Zipping files and HTML5 File API - html

Is it possible to bundle files into a zip file using the File API, or another part of the HTML5 suite? If so, are there any example implementations available? If not, is this something likely to be supported by modern browsers in the next year or two?

I think this is what you might have been looking for. It's probably too late to help you, but I'll just leave this here for anyone else who might be interested.

While I don't know of anything built into HTML5 currently, I've seen some projects that are starting to touch on this in JavaScript. You may want to take a look at this project, which allows you to read the contents of a zip file, and if it's compressed using the Deflate algorithm, can unzip them.

Another option which works really well with plain javascript is a zip API called sendzip. It allows you to create zip file on the fly and streaming it to users.

How do I open a directory using Html when the files and html are all on a DVD

I work for a large company with agents all over the U.S. We want to upgrade our agents to Open Source office suite (Apache Open Office) from the chaotic mismatch of different versions used now. Problem is many of our people are barely computer literate.
I need to build a menu in Html to install the proper version on their systems from a DVD I have downloaded the files onto.
I can code some Html and some java but not a lot. It would help if it were cross browser since some use Macs but most use PCs.
I have researched for days and find many references to no access from the Web bit surely there is a way to do it offline?
Thanks in Advance.
I'm not sure that HTML is really what you want here. HTML is used to create web pages, but it's not a programming language and is not well suited to executing commands or performing tasks. JavaScript is the most common programming language used in web browsers, but you will have problems accessing a user's local file system for security reasons.
The best option I can think of is to give the installers appropriate names based on OS, and include documentation that clearly explains to users what they need to do. HTML may or may not be suitable for the documentation depending on your needs.
I want to thank everyone for their help.
Do to time restraints I believe the fastest solution is to do a simple text document in several forms describing the file choices and links to the files.
This way may not be eloquent but it is efficient.
Thanks for your time.

XSLT from the web - Needing the right dev/test environment

Mostly for learning and testing-purposes, I need an environment/software where I can apply XSL Transformations on websites (html).
It needs to support Sessions and Cookies because of a login required to actually reach the pages I want to transform via XSL.
The manual method aka calling the page in the browser and download it and copy into Eclipse for example, is too slow. I need an automated system.. if possible one which can call multiple pages via a script.
I know that this could be realized with a lot of coding in Java, but I hoped for a simpler solution...
Any ideas?
Thanks in advance!
No clue why people have downed this question -_-', but I've found a sufficing solution:
Using "wget" for downloading the files and Saxon HE (NET) for actually applying the transformations. Those programs can be easily called from windows CMD :)

