I am making a website to capture image ID. I am using webcam.js How can I put a frame on camera when it is accessed on mobile web browser and crop the area outside the frame to focus only on the captured ID? I cannot find any documentation on webcam.js. Please help me. Thank you

I'm creating a mobile web application (HTML5/JavaScript/CSS only) that allows a user to take a picture. The picture from the camera is then loaded into a canvas HTML element. The user may rotate their phone when taking a photo so ultimately I want to rotate the output appropriately. Is there a way in a web page only to determine which degree a user has rotated when taking a picture? I'm not simply talking about whether they are in landscape mode. I'm meaning if you hold your phone straight up in portrait mode face it down at your desk (its now parallel with your desk) and then rotate it to landscape. This will not trigger an orientation change, but you will now be holding your phone in a "landscape" position if that makes sense. This will be a common way users will be taking the photos. I want to be able to rotate the image appropriately when uploading it.
Thank you

Yes there is! When photos are taken, they contain metadata - information about the image. This is called EXIF data.
It tells you things like the make of camera, whether the flash went off, and - usefully for you - the orientation of the camera.
If you are using JavaScript to draw the image onto the canvas, I can recommend BlueImp's JavaScript Load Image Library
Once you have loaded the image, you'll be able to do a call like:
var orientation = data.exif.get('Orientation');
That will tell you which way the camera was held when the photo was taken. Depending on the phone, you may also get rotation data, GPS data, compass heading, etc.
I'm having a hard time finding any data on how to detect the color of an image taken from a phone's camera using adobe air. The idea is that the user takes an image and then the app (that uses this code) detects the color of the item the user has photographed by placing a cursor on top of it.
So does someone please tell me how is this attainable in adobe air and action script 3.
many thanks in advance!!!!
You can use getPixel or getPixel32 from BitmapData() enter link description here
Than you can convert it to HEX if you wish.

You are trying to overlay a lightweight Swing component on top of a heavyweight AWT Canvas.
Use:

Is it possible to move the playbar into a custom position on a slide not connected to the borders?
My company wants to migrate to captivate and we need to position the controls on a certain position in our slides, such as in the frame of the course.
Needs to be html5 compatible as well if that makes any difference.
Thanks
you can manipulate the playbar using javascript, which you can set to execute when the first slide loads.
playbar.style.marginTop = "20px" will push it down a bit for example
I'm a begginer, and I need your help :)
I have a simple landing page, made from one long jpg + image mapping.
I've embedded a youtube video in a specific location on the image as an object command but I want to show a different image until it is pressed (an image with a play button, for example).
The page will be shown on a facebook tab as well.
Can any1 help me?
P.S - Sorry if I have grammar mistakes :)
Thanks!
Pretty sure a placeholder can be implemented via the Youtube API or you could take a look at this, How to add a splash screen/placeholder image for a YouTube video
Using JavaScript: You could add a Listener to the image so once it is pressed it loads a video.
var image = new Image(); //Image with playbutton
//Then load your Video in the EventListener
image.onclick("load", function() {
alert("loaded");
The function() method will contain the code to run your video
This is a good link about EventListeners http://idratherbewriting.com/javascript/events-and-listeners-javascript/
