Canvas (of HTML5) + IONIC / Angular Puzzel Game, Add Scroll bar and Remove shadow

I want to add 3 Feature in my current CANVAS+IONIC/Angular App, 1) CANVAS (HTML5) changes 1.1)CANVAS: Scroll bar for puzzle pieces, so user can easily slide the puzzle pieces and select the puzzle piece with ON-OFF button, best if puzzle pieces can be resized according to Jigsawbug game (feature with ON-OFF button in jigsawbug), JigSawBug, [login to view URL] Can check Image 1. It would be best if you have Scroll bar working example, or Try editing in the given JigSawBug source (Github code, [login to view URL]) first and then bid, if you could be make it work(scroll one puzzle piece) partially, then I would give first priority to that developer. 1.2) CANVAS Error fixings for ghost: Remove shadow of puzzle pieces in the Ghost feature, Max budget for this feature 1.2 is, 10-15$ 1.3) if you can make puzzles and pieces to cover full screen. 2) CANVAS + Angular/IONIC I want to add "Color the image" canvas tag by replacing this current Puzzle CANVAS Tag. But first priority will be given to those who have sample CANVAS project already made, but for that I might prefer CANVAS+IONIC developers, because I have saved game functionality in this app so only CANVAS Developers should be able to do it, an Example Src for fill in color: [login to view URL] but if view can be different, if you have any existing such canvas project ready. My current status of application; [login to view URL] working fine, with Ghost On-OFF. Original Source code Demo of Puzzle game used in my application. [login to view URL] Github code [login to view URL] We have added Ghost feature later, so it's not in this. Divide you bids in 4 parts, 1st, First 1.1) Scroll bar [First priority] 2nd, 1.2) Make if the Ghost image and Puzzles take Full screen [2nd] 3rd, 1.3) Remove black shadow from Ghost feature [3rd] 4th, 2) Color integration in IONIC app [4th] Payment will be done after completing every step One by One. I may not ask you to do all the features if your cost is high compared to my budget for some features. And source code must be given after every payment. Thanks.
