I need to create a firefox plugin that allows a user to take screenshots of any part of their desktop and have them uploaded to a server. There seems to be lots of plugins for screen capturing a webpage, but nothing for capturing anything outside of firefox. So after a little research I have not found much information on how this might be possible. I don't want to resort to a using a java applet but I will if that is my only option.
Does anyone have advice on how I might create such a feature?
Thanks
I don't think a Firefox addon is the most appropriate approach here. Maybe split the task into a Firefox addon to offer the "upload to a server" component and a native app to do the desktop screenshot (or just integrate with existing screenshot tools).
If you're worried about complicating the installation process for end users, you could look into bundling the addon component and native app into a single installer (e.g. MSI on Windows, RPM on Linux, etc.). You'll have to come up with different apps for each platform you want to support (and maybe even each version - e.g. Windows XP vs Windows 10).
Whatever you decide, you'll probably need to create a more specific question to get further help here (there's no simple Firefox.Addons.API.TakeScreenShot() answer I'm afraid).
Also make sure you're using the right terminology - a plugin is the deprecated NPAPI approach whereas addons are still supported.
I'm actually working on taking native desktop screenshots just in the last coupel of days. I'm using js-ctypes. My work goal is the same exact thing to, upload to server. If you would like to collaborate I am very open to it! We can chat about it on #jsctypes irc channel :) irc://moznet/jsctypes (Mibbit IRC WebApp) If you don't know js-ctypes thats ok i can handle that while you can handle uploading techniques, and an editor on canvas :) The editor is a huge part of it, you can see my ideas/plans here: https://github.com/Noitidart/NativeShot/wiki/NativeShot
I'm really really interested in a collab on this!
I'm still working on windows right now, the color is messed up: https://github.com/Noitidart/NativeShot/tree/digitanks-method
I was just about to start OSX work following this example here: https://developer.apple.com/library/mac/samplecode/SonOfGrab/Introduction/Intro.html and here: Take ScreenShot without Window
You can install the addon from that branch and click the icon that gets added to the toolbar, it will take a screenshot with 3sec delay and then append it to the body of the selected tab. (Windows only right now)

Got some quirks. Released it as v1.0 though. I'm working on Android support, pretty close. I need to flesh out the editor tools. Please let me know if you're willing to collaborate.
dear experts: we would like to publish a magazine in epub format, so that it can be read on iPads. (our creation system is now multimarkdown -> specialized post-processor -> calibre .) the problem is that our magazine needs math. this is not a problem on the epub viewer in ubuntu, as invoked by calibre. it invokes mathjax just fine. however, transfering the epub to a (net-connected) ipad (open in ibook) does not execute mathjax to display the equation. eventually, I also want this to work in android tablets, but for now, ipads are our only target. (iphones are too small for us, anyway.)
I do not want to graphically render the content, because I have never seen this look nice.
is there any way to create an ebook with mathjax for an ipad? the best choice would be if there were a way to get ibooks to execute javascript? if not, is there a tool that makes an app with ebook-reader-like functionality from html5 (incl javascript)? (does the javascript need to be local, or can it be web-connected?) if not, then what?
sincerely, /iaw
You can use MathJax in iBooks if you include a (slimmed down) MathJax installation within the ebook itself. This is not a great solution, but it can be made to work. See this article for some tips on how to do it. It is a little out of date, but I think it should still work.
In terms of preprocessing, which I know you don't want to do, you could use MathJax to generate SVG versions of the mathematics, which look pretty good on iOS, and should render on other platforms as well, so that might be a viable option for you.
I have posted a short script in
https://tex.stackexchange.com/questions/154644/eqnarray-math-to-svg?noredirect=1#comment353540_154644
that is a start for converting inline mathjax into inline svg. this should work in any epub and remove the mathjax dependency. it still has baseline problems, but it's a start. it rescales. hopefully someone else will pick it up and make it more robust.
For a school project i need to write or use a online programming editor. It is a part of a bigger project. I thought of a java application, php/html/javascript or flash.
I have a couple of things i could do:
Find a good working application and edit it so it works with the rest of the project
Find good parts for a editor and make it working my self (syntax highlighter, auto-indent, autocompletion, etc.)
Combination of those two
Does anybody know a good editor or have tips for this project or a editor?
Thanks for reading,
Leon
For the syntax highlighting and basic editing part, check out my recent question Textarea that can do syntax highlighting on the fly?
Solutions presented there:
CodeMirror
Bespin (Mozilla only, but great)
For the rest - autocompletion etc. - ... Check out the Wikipedia article Comparison of JavaScript-based source code editors
Interested to see what other suggestions come up.
Bespin comes to mind. Though it might be too bleeding edge, depending on how the rest of the project is built/meant to be used (but hey, programmers love bleeding edge).
If you decide to use PHP/HTML/CSS/JavaScript, see GeSHi for syntax highlighting.
I have a side project developed with ACE.
It connects to your server through SFTP and allows you to create new files,read and edit all from your browser with your file tree at sidebar.
Demo at TePe
Code at Github Repo
I found Cobalah Editor it's also built on CodeMirror but with some customization. There are some themes available we can set, increase or decrease font size.
What solutions are there for working on a LaTeX document on both Windows and Linux?
It's a large document, and I will be working daily on both platforms so compatibility is essential if it's two different pieces of software.
Bonus points for a solution that includes easy previewing.
Writing text is not very different from writing software. Similar management techniques apply when scaling up.
Modularity: Split the document to smaller pieces e.g. a separate .tex file for each chapter. I also like to keep the preamble and other LaTeX set-up separate from the body text. My chapter files themselves just have the body text with some markup but do not define any new commands.
Source control: Keep all the source files in a version control tool such as subversion. Transfer files between systems using the tool.
Builds: Have a Makefile or similar to control the build process: it should be consistent and repeatable. Build regularly and fix build problems as soon as possible. If you want easy previews, you can set up a Makefile rule to launch e.g. a PDF viewer after the target PDF has been compiled.
Editing: Use whatever you're compatible with. It does not matter that much, though some good advice has been given by other answerers.
Communication: If there's more than one person working on the same stuff, no tool is a substitute for interpersonal communication.
TeXworks is a new cross-platform TeX editor with a built-in PDF preview that has source-output synchronisation. Click in the source to go to the matching part in the output, and vice versa. It's not the most feature-rich editor, by design, but the simplicity/power trade-off is just right, in my opinion.
I've used Emacs and its AucTeX mode, which is great for editing, as it has a set of very consistent shortcuts to insert many common commands and environments. There are also preview modes that display maths graphically in the Emacs window but I haven't used them.
As with VIM, there's a learning curve of course.
Unlike Legoolas, I'd advise for direct-to-PDF compilation using pdfTeX, but maybe Windows/Linux doesn't have a PDF viewer that automatically reloads the file? I'd be surprised if so (I use Skim on Mac). Check if your viewer supports synctex, as it's quite handy to navigate from PDF to source and back, without the cons of pdfsync.
To compile, my tool of choice is latexmk which is included in TeXlive. It completely automates the build, and can watch the .tex source to rebuild automatically.
Try LyX – The Document Processor, a "What You See Is What You Mean" editor for LaTeX.
Eclipse with its TeXlipse plugin should solve the IDE problem. More important are, however, issues like using only fonts that are available or installable on both platforms.
For previewing I am using Emacs with its Preview Latex feature in the AucTeX package.
For windows, you can use the TeXnicCenter, that is one of the best IDE for windows.
For Linux, you can use simply use Kile (it is possible to use kile with KDE on CygWin, but it is not the perfect solution).
There is no problem to switch from one IDE to another one (since you just save the .tex file and nothing else)
It also exists some cross-platform IDE, but I do not know them:
TeXmaker
TeXmakerX: a fork from TeXmaker
Since you'll probably not want to change text editor from whatever you usually use just for editing LaTeX docs (unless you use an editor which can't do syntax highlighting for LaTeX as well as whatever else you code/write in it), I'd recommend the simple following set of tools:
Whatever text editor you are used to, as long as it can highlight LaTeX markup. If it can't, then find a better editor for using with everything you do!.
Install MikTeX or TeXLive and just use the DVI viewer which comes with them by double-clicking on your DVI file. This will automatically update whenever the dvi file is changed by your editing of the latex file and re-creating the output.
I use Emacs as my text editor of choice, on both Linux and Windows. Setting up some scripts or makefiles to build the latex document when I hit a key is pretty easy, and fits in with everything else I use Emacs for nicely.
Other cross-platform options (many of which have already been mentioned by others in this thread):
LyX
TeXlispse for Eclipse
I've used VIM, combined with the VIM-LaTeX plugin, with great success. It does have a bit of a learning curve though.
Gummi is the best LaTeX editor. It is a free, open source, program written in python, featuring a live preview pane.

