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
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);
//...
}
