GNU LESSER GENERAL PUBLIC LICENSE |
||||
Version 3, 29 June 2007 |
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
||||
Everyone is permitted to copy and distribute verbatim copies |
||||
of this license document, but changing it is not allowed. |
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates |
||||
the terms and conditions of version 3 of the GNU General Public |
||||
License, supplemented by the additional permissions listed below. |
||||
|
||||
0. Additional Definitions. |
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser |
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU |
||||
General Public License. |
||||
|
||||
"The Library" refers to a covered work governed by this License, |
||||
other than an Application or a Combined Work as defined below. |
||||
|
||||
An "Application" is any work that makes use of an interface provided |
||||
by the Library, but which is not otherwise based on the Library. |
||||
Defining a subclass of a class defined by the Library is deemed a mode |
||||
of using an interface provided by the Library. |
||||
|
||||
A "Combined Work" is a work produced by combining or linking an |
||||
Application with the Library. The particular version of the Library |
||||
with which the Combined Work was made is also called the "Linked |
||||
Version". |
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the |
||||
Corresponding Source for the Combined Work, excluding any source code |
||||
for portions of the Combined Work that, considered in isolation, are |
||||
based on the Application, and not on the Linked Version. |
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the |
||||
object code and/or source code for the Application, including any data |
||||
and utility programs needed for reproducing the Combined Work from the |
||||
Application, but excluding the System Libraries of the Combined Work. |
||||
|
||||
1. Exception to Section 3 of the GNU GPL. |
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License |
||||
without being bound by section 3 of the GNU GPL. |
||||
|
||||
2. Conveying Modified Versions. |
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a |
||||
facility refers to a function or data to be supplied by an Application |
||||
that uses the facility (other than as an argument passed when the |
||||
facility is invoked), then you may convey a copy of the modified |
||||
version: |
||||
|
||||
a) under this License, provided that you make a good faith effort to |
||||
ensure that, in the event an Application does not supply the |
||||
function or data, the facility still operates, and performs |
||||
whatever part of its purpose remains meaningful, or |
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of |
||||
this License applicable to that copy. |
||||
|
||||
3. Object Code Incorporating Material from Library Header Files. |
||||
|
||||
The object code form of an Application may incorporate material from |
||||
a header file that is part of the Library. You may convey such object |
||||
code under terms of your choice, provided that, if the incorporated |
||||
material is not limited to numerical parameters, data structure |
||||
layouts and accessors, or small macros, inline functions and templates |
||||
(ten or fewer lines in length), you do both of the following: |
||||
|
||||
a) Give prominent notice with each copy of the object code that the |
||||
Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
4. Combined Works. |
||||
|
||||
You may convey a Combined Work under terms of your choice that, |
||||
taken together, effectively do not restrict modification of the |
||||
portions of the Library contained in the Combined Work and reverse |
||||
engineering for debugging such modifications, if you also do each of |
||||
the following: |
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that |
||||
the Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
c) For a Combined Work that displays copyright notices during |
||||
execution, include the copyright notice for the Library among |
||||
these notices, as well as a reference directing the user to the |
||||
copies of the GNU GPL and this license document. |
||||
|
||||
d) Do one of the following: |
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this |
||||
License, and the Corresponding Application Code in a form |
||||
suitable for, and under terms that permit, the user to |
||||
recombine or relink the Application with a modified version of |
||||
the Linked Version to produce a modified Combined Work, in the |
||||
manner specified by section 6 of the GNU GPL for conveying |
||||
Corresponding Source. |
||||
|
||||
1) Use a suitable shared library mechanism for linking with the |
||||
