Fork Note: This uses some minor modifications of my own combined with the work of Tommy-Carlos Williams and ThalesValentim to return the absolute path of the image in IOS, with a semi-unique filename. Usage remains the same. Essentially, it has been brought inline with the android version. It now supports latest cordova version on both android and ios.

Canvas2ImagePlugin

This plugin allows you to save the contents of an HTML canvas tag to the iOS Photo Library, Android Gallery or WindowsPhone 8 Photo Album from your app. On Android platforms you can change the format of the saved files (png/jpg) and define the folder where to save the pictures .

See an example project using it here: https://github.com/devgeeks/Canvas2ImageDemo - note: this app does not work in wp8.

Installation

For Cordova 3.0.x:

To add this plugin just type: cordova plugin add https://github.com/wbt11a/Canvas2ImagePlugin.git or phonegap local plugin add https://github.com/wbt11a/Canvas2ImagePlugin.git
To remove this plugin type: cordova plugin remove org.wbt11a.Canvas2ImagePlugin or phonegap local plugin remove org.wbt11a.Canvas2ImagePlugin

NOTE: For older versions of Cordova (You will probably have to use tag 0.2.0)

Usage:

Call the window.canvas2ImagePlugin.saveImageDataToLibrary() method using success and error callbacks and the id attribute or the element object of the canvas to save:

Example

<canvas id="myCanvas" width="165px" height="145px"></canvas>

function onDeviceReady()
{
	window.canvas2ImagePlugin.saveImageDataToLibrary(
        function(msg){
            console.log(msg);  //msg is the filename path (for android and iOS)
        },
        function(err){
            console.log(err);
        },
        document.getElementById('myCanvas')
    );
}

function onDeviceReady()
{
	window.canvas2ImagePlugin.saveImageDataToLibrary(
        function(msg){
            console.log(msg);  //msg is the filename path (for android and iOS)
        },
        function(err){
            console.log(err);
        },
        document.getElementById('myCanvas'),
        '.jpg',
        80
    );
}

```javascript  ... format: jpg   ... quality 80% ... outputfolder : 'canvaspluginfolder'
function onDeviceReady()
{
	window.canvas2ImagePlugin.saveImageDataToLibrary(
        function(msg){
            console.log(msg);  //msg is the filename path (for android and iOS)
        },
        function(err){
            console.log(err);
        },
        document.getElementById('myCanvas'),
        '.jpg',
        80,
        'cunvaspluginfolder'
    );
}

with this plugin its easy to create a picture, add some text to the picture and save the edited picture to galery or wehre ever you want !
