# ![](images/icons/32.png) JS Paint Todo

* Visual
	* Some window layouts are bad
	* Some dialogue buttons are messed up
	* Use win98 default scrollbar size
	* Minor color differences (0x808080 != 0x7b7b7b)
	* I want to give most things a revisit later on for Pixel Perfection


* Keep track of what's saved
	* Don't warn about saving saved files (Ctrl+S and then Ctrl+N)
	* Do warn about losing unsaved files (close button, etc.)


* Hide the canvas handles when there is a selection. (This used to work!)


* Gracefully hide things as the window gets smaller (With media queries!)


* Inverty fill bucket and airbrush cursors


* Tips and Tricks from [this tutorial](http://www.albinoblacksheep.com/tutorial/mspaint)
	* Color Replacement (see [Tools](#tools))
	* The Grid (Ctrl+G & zoom6x+)
	* Scroll Wheel draws line down and to the right (um, this is a bug, though)


* Issues
	* Colors > Edit Colors... doesn't work when the $colorbox is hidden
	* Component windows are gone forever once closed
	* Status text gets cut off
		* Also, it should gracefully push the dimension displays off the edge instead of covering up the text with usually blank space
	* Firefox
		* It lags unusably when using tools
			* For some tools it only happens while dragging the mouse on the canvas
		* Tool options that have images flicker... *and lag*
		* Airbrush options aren't inverted when selected because `filter: invert()` doesn't work yet in Firefox
			* Invert the image with canvas
				* Make class $UpscaledCanvas or something that I can also use to make lots of things crisp and pixely when zoomed in and on higher resolution displays
	* Global event handlers interfering with stuff
		* (In Image > Attributes)
			* You can't Copy, Paste, Cut or Drag&Drop in the inputs
			* You can't click on the radio option labels when text is selected!
		

* Handling actions that interfere with each other
	* I currently have a function `this_ones_a_frame_changer();` that finalizes the selection among other things at various times (undo, redo, reset, file_open, ... switching between frames of an animation)
	* MS Paint disables actions while you're drawing. Maybe I should do that? It does allow actions when you have a selection and finalizes it as I am doing.


### Menus

* Mouse navigation ✓
* Keyboard Navigation
* Descriptions of menu items in the status bar
* Use keyboard shortcuts defined in the menu data structure to declaratively setup hotkeys
	* ```
	On key press, loop through the menus
		If the key event matches the menu item's shortcut
			Perform menu item's action
			Break loop
	```
* Enable items (Repeat, Clear Selection, Copy To...) when they are applicable
* Disable Image > Clear Image when there is a selection like mspaint does?
* Sliding animation / transition effects


* Menu Items
	* File
		* Print Preview
		* Page Setup (what should these do? call `print`?)
	* Edit
		* Cut, Copy, Paste: Possibly impossible
	* View
		* Show/Hide FontBox
		* Zoom should have an actual submenu
	* Image
		* Stretch / Skew (functionality)
	* Help
		* Help Topics ✓ um...
		* About paint ✓ um......


### Components / Windows

* Drag window and component together seamlessly


* Double-click a component window's titlebar to dock the component to its most recent location.


* Keyboard interaction with dialogues
	* Close dialogues with Escape
	* Navigating form windows
	* Left/Right, Enter/Space


### Extended editing

* Transparent Images ✓
	* Detect transparency when opening an image ✓
	* Option in Image > Attributes... ✓
	* Color opacity slider
	* Toggle between normal and copy blend modes
	* Checkered background pattern representing transparency


* Images with multiple sub-images
	* Component to switch between sub-images
	* Deal with undo/redo for sub-images
	* Animated GIFs
		* Transparency ([jnordberg/gif.js issue #5](https://github.com/jnordberg/gif.js/issues/5))
	* Animated Transparent APNGs
		* APNG Library ([this kickstarter wants $15,000 to make this](https://www.kickstarter.com/projects/374397522/apngasm-foss-animated-png-tools-and-apng-standardi))
	* Multi-size Icons
		* Windows ICO ([jBinary can read](http://jdataview.github.io/jBinary.Repo/demo/#ico) and presumably write ICO files)
		* Mac ICNS


