF files.
Possibility to add support for any file type.
You can find my control here.
I am trying to develop an iPhone application to read ePub files. Is there any framework available to develop this? I have no idea about how to read this file format. I tried to parse a sample file with .epub extension using NSXML Parser, but that fails.
The EPUB format brings together a bunch of different specifications / formats:
one to say what the content of the book should look like (a subset of XHTML 1.1 + CSS)
one to define a "manifest" that lists all of the files that make up that content (OPF, which is an XML file)
one to define how everything is packaged up (OEBPS: a zip file of everything in the manifest plus a few extra files)
The specs look a bit daunting but actually once you've got the basics (unzipping, parsing XML) down it's not particularly difficult or complex.
You'll need to work out how to download the EPUB, to unzip it somewhere, to parse the manifest and then to display the relevant content.
Some pointers if you're just starting out:
parse xml
unzip
To display content just use a UIWebView for now.
Here's a high level step by step for your code:
1) create a view with a UIWebView
2) download the EPUB file
3) unzip it to a subdirectory in your app's documents folder using the zip library, linked above
4) parse the XML file at META-INF/container.xml (if this file doesn't exist the EPUB is invalid) using TBXML, linked above
5) In this XML, find the first "rootfile" with media-type application/oebps-package+xml. This is the OPF file for the book.
6) parse the OPF file (also XML)
7) now you need to know what the first chapter of the book is.
a) each <item> in the <manifest> element has an id and an href. Store these in an NSDictionary where the key is the id and the object is the href.
b) Look at the first <itemref> in the <spine>. It has an idref attribute which corresponds to one of the ids in (a). Look up that id in the NSDictionary and you'll get an href.
c) this is the the file of the first chapter to show the user. Work out what the full path is (hint: it's wherever you unzipped the zip file to in (3) plus the base directory of the OPF file in (6))
8) create an NSURL using fileURLWithPath:, where the path is the full path from (7c). Load this request using the UIWebView you created in (1).
You'll need to implement forward / backward buttons or swipes or something so that users can move from one chapter to another. Use the <spine> to work out which file to show next - the <itemrefs> in the XML are in the order they should appear to the reader.
Apparently EPUB is "just" an XML format, so if you have an xml parser and the spec it should be okay.
Plus a little tuto? Have fun!
EDIT: you could also read some code here, this is for generating epub, not reading them but the code may be useful.
EDIT again: And see links to related question in the right sidebar, there are some links in the answers to free ebook reader which support ePub.
EDIT 3: You should add a comment when you edit your question so people who answer you can continue the discussion (if you don't comment we're not noticed of your edit).
So, The parsing fail because you didn't read the spec or related questions on Stack Overflow... *.epub file are a zipped folder containing XML file(s), not plain xml.
I read through this tutorial once (free registration required, sorry) and it gave me a great introduction to ePub. deverloperWorks tutorial here
I highly suggest you look at some of the XML processing libraries. If you just want to get specific information out of the XML file, then you can pick the right parsing strategy.
there is an open source project fbreader,
it also support iphone
http://www.fbreader.org/about.php
I'm playing arround to create an epub-framework for iphone apps.
At the moment (I really just startet) i can generate a title page with links to the chapters.
My approach is
Use quickconnect iphone framework as
a layer (maybe i change to phonegap)
which basically allows for javascript
apps as iphone apps
Add the UNZIPed epub as a ressource to the project
Parse the whole thing with a customized version of the epub.js (somewhere on google-code)
Right now I'm looking into pageflip, some kind of gui and minor usability issues (save the current page beingviewed)
I hope that give's you an idea on how to start
Jonathan Wight (schwa) has developed a ObjC solution for parsing and displaying ePub documents on the iPhone. It's part of his TouchCode open source repository.