Library. A suitable mechanism is one that (a) uses at run time |
||||
a copy of the Library already present on the user's computer |
||||
system, and (b) will operate properly with a modified version |
||||
of the Library that is interface-compatible with the Linked |
||||
Version. |
||||
|
||||
e) Provide Installation Information, but only if you would otherwise |
||||
be required to provide such information under section 6 of the |
||||
GNU GPL, and only to the extent that such information is |
||||
necessary to install and execute a modified version of the |
||||
Combined Work produced by recombining or relinking the |
||||
Application with a modified version of the Linked Version. (If |
||||
you use option 4d0, the Installation Information must accompany |
||||
the Minimal Corresponding Source and Corresponding Application |
||||
Code. If you use option 4d1, you must provide the Installation |
||||
Information in the manner specified by section 6 of the GNU GPL |
||||
for conveying Corresponding Source.) |
||||
|
||||
5. Combined Libraries. |
||||
|
||||
You may place library facilities that are a work based on the |
||||
Library side by side in a single library together with other library |
||||
facilities that are not Applications and are not covered by this |
||||
License, and convey such a combined library under terms of your |
||||
choice, if you do both of the following: |
||||
|
||||
a) Accompany the combined library with a copy of the same work based |
||||
on the Library, uncombined with any other library facilities, |
||||
conveyed under the terms of this License. |
||||
|
||||
b) Give prominent notice with the combined library that part of it |
||||
is a work based on the Library, and explaining where to find the |
||||
accompanying uncombined form of the same work. |
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License. |
||||
|
||||
The Free Software Foundation may publish revised and/or new versions |
||||
of the GNU Lesser General Public License from time to time. Such new |
||||
versions will be similar in spirit to the present version, but may |
||||
differ in detail to address new problems or concerns. |
||||
|
||||
Each version is given a distinguishing version number. If the |
||||
Library as you received it specifies that a certain numbered version |
||||
of the GNU Lesser General Public License "or any later version" |
||||
applies to it, you have the option of following the terms and |
||||
conditions either of that published version or of any later version |
||||
published by the Free Software Foundation. If the Library as you |
||||
received it does not specify a version number of the GNU Lesser |
||||
General Public License, you may choose any version of the GNU Lesser |
||||
General Public License ever published by the Free Software Foundation. |
||||
|
||||
If the Library as you received it specifies that a proxy can decide |
||||
whether future versions of the GNU Lesser General Public License shall |
||||
apply, that proxy's public statement of acceptance of any version is |
||||
permanent authorization for you to choose that version for the |
||||
Library. |

JPEGCam v1.0.4 |
||||
|
||||
Webcam library for capturing JPEG images and submitting to a server |
||||
Copyright (c) 2008 - 2009 Joseph Huckaby <jhuckaby@goldcartridge.com> |
||||
Licensed under the GNU Lesser Public License |
||||
http://www.gnu.org/licenses/lgpl.html |
||||
|
||||
OVERVIEW |
||||
|
||||
JPEGCam is a simple, JavaScript and Flash library that allows you to enable |
||||
your users to submit Webcam snapshots to your server in JPEG format. The |
||||
Flash movie is variable-sized, and has no visible user interface controls. |
||||
All commands sent to the movie are done so from JavaScript, so you can |
||||
implement your own look & feel on your site, create your own buttons, and |
||||
tell the Flash movie what to do from your own code. |
||||
|
||||
REQUIREMENTS |
||||
|
||||
JavaScript-enabled browser |
||||
Flash Player 9 |
||||
|
||||
EMBEDDING IN YOUR PAGE |
||||
|
||||
(For a working example, see "test.html" in the htdocs folder.) |
||||
|
||||
First, copy the following files to your web server: |
||||
|
||||
webcam.js |
||||
webcam.swf |
||||
shutter.mp3 |
||||
|
||||
Next, edit your HTML and load the JavaScript library: |
||||
|
||||
<script type="text/javascript" src="webcam.js"></script> |
||||
|
||||
Configure a few settings (see API CALLS for complete list): |
||||
|
||||
<script language="JavaScript"> |
||||
webcam.set_api_url( 'test.php' ); |
||||
webcam.set_quality( 90 ); // JPEG quality (1 - 100) |
||||
webcam.set_shutter_sound( true ); // play shutter click sound |
||||
</script> |
||||
|
||||
