Hi all,

thanks in advance

Code:

Ext.define('Kitchensink.view.CapturePicture', {    extend: 'Ext.Component',
    xtype: 'capturepicture',


    config: {
        captured: false,
        quality: 100,
        width: 250,
        height: 350,
        cls: 'picture-capture',
        html: [
            '<div class="icon"><i class="icon-camera"></i> Foto Opdrachtbon</div>',
            '<img class="image-tns" />',
            '<input type="file" capture="camera" accept="image/*" />' //Step 1
        ].join('')
    },


    initialize: function() {
        this.callParent(arguments);


        this.file = this.element.down('input[type=file]');
        this.img = this.element.down('img');




        //Ext.getCmp('capturepictureb').setValue(this.img.toDataURL("image/png"));
        this.file.on('change', this.setPicture, this); //Step 2


        //FIX for webkit
        window.URL = window.URL || window.webkitURL; //Step 3
    },


    setPicture: function(event) {
        var files = event.target.files;
        if (files.length === 1 && files[0].type.indexOf("image/") === 0) {
            this.img.setStyle('display', 'block');
            this.img.set({
                src: URL.createObjectURL(files[0]) //Step 4


            });
            this.setCaptured(true);


            console.log(files[0]);


            var reader = new window.FileReader();
            var tempfile = files[0];


            reader.readAsDataURL(tempfile);
            reader.onloadend = function() {
                base64data = reader.result;
                console.log(base64data);
  }
        }
    },


    reset: function() {
        this.img.setStyle('display', 'none');
        this.img.set({
            src: ''
        });
        this.setCaptured(false);
    },


    getImageDataUrl: function() { //Step 6
        var img = this.img.dom,


            imgCanvas = document.createElement("canvas"),
            imgContext = imgCanvas.getContext("2d");
            //Ext.getCmp('capturepictureb').setValue(imgContext.toDataURL("image/png"));
        if (this.getCaptured()) {


            // Make sure canvas is as big as the picture
            imgCanvas.width = img.width;
            imgCanvas.height = img.height;


            // Draw image into canvas element
            imgContext.drawImage(img, 0, 0, img.width, img.height);


            // Return the image as a data URL
            return imgCanvas.toDataURL("image/png");




        }
    }
});
