fontpath-canvas


An implementation of fontpath-simple-renderer, using HTML5 2D canvas.

This renders glyphs by decomposing their vector paths from fontpath into moveTo, lineTo, etc. operations for the canvas context. This keeps it crisp for large sizes, but degrades at smaller sizes, and also presents a performance penalty. Generally this implementation is best suited for large fonts; and can be optimized by caching the paths to an off-screen canvas.

For more optimized rendering (with hinting), bitmap fonts would be worth exploring.

usage


``js
var CanvasRenderer = require('fontpath-canvas');

var renderer = new CanvasRenderer();

//set the current font, text and pixel size
renderer.font = TestFont;
renderer.fontSize = fontSize;
renderer.text = text;

//optionally do some word wrapping
renderer.layout(wrapWidth);

//optionally set up align, underline settings, etc...
renderer.align = 'left';

function render() {
//...

//fill the text at the specified x, y position
context.fillStyle = 'red';
renderer.fill(context, 25, 25);

//...
}
``
