I need to capture the currently active web page as a screenshot. I've already tried html2canvas & GrabzIt but the problem is that I need a precise screenshot of the page I am on currently. The reason why I don't want to use html2canvas is because it does not always return a good version of a screenshot (not rendering properly) and I don't want to use GrabzIt because it's not free.
Do any of you have an idea how to accomplish this either by using javascript/java/flash?
Any option will do as long as it works...
P.S. I'm currently capturing screenshots with my addon for Firefox by using the function that firefox offers : context.drawWindow and now i want to make it available online.
Thanks a lot!
Currently possible alternatives:
rasterizeHTML.js:
this tool looks to be capable to capture a while page containing sophisticated html-structure and an image as well in this demo:
http://cburgmer.github.io/rasterizeHTML.js/
Lively 3D:
On the tool's website you can find a demo as well and it is still supported and developed.

HTML2Canvas:
Or after all HTML2Canvas because it does not look like that it is put on hold, quite the opposite there is a new release-version of it. And since I used it it might be handle rendering images onto a canvas better.

Old-Answer:
I used this package in one of my projects and it worked pretty well. The only complain I have to make on this package is that images are not rendered that well in the final screenshot. But may be it's improved since then.
In the end, I ended up using server side generation of screenshots with phantomjs. Found it the most reliable in my scenario and it takes pretty decent screenshots.

Is possible to capture a screenshot of a specific element or portion of the rendered page using capybara-webkit?
This can be easily accomplished with Capybara + Poltergeist (phantomjs driver), since it offer a non standard save_screenshot(path, selector) method.
Looking at capybara-webkit documentation we can see the options parameter for the #save_screenshot. But digging deeper, I found only width and height examples.
I need for instance, capture a screenshot displaying only a rendered img element during Capybara session. And that image is available at the bottom of the page.
This is possible using capybara-webkit? How?
Any help will be much appreciated.
Mission accomplished.
For those interested, I solved the issue using the imagemagick CLI:
session.save_screenshot(temp_file_path)
system("convert #{temp_file_path} -crop <width>x<height>+<left>+<top> +repage #{temp_file_path}")
I'm sorry, I skipped over the part where it says "of a specific element or portion of the rendered page", so the answer below is for screenshots in general.
You can save the current HTML by calling save_and_open_page.
Depending on what you want to accomplish, this might be way better than a screenshot or of no use at all...
On drivers that support it, there's also page.save_screenshot('screenshot.png')