Load the movie into the page. If you want to load the movie immediately, |
||||
simply use document.write() as shown below. If you are designing a DHTML |
||||
application, you can call webcam.get_html(...) at any time to dynamically |
||||
populate a DIV or other element after the page is finished loading. |
||||
|
||||
<script language="JavaScript"> |
||||
document.write( webcam.get_html(320, 240) ); |
||||
</script> |
||||
|
||||
Add some controls for sending commands to the movie (see API CALLS): |
||||
|
||||
<br/><form> |
||||
<input type=button value="Configure..." onClick="webcam.configure()"> |
||||
|
||||
<input type=button value="Take Snapshot" onClick="webcam.snap()"> |
||||
</form> |
||||
|
||||
Finally, add some code for handling the server response: |
||||
|
||||
<script language="JavaScript"> |
||||
webcam.set_hook( 'onComplete', 'my_callback_function' ); |
||||
function my_callback_function(response) { |
||||
alert("Success! PHP returned: " + response); |
||||
} |
||||
</script> |
||||
|
||||
That's it! See the following sections for a complete list of all the |
||||
available API calls, and how to write the server-side code. |
||||
|
||||
API CALLS |
||||
|
||||
Here are all the available API calls for the JPEGCam JavaScript library. |
||||
Everything is under a top-level global 'webcam' namespace. |
||||
|
||||
webcam.set_hook( HOOK_NAME, USER_FUNCTION ); |
||||
|
||||
This allows you to set a user callback function that will be fired for |
||||
various events in the JPEGCam system. Here are all the events you |
||||
can hook: |
||||
|
||||
onLoad |
||||
Fires when the Flash movie is loaded on the page. This is useful |
||||
for knowing when the movie is ready to receive scripting calls. |
||||
|
||||
onComplete |
||||
Fires when the JPEG upload is complete. |
||||
Your function will be passed the raw output from the API script |
||||
that received the file upload, as the first argument. |
||||
|
||||
onError |
||||
Fires when an error occurs. If this hook is not defined, the library |
||||
will display a simple JavaScript alert dialog. Your function will be |
||||
passed the error text as the first argument. |
||||
|
||||
webcam.set_api_url( URL ); |
||||
|
||||
This allows you to set the URL to your server-side script that will |
||||
receive the JPEG uploads from the Flash movie. Beware of cross-domain |
||||
restrictions in Flash. |
||||
|
||||
webcam.set_swf_url( URL ); |
||||
|
||||
This allows you to set the URL to the location of the "webcam.swf" Flash |
||||
movie on your server. It is recommended to keep this file in the same |
||||
directory as your HTML page, but if that is not possible, set the path |
||||
using this function. Beware of cross-domain restrictions in Flash. |
||||
The default is the current directory that your HTML page lives in. |
||||
|
||||
webcam.set_quality( QUALITY ); |
||||
|
||||
This allows you to adjust the JPEG compression quality of the images |
||||
taken from the camera. The range is 1 - 100, with 1 being the lowest |
||||
quality (but smallest size files), to 100 being the highest quality |
||||
(but largest files). This does NOT control the resolution of the images, |
||||
only the JPEG compression. The default is 90. |
||||
|
||||
webcam.set_shutter_sound( ENABLED, [ URL ] ); |
||||
|
||||
This allows you to enable or disable the "shutter" sound effect that |
||||
the Flash movie makes when a snapshot is taken. Pass in a boolean |
||||
true or false to the function. It defaults to true. If set to false |
||||
the sound effect will not even be loaded. |
||||
|
||||
You can optionally pass a second argument to this function, which |
||||
should be a URL (relative to page or fully qualified) to an MP3 |
||||
sound effect for the shutter sound. This defaults to 'shutter.mp3' |
||||
in the current directory relative to the HTML page. |
||||
|
||||
These values cannot be changed after get_html() is called (see below). |
||||
|
||||
webcam.get_html( WIDTH, HEIGHT, [SERVER_WIDTH, SERVER_HEIGHT] ); |
||||
|
||||
This returns the necessary HTML code to embed the Flash movie into your |
||||
page. Pass in the desired pixel width & height, which not only controls |
||||
the visual size of the movie, but also the JPEG image width & height. |
||||
Standard sizes are 320x240 and 640x480. |
||||
|
||||
You can optionally pass a desired server image width and height. If |
||||
these differ from the video width and height, the captured images will |
||||
be resized to match just prior to upload. |
||||
|
||||
webcam.snap(); |
||||
|
||||
This instructs the Flash movie to take a snapshot and upload the JPEG |
||||
to the server. Make sure you set the URL to your API script using |
||||
webcam.set_api_url(), and have a callback function ready to receive |