Get your work in some kind of version control system, then when you move from computer to computer you just update from a central server and its just like you left it.
It doesn't matter about the IDE, as you are saving just the .tex file, as noted above. If you want to use the same editor though, for the sake of coherency, use texmaker.
I use version control, and just use MikTex/WinEDT on Windows and TexShop on the mac.
IF your document doesn't compile on both, you're probably forgetting to keep the two directories synchronized or use funky commands, I like the sanity checks of knowing that it "compiles" cleanly on two platforms.
I use some text editor, and then I have a cron job that does a compile hourly from my source control.
Tex files are just text. I would recommend using a version control system (you should be using that anyway) to keep the source in sync. You can then use any (or different) editors on each system, e.g. Kile for linux and winEdt for windows. Both com with nice viewrs.
For a simple solution for the source control that just works with minimum knowledge and hassle, consider dropbox.
Revisiting my own question after quite a few years, I thought I'd add

not strictly what I had in mind, but have used it for collaborative writing
An excellent multiplatform LaTeX IDE is Texmaker.
For Debian or Ubuntu, I made a tutorial easy to follow: Install LaTeX on Ubuntu or Debian. This tutorial explains how to install LaTeX on Debian or Ubuntu and how to create your first PDF.
Is there are any open source or free-ware library to display PDF file in my Delphi program?
I had looked for one, but most of them are commercial or not fully functional.
PS: this solution need to be cross platform by using wine.
One possible solution might be to include the open source SumatraPDF viewer with your program and use it to display the pdf's.
http://blog.kowalczyk.info/software/sumatrapdf/index.html
One nice thing about SumatraPDF, other than it being open source, is that it doesn't require an install. It consists solely of a single .exe, so you could just stick the .exe in your app's folder and call it to display pdf's. SumatraPDF is a pretty bare-bones viewer, so it may be one of the ones you've already looked at and rejected as "not fully functional", but I'm not sure whether you're going to find any perfect open source solution.
As others brought up in the similar thread that was linked from this one, you might consider using the Gnostice library or the WPCubed wpdfviewer component. You have to purchase a developer's license for those, but then can incorporate them in your app and deploy as many as you want with no runtime licensing fees.
My answer to this question discusses the Adobe API.
I missed the PS. Some other answers to the same question may help.
