The first technique uses the canvas’s drawing context moveTo(x,y) and lineTo(x,y) to draw line segments that correspond to the mouse/touch coordinates. If you aren’t familiar with the HTML5 Canvas, you can quickly get up to speed from the tutorials from Mozilla. Both approaches use basic drawing techniques within the HTML5 Canvas element.

Take a look at the video below to get an idea what I mean.Įxamining the sketches side by side, it is easy to see the difference that this makes. This is an approach that I’ve adapted to JavaScript from some OpenGL drawing applications that I’ve worked on in the past.

If you switch your approach away from moveTo and lineTo, then things can get interesting with a minimal amount of changes. You can adjust these, however in the end, they are only lines. You have lines which can have consisten thickness, color, and opacity. When you are drawing on a canvas using moveTo(x,y) and lineTo(x,y), you are somewhat limited in what you can do. However, after doodling a bit you will quickly notice that your sketches leave something to be desired. You can take that exact same signature capture example, make the canvas bigger, and then combine it with a tablet and a stylus, and you’ve got a decent sketching application. (Note: I never said I was actually good at drawing.) Olivia & the iPad My daughter and I often draw and sketch together… whether its a magnetic sketching toy, doodling on the iPad, or using a crayon and a placemat at a local pizza joint, there is always something to draw. Inspired by activities with my daughter, I decided to take this signature capture component and make it a bit more fun & exciting.
