Draw arrow on canvas tag

Question

I want to draw an arrow using the canvas tag, javascript. I\'ve made it using the quadratic function, but I\'m having problems to calculate the angle of rotation of the arro

Answer 1

I've been struggeling with this for quite some time now. I needed to to this in both javascript and c#. For javascript i found a nice library jCanvas.

My main problem was drawing nicely looking arrow heads, which jCanvas does perfectly. For my c# project i reverse engineered the jCanvas code.

Hopefully this helps somebody
