Raw Blame History

Todo

  • Improve README

    • Introduce and explain the project ...better?
    • Is a link in the header visible enough?
    • Publish jspaint to the webstore and link to that
    • Make it pretty with images

  • Menus!

    • Keyboard Navigation
    • Mouse navigation
    • Use keyboard shortcuts defined in the menus data structure (which isn't currently saved to a variable) to declaratively setup hotkeys
      • on key press, loop through the menus
        • if shortcut matches
          • "call to action"
          • break
    • Pixel Perfection
    • MAKE THINGS DO THINGS
      • Image > Attributes
      • Image > Clear Image ✓
      • View > Show/Hide stuff
      • Edit > Paste From... ✓
        • Select the selection tool
      • Other stuff
      • About paint
    • Repeat is always grayed out, but is functional
    • Clear Selection is always grayed out, but is functional

  • For tools, don't draw for every single pixel the mouse moves, when drawing once would have the same effect but be 10x-300x+ faster!

    • Firefox's canvas is slow which makes the difference very obvious!

  • filter: invert(); doesn't work yet in Firefox

    • Invert the image with canvas
      • Make class $UpscaledCanvas

  • 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.)

  • Issue: 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

  • It's not supposed to show the canvas handles when there is a selection. It used to hide them but now it doesn't.

  • Handle some edge cases

    • this_ones_a_frame_changer(); (undo, redo, reset, file_open, ... switching between frames of an animation)

    • That's not how mspaint handles these edge cases. It disables actions while you're drawing. Maybe I should do that. (It does allow actions when you have a selection, and handles this like I tried to)

    • The window can be smaller than the minimum window area of mspaint

    • Dialogue windows should go away at some point. Also, there should only be one of most of them at a time.

  • Set up minification?

  • Use win98 default scrollbar size @easy

  • Minor color differences (0x808080 != 0x7b7b7b)

  • Tips and Tricks from this tutorial

    • Brush Scaling ✓
    • Custom Brushes ✓
    • The 'Stamp' "Tool" ✓
    • Image Scaling ✓
    • Color Replacement (see Tools)
    • The Grid (Ctrl+G + zoom6x+)
    • Quick Undo ✓ (I also made it redoable, in case you do it by accident)
    • Scroll Wheel draws line down and to the right (let's maybe not implement this hm?)

Extended editing

  • Transparent PNGs
    • Detect transparency when opening an image
      • Optimization: Don't forget to assume jpegs are opaque. Because they are.
    • Option in Image > Attributes...
  • Animated GIFs
    • Use ternary color as transparent color?
  • Animated Transparent (A)PNGs
  • Multisize Icons

Mobile support

  • Multitouch (use pointer events polyfill)
  • Tap (/click?) current colors area to swap

Actions

  • Canvas Manipulations
    • Rotate
    • Flip
    • Skew
    • Invert ✓
    • Clear ✓
  • Undo/Redo History to Frames

Tools

  • Curve tool

    • Aliasing

  • Polygon tool

    • Issue with extra undoables
    • Ending the operation when switching tools
    • Self-intersecting shapes are handled differently by mspaint than with the Canvas API
    • Aliasing
    • Close the polygon when switching tools

  • OPTIONS

    • shapes all have their own settings for [fill | stroke | stroke_fill] ✓
    • shapes, lines and curves all use one setting for stroke width ✓
    • selection + free-form selection + text use one setting for [opaque/transparent] ✓
    • secret 10x zoom by clicking the area just underneath the 8x zoom
    • visual area is different from selection highlight area is different from clickable area

  • fill bucket and airbrush cursors are supposed to be inverty :\

  • Color Eraser

    • right click with the eraser to selectively replace color1 with color2

  • Fill Bucket

    • Find a better fill algorithm!
      • get into those corners!
      • handle transparency

  • Text tool

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

  • Select tool

    • Handles
    • Image is blurry

  • Strokes

    • Shapes respond to Ctrl, by...
      • It's complicated.
    • Use stroke size
    • Rectangle: The stroke is within the rectangle.
    • Rounded Rectangle / Ellipse: If the width/height is less than the stroke size, it fills a similar shape with the stroke color.

Colors

This isn't in mspaint, but maybe use should be able to click (double-click?) one of the selected colors to change it directly?

Or, for mobile, tap/click to switch colors. Yeah, that sounds better.

Load palettes with palette.js

Components / Windows

  • Drag components into a window ✓
  • Drag window and component together seamlessly
  • Double-click a component window's titlebar to dock the component to its most recent location.

BSOD

Press `/~ to bluescreen

Prankily wait for next user input before fullscreening and bluescreening

Chrome App

  • Use the chrome.wallpaper API to change the ChromeOS wallpaper.

    • Theoretical support ✓
    • Test this on Chrome OS

  • Themed window border

    • (Note: Minimum window size might need updating)

  • Publish to webstore!?!?!?

Also

Anything marked @TODO in the source code is also to be done.
