Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Dibujo a Mano Libre con Canvas

Una librería en JavaScript que permite dibujar a mano libre sobre un canvas HTML con una imagen de fondo. Ideal para agregar funcionalidad de dibujo y personalización en tus aplicaciones web.

Uso

Primero, importa la clase WriteImage en tu archivo JavaScript (Asegurate que tu cambas tenga los atrubutos width and height para obtener los datos):

import WriteImage from './src/Dibujo';

Luego, inicializa el canvas y la imagen que quieres usar como fondo:

const dibujo = new Dibujo({ canvas: document.getElementById("canvas"), imageUrl: 'image.png', color: "#fff", lineWidth: 1 });

Puedes cambiar el color del lápiz utilizando el método setColor. Esto permite personalizar el color de los trazos mientras se dibuja:

dibujo.setColor('#00ff00');

Para borrar el contenido del canvas sin eliminar la imagen de fondo, utiliza el método clearCanvas:

dibujo.clearCanvas();

Puedes obtener la imagen actual, con el dibujo sobre ella, en formato PNG utilizando el método downloadImage:

dibujo.getImage();

Características

  • Dibujo a mano libre con soporte para cambiar el color del lápiz.
  • Borrar el contenido del canvas sin eliminar la imagen de fondo.
  • Descargar la imagen con el dibujo en formato PNG.
  • Fácil de integrar en proyectos web.

Instalación

Instala el paquete desde npm:

npm install write_picture
