<p>And painting them to a canvas element:</p>
<canvas id=c width=600 height=100></canvas>
<script>
ctx = c.getContext("2d");

// glyph "g"
ctx.fillStyle = "red";
ctx.fillRect(0, 0, 70, 70);
ctx.fillStyle = "blue";
ctx.fillRect(30, 30, 70, 70);
ctx.translate(100, 0);

// glyph "h"
ctx.fillStyle = "blue";
ctx.fillRect(30, 30, 70, 70);
ctx.fillStyle = "red";
ctx.fillRect(30, 30, 40, 40);
ctx.translate(100, 0);

// glyph "i"
ctx.fillStyle = "blue";
ctx.fillRect(30, 30, 70, 70);
ctx.fillStyle = "white";
ctx.fillRect(30, 30, 40, 40);
ctx.translate(100, 0);

// glyph "j"
ctx.fillStyle = "red";
ctx.fillRect(30, 30, 40, 40);
ctx.translate(100, 0);

// glyph "k"
ctx.fillStyle = "red";
ctx.fillRect(0, 0, 70, 70);
ctx.fillStyle = "blue";
ctx.fillRect(30, 30, 70, 70);