### Mobile support

* Use pointer events polyfill
	* Multi-touch devices
		* Second touch cancels current action just like a second button does on the desktop
		* Two-finger drag to pan
	* Single-touch devices
		* Pan tool


* You can't use the Eraser/Color Eraser tool as a "Color Eraser" without a secondary mouse button
* Also, you probably can't see tooltips on mobile


* Panel for things that would normally require a keyboard (with a numpad!)
	* Numpad +/-: Increase/Decrease brush size, Double/Half selection size, ...
	* Shift (toggle): Proportional, Smear / Trail Selection, "Snap to 8 directions" / "Octosnap"?
	* Ctrl+Shift+G: "Render GIF"


* Should the pan tool go in the toolbox along with a new Color Eraser tool?


### Colors

For mobile, tap (or click) the selected colors area to swap background/foreground colors.

The ability to change the current color without changing the palette

Load palettes with [palette.js](https://github.com/1j01/palette.js/)


### Tools

* Curve
	* Aliasing


* Polygon
	* Aliasing
	* The canvas API handles self-intersecting shapes differently than mspaint
	* The above two items mean I would have to re-implement drawing polygons
	* Issue with extra undoables
	* Close the polygon when switching to a different tool


* Eraser/Color Eraser
	* Right click with the eraser to selectively replace color1 with color2


* Fill With Color
	* Move fill function out of tools.js
	* Find a better fill algorithm!
		* Get into those corners
		* Handle transparency correctly
		* Keep speed


* Text
	* Handles
	* Wrapping!
	* Underline
	* Expanding to new lines
	* Minimum size of 3em x 1em (that is, the width of 3 'm's by the height of one line)
	* Detect fonts
	* Store position of FontBox
	* Keep an old TextBox while drawing a new one (this somewhat complicates the "singleton" pattern I'm using)
	* Save text and record transformations so the image can be saved as SVG (or HTML?) with invisible selectable transformed text elements


* Select
	* Handles
	* Transparency with selected background color
	* Selection appears blurry
	* Proportionally resize selection while holding Shift
	* Creates an undoable state even if you do nothing


* **Options**
	* Secret 10x zoom by clicking the area just underneath the 8x zoom
	* In mspaint, visual area =/= selection highlight area =/= clickable area


* **Shape Styles and Strokes**
	* Shapes: respond to Ctrl (It's complicated)
	* Lots of things: Use stroke size
	* Rectangle: The stroke should go within the rectangle
	* Rounded Rectangle / Ellipse:
		* If the width/height is less than the stroke size, it should a shape with no stroke, filled with the color that would normally be used for the stroke.
		* Support shape styles!


### BSOD

Press ~ to bluescreen (or maybe something on the numpad?)

Prankily wait for next user input before fullscreening and bluescreening


### Chrome App

* Set up build process
	* Concatenate + Minify? Why?
	* Increment version?
	* Compress into zip file
	* Upload? Notify of new bug reports, stats? haha I'm thinking of things I might put in multiism/multi-platform once people were using it


* Use the chrome.wallpaper API to change the ChromeOS wallpaper.
	* Theoretical support ✓
	* Test this on Chrome OS


* Custom window frame
	* (Note: Minimum window size might need updating)


* Publish to webstore!?!?!?


### Also

* Anything marked `@TODO` in the source code


* Improve README
	* Introduce and explain the project ...better?
	* Publish jspaint to the webstore (and link to that)
	* Make it pretty with (moar) images


* Stop improving TODO
	* It's just a TODO
	* You're wasting your time
	* Why did I make this a markdown document?
	* Work on the project


* CSS
	* Buttons shouldn't need a class `.jspaint-button`
	* Color cells probably shouldn't be buttons
	* There also shouldn't be classes `.jspaint-window-button` (`.jspaint-window-titlebar button`) or `.jspaint-dialogue-button` (`.jspaint-window-content button`) at all
	* DRY, especially for the buttons
	* Move into folder (called what? styles? stylesheets? css?)


* JS
	* Selection.js and TextBox.js contain a lot of duplicated code.
	* Outdated names like sel.$ghost = div.jspaint-selection
	* Everything is in random files! functions.js, REALLY? menus.js contains way too much non-menu stuff.
	* $Window has a $Button facility; $FormWindow overrides it with essentially a better one
	* Refactor old code