Is there a way to export PSDs using AS3

Plead/Preparing for standard SO backlash
This is a generic question I apologize as I'm not an SO "noob" and I realize this doesn't fit the format exactly, if you can suggest a better place for this query I'm all ears. If you choose to down vote or close please suggest an alternative.
Question
Is anyone aware of projects that already generate a PSD file from within AS3?
Background (everything below here you may not care about if you just want to answer a question, but if interested I could use a hand)
I've found an AS3 PSD parser here.
For some basic tests this has worked fine (after some tweaking to avoid errors). However, now the task is to reverse this process to write a PSD file.
Current plan (and overall goal)
I also found a file format specification document.
My plan at this point is to just start from the top and work my way through the document building each of the parts of the file (and helper value objects) as I go along. Since this will be a very time consuming process, I'm wondering if there's any other previous work I could build off of.
Ultimately my goal is to integrate this code into a mobile drawing project I've been working on for some time. Since it's a mobile project I have to deal with the possibility that the OS kills my app to reclaim memory, in that case I need to be able to save/load the existing state of the app (currently has layers of BitmapData similar to photoshop, plus would be cool to be able to open PSD files and open my files from the device in photoshop with layers preserved).
Links to live version and code
The app can be downloaded here (is free will remain free, no ads, app is funded by love and the desire to create something cool everyone can have/use):
Google Play
Amazon App Store
Still working on an iOS release (process is more involved than the other two stores)
The code can be found here on github (Flash Builder project files in the FlashBuilderProject/FingerPainting folder).
Legal
Essentially the code contained in that repository is all MIT or Apache Licensed (will be going back to double each of the authors sites to get the original licenses to copy in now, just in case). I'm not a lawyer, but I believe I legitimately obtained everything in the project currently and am simply obligated to include the licenses and make my extensions of the source code available in some cases. (fonts came from google web fonts and downloaded Roboto from Google directly http://developer.android.com/design/style/typography.html). Any code in the com.shaunhusain package I wrote and you can assume is GPL for now. If anyone more legally savvy wants to tell me I'm breaking the law, and how, I would appreciate it.
The portions included and used from other sites include
Actuate MIT License
PNGEncoder2 License included in source from Adobe permits usage.
ShareANE I don't have a license for this one (he didn't include one) the author is chinese, as such I'm having some difficulty figuring out how to contact him, but am assuming I'm safe to use his code.
A couple of pieces of code are in the repository but currently not used including a GIF parser/encoder from bytearray.org and a ColorMatrix class from Grant Skinner.
Update
After trying this for a while I ended up deciding to just use the ORA format since it is open and far far simpler and works fine with GIMP and Krita (open source editors).
I'm not sure about the intended use, but if you are compiling the file in Flash, you might be able to use JSFL to export the fla to a PSD. Then tie the JSFL functionality to a button in a SWF that you load as a panel in the IDE. JSFL is pretty powerful, however it only works within the IDE/locally.

How to merge multiple PDF's in native ActionScript?

I am looking for a solution to this issue but I have not yet found anything conclusive. I would love to get some input. What I need to do is basically to take two or more individual PDF-files and merge them into one. Nothing fancy just sticking one after the other and ending up with one file.
I have found AlivePDF and purePDF but those libs both seem to be focused towards generating PDF's from scratch.
I would greatly appreciate any input on this. Thx.
I don't know how you can merge PDF files on the client side, but if nothing is left over (and the files aren't too large) you could send them to the server. There you have the choice between your favorite PDF merge tool or library (e.g. PDFBox).
You can't merge PDFs in AS3.
The best you can do is load PDF files and do minor javascript scripting of the HTMLLoader (AIR only) instance into which the PDF is loaded. See Known limitations for PDF content in AIR for more.

Seeking a compact format for HTML ebooks for offline reading under Linux

I have a netbook running Linux and a large collection of computer books and reference material as HTML. I'd like some compact way of storing these books which can be browed without unpacking them first. This would save space and reduce wear on my small SSD.
If there was some way to convince Firefox to browse files contained in ZIP file, this would be ideal. (I know iCab (Mac) had a web archive format that worked this way.) Perhaps a Firefox plugin? A small web server that can serve directly from ZIP files? Some magic FUSE module? Does anyone have any ideas?
On my PDA (which the netbook is largely replacing) I used iSilo for this, but it's not available for Linux, its conversions are lossy and it costs money.
There is the FUSE zip thing here :
http://code.google.com/p/fuse-zip/
Gvfs should also support zip files.
Calibre might help (convert to a compressed format, manage, view e-books).
You can use OpenOffice.org to open the html pages, and then save them as OO documents. OO documents are essentially a zip files.
Another option is to use OO to save as pdf.
You can even do this from a command line using this OO macro.
Same with AbiWord - you can use it on commandline to convert.
In the AbiWord example there is shown how to convert all files in a directory to a desired format (pdf). Then you can use pdftools to merge all pages in one document.
Also, I do not know what windows manager your laptop has, but if it is KDE, konqueror (the file and web browser for KDE) opens web pages from inside a zip file w/o any problem.
Most probably Gnome's Nautilus can do this as well (I have no Gnome here to test).
Have you ever tried to open a zip file with whatever file manager you have, and then click on a web page inside it?