This may be a very basic question, but is it possible to post a jsfiddle that captures a Rails environment, the js, css, and HTML that is generating a nagging problem? I posted another SO question here: Unable to float a twitter bootstrap navbar item right with either class=pull-right or float:right
... and it was suggested I post something to jsfiddle. Honestly, I'm just completely in the dark as to how I might gather the css, js, and HTML in a way that can be copy-pasted into jsfiddle. Is there some slick way to pull the 4 necessary components together?
I am mostly interested in being being able to share and debug code that pertains to display and layout.
Many thanks in advance.
Sites like jsfiddle and jsbin are useful as testbeds for various issues involving HTML, CSS, and JavaScript. A good workflow for using them might be as follows:
Before going to one of those sites, use a browser debugger (Firebug, the Chrome debugger, or even the debugger in modern versions of IE if you must) to figure out the mechanics of the issue. Are you seeing unexpected JavaScript behavior? Weird layout? Whatever the problem, see if you can narrow the focus as much as possible.
Now, go to one of the workbench sites (make an account for yourself too; it helps to be able to find old experiments) and start trying to reproduce the problem. Start as simply as possible and work up. It can be hard and frustrating, but in my experience even the process of trying to figure out an isolating test case can itself lead to enlightenment :-)
If you do manage to isolate a behavior that you don't understand or can't explain or whatever, you can then save the test case (jsfiddle has "Save" and "Update" buttons; jsbin seems to magically save things automatically) and then post the URL here (or anyplace else). If you do post here, it's a good idea to copy the relevant code from your test case directly into your question.
I use both of those sites (and there may be more of them out there). The jsbin site gives you a little more control over your page, and provides a way to see your page outside of an <iframe>. That's kind-of important if you're testing for mobile applications. Otherwise they're both great resources.
Oh, and both sites let you import various popular libraries via simple configuration tools. That's really handy for tracking bugs that you think may have been introduced by a library version change (rare, but really freaky when it happens).
I want a single online web page for my bookmarks. The page should include small windows which opens the following pages:
Fizy, Facebook, Guardian.
There should also be a button for adding a new window with an URL text input.
Here's an illustration of how the page should look: http://i54.tinypic.com/2hrkb48.jpg
I've built a version of this at http://bit.ly/heqEd1, but as you may see, it uses iframes under javascript windows, which can not open frame-breaking sites (like fizy.com), or Facebook.
I'll make the research and but I am not sure how to proceed. Any solution will be accepted, like HTML5, XUL, Flex, AJAX or others. A solution with a local installation(like a Firefox extension) is not preferred, but still be ok.
Note: Piro Sakura has built a Firefox extension called split-browser. There's an element of the project called "subbrowser". An AJAX window that can show a subbrowser MAY solve the problem. I know the page will only be available from Firefox, but that is ok. (Again, a solution without an installation is preferred)
Any suggestions? How should I proceed? What should I learn? Is this possible?
Thanks.
I think you should use a Javascript with iFrames to do this. I'm not too sure what you're trying to accomplish with this, but it should be possible. As for which framework you'll use, it's up to you, but there will be a lot of custom code needed to implement this.
You can make multiple draggable windows in FLEX same as you have in you app
Please check sample as Starting point Movable/Draggable window and its demo
also u knows JS-DESKTOP lib with little customization to achieve that one of them are
jsdesk
sonspring-JQuery based
also you can do this using
Hopes that helps
What's the smallest lightbox plugin for jQuery (in terms of size)? Something close to Fancybox, but smaller :)
I wrote a low-level jQuery lightbox script called Nitelite: https://github.com/premasagar/nitelite (it's 1.4KB when minified and gzipped)
It is the kind of thing that can be either used on its own, or to build more feature-rich lightbox plugins.
It's been used in production on a couple of projects:
the BBC World Service widget (click a news article): http://www.bbc.co.uk/persian/services/2009/05/090512_pm_widget_conditions.shtml
the MiShorts widget (click a film thumbnail): http://www.mishorts.com/widget
It's open source, MIT license. Enjoy ;)
I have used this sometime ...
http://www.digitalia.be/software/slimbox2
It's only 4K .
As Yi Jiang already stated, the "smallest" depends completely on your specific needs, if you want everything that Fancybox does, I hardly doubt that there's a way around using that very plugin.
Still you could take a look at others and see whether they fit your needs, you should check out this list of lightbox scripts, many of which are smaller in size than Fancybox, but you'll still have to evaluate them and see if they fit your needs.
And last but not least you can always write your own one by reading a tutorial. That is, if you want to write your own one. But then again, if you have such specific needs you should know that nobody will come along and write some code for you for free.
My approach to these sort of problems is to find a script that meets my requirements then hack it mercilessly until it only contains what I need. Once that's achieved, I'll minify the script (leaving the compression of the script up to my server).
While we're on the subject, if you are looking for small scripts mainly to reduce the browser fetch time, then also ensure that your web server cache control headers and compression settings are set to good values. A nice writeup (regarding caching) can be found here. If you don't have a good caching policy defined, then it won't matter much whether the script is small if it is being downloaded from the server on every page view.
I would shy away from the PrettyPhoto plugin, which appears convenient. There is an advertisement on their demo which is suspicious (my site was redirected shortly after experimenting with it)
If you are looking for a lightbox, try to find one that has been updated to the latest query. Slimbox2 and fancy box have not been updated for modern css, using images to build the box, and neither have been updated for streamlining changes in the latest jquery.
My web site uses 16 x 16 pixel icons (stored on the server as PNG files). I'd like to provide functionality for users of the site to edit these icons. My site already uses jQuery and jQuery UI, and I'm familiar with these, but any suggestions would be welcome.
EDIT
It seems that this is harder than I thought. I think I'm going to hold off trying to incorporate this functionality into the web site. But if anyone knows of a JavaScript icon/bitmap editor not already mentioned in the thread, please let me know.
Check out http://www.jpie.net/ (requires PHP as well), it's the most advanced thing I've found but not too sure how much actual 'editing' users need to do (or can do on a 16px image...)
This is what you need: 100% javascript, great clean code.

Is the perfect start. With some work you can make it fit exactly as you need.
HIH,
You can get some inspiration here

I don't know of any licence-free, ready-to-go editor though.