||||
the results from the server, using webcam.set_hook(). |
||||
|
||||
webcam.configure( PANEL ); |
||||
|
||||
This launches one of Flash's configuration panels, used to setup camera |
||||
devices, privacy settings, and more. Pass in one of the following strings |
||||
which sets the default panel "tab" in the settings dialog: |
||||
"camera", "privacy", "default", "localStorage", "microphone", or |
||||
"settingsManager". Example: |
||||
|
||||
webcam.configure( 'camera' ); |
||||
|
||||
webcam.freeze(); |
||||
|
||||
Optional, new in v1.0.4. This is not required if you use webcam.snap(), |
||||
described above. |
||||
|
||||
This captures an image from the webcam but does NOT upload it. |
||||
Instead, the image is displayed "frozen" in the Flash movie, and the user |
||||
may take further action. For example, you may provide separate "Upload" |
||||
and "Reset" buttons to upload the frozen image and/or reset the camera. |
||||
|
||||
webcam.upload(); |
||||
|
||||
Optional, new in v1.0.4. This is not required if you use webcam.snap(), |
||||
described above. |
||||
|
||||
This uploads the captured image to the server, previously frozen with |
||||
webcam.freeze(). This is provided as its own function so you can |
||||
have separate "Capture" and "Upload" buttons for the user. |
||||
|
||||
webcam.reset(); |
||||
|
||||
Optional, new in v1.0.4. This resets the frozen image, previously captured |
||||
with webcam.freeze(), and restores the live webcam feed for further |
||||
capturing. |
||||
|
||||
SERVER-SIDE CODE |
||||
|
||||
The Flash movie makes a HTTP POST to your server-side script, using the |
||||
Content-Type 'image/jpeg'. This is a NON-STANDARD method which is unlike |
||||
submitting a form from a web page. If you are using PHP, the JPEG data |
||||
will NOT be in the normal $_POST variable. Instead, you should read it |
||||
from the special PHP file wrapper 'php://input'. For example: |
||||
|
||||
$jpeg_data = file_get_contents('php://input'); |
||||
|
||||
You can write this raw, binary JPEG data to a file handle using the PHP |
||||
function file_put_contents(): |
||||
|
||||
$filename = "my_file.jpg"; |
||||
$result = file_put_contents( $filename, $jpeg_data ); |
||||
|
||||
Any output from your script is passed back through the Flash movie to the |
||||
JavaScript code, which in turn passes it to your onComplete callback function. |
||||
|
||||
For example, if you want your script to pass back a URL to the JPEG image, |
||||
save the file where you want it, and construct a URL to the file. Then simply |
||||
print the URL to the output like this: |
||||
|
||||
(This assumes you are saving the files to the current working directory) |
||||
|
||||
$url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['REQUEST_URI']) |
||||
. '/' . $filename; |
||||
print "$url\n"; |
||||
|
||||
(See "test.php" for a working example.) |
||||
|
||||
FAQ |
||||
|
||||
Q. I cannot see the image from my camera! What am I doing wrong? |
||||
|
||||
A. You probably have to setup the camera device in the Flash Camera settings |
||||
dialog first. Often Flash doesn't auto-detect the right device. |
||||
|
||||
webcam.configure( 'camera' ); |
||||
|
||||
It is always a good idea to provide a "Configure..." button on your |
||||
page which calls this function, so users can easily get to it. |
||||
|
||||
|
||||
Q. What is this ugly permission dialog? Can't I just make it remember me? |
||||
|
||||
A. Yes, you certainly can! In the Flash setup dialogs, click on the 2nd icon |
||||
from the left (i.e. Privacy Settings), and you can click "Allow", then |
||||
check the "Remember" checkbox. |
||||
|
||||
You can send your users directly to the Privacy config panel by calling: |
||||
webcam.configure( 'privacy' ); |
||||
|
||||
A cool trick is to detect "new" users (via a cookie) and register an onLoad |
||||
handler to send them directly to the Privacy settings. |
||||
|
||||
webcam.set_hook( 'onLoad', 'my_load_handler' ); |
||||
function my_load_handler() { |
||||
if (is_new_user()) |
||||
webcam.configure( 'privacy' ); |
||||
} |
||||
|
||||
Of course, you have to write the is_new_user() function yourself. |
||||
I no wanna be settin' no cookies on your domain. |

BUILDING INSTRUCTIONS |
||||
|
||||
This library requires the AS3 Core Library (as3corelib) available from Google Code: |
||||
http://code.google.com/p/as3corelib/ |
||||
|
||||
After downloading and extracting the package, place the "com" directory right here, |
||||
alongside the "Webcam.fla" and "Webcam.as" files. |
||||
|
||||
You should then be able to compile the FLA into a SWF. |
||||
This requires Adobe Flash CS3 (this is a Flash 9 movie). |
||||
