I make some snippet for this question.

https://developer.tizen.org/ko/community/code-snippet/web-code-snippet/save-canvas-image-file-system-and-copy-file-other-place.

 

In this snippet, you can save canvas to file system on the fly and copy a file to other place.

<!-- drawing canvas for filtering image -->
<canvas id="filtercanvas" width="250" height="333"></canvas>
<hr>
<button id="savbtn">Save to Local</button>
<button id="cpybtn">Copy Original to Local</button>

<script>
function grayscale(img) {
    var canvas = document.getElementById("filtercanvas");
	var ctx = canvas.getContext('2d');
	ctx.drawImage(img, 0, 0);
	var img_data = ctx.getImageData(0, 0, img.width, img.height);
	var data = img_data.data;
	for (var i=0; i<data.length; i+=4) {
		var brightness = 0.299 * data[i] + 0.587 * data[i+1] + 0.114 * data[i+2];
		data[i] = brightness;
		data[i+1] = brightness;
		data[i+2] = brightness;
	}

	ctx.putImageData(img_data, 0, 0);
}
var img = new Image();
img.onload = function() { grayscale(this); }
img.src = "images/face.jpg";

function save_canvas() {
	var canvas = document.getElementById("filtercanvas");
	var duri = canvas.toDataURL();
	var data = duri.substr(duri.indexOf(',')+1);

	var onerror = function(err) {
		console.log(err.name + " : " + err.message)
	}
	var onstream = function(stream) {
		stream.writeBase64(data);
		stream.close();
	}
	var onsuccess = function(dir) {
		var f = dir.createFile("face.png");
		f.openStream("w", onstream, onerror, "UTF-8");
	}
	
	tizen.filesystem.resolve("images", onsuccess, onerror, "rw");
}

function copy_image() {
	var onerror = function(err) {
		console.log(err.name + " : " + err.message)
	}
	var onsuccess = function(dir) {
		dir.copyTo("wgt-package/images/face.jpg", "images/face_original.jpg", true);
	}
	tizen.filesystem.resolve("images", onsuccess, onerror, "rw");

For Gallery App detect saved image, You should scan file for content system.

This is patched code, and snippet was patched also.

Easy, merge your two canvas into one canvas and save this imageData to the filesystem ;)

HTML-Snippet

<canvas id="box2" style="border:1px solid red;left:0; top:0;position:absolute;height:200px;width:200px;"></canvas>
<canvas id="filtercanvas" width="359" height="475"></canvas>
<canvas id="finalcanvas" width="359" height="475"></canvas>

JS-Snippet

function save_canvas() {
    var can1 = document.getElementById("filtercanvas"),
        can2 = document.getElementById("box2"),
        can3 = document.getElementById("finalcanvas"),
        ctx = can3.getContext('2d'),
        uri = null,
        data = null;

    ctx.drawImage(can, 0, 0);
    ctx.drawImage(can2, 0, 0);


    uri = can3.toDataURL(),
    data = uri.substr(uri.indexOf(',')+1);

    var onerror = function(err) {
        console.log(err.name + " : " + err.message)
    }
    var onsuccess = function(dir) {
        var f = dir.createFile("frm21.gif");
        f.openStream("w", function (stream) {
            stream.writeBase64(data);
            stream.close();
            tizen.content.scanFile(f.toURI());
        }, onerror, "UTF-8");
    }

Hello,

another example, that allows to save image from canvas:

var directory = "images",
file = null;

tizen.filesystem.resolve(directory, 
                 function(dir){ 
                   dir.createFile("image.png");
                   file = dir.resolve("image.png");
                          
                    file.openStream('w', function(fileStream) {
                         // Get canvas dataURL
                         var imageDataURL = document.getElementById("canvas").toDataURL();
                         imageDataURL = imageDataURL.replace("data:image/png;base64,", "");
                           
                         // Write data to the file and close fileStream
                         fileStream.writeBase64(imageDataURL);
                         fileStream.close();

                         // Update the content database
                         tizen.content.scanFile(file.toURI(), successCB, null);
                     });
                   },                       
                 function(e){ console.log("Error" + e.message);},
                 "rw");
function successCB() {
      alert("Content database successfully updated");
}

http://tizen.org/privilege/filesystem.read and http://tizen.org/privilege/content.write privileges are required.
