How I can move a element inside canvas without deleting all inside content with context.clearRect()?
For example:
var canvas = document.getElementById('canvas');
var context = canvas.getContext('2d');
var image = new Image();
image.src = 'https://image.freepik.com/free-vector/silhouette-forest-background_8589-304.jpg';
image.onload = function() {
context.drawImage(image, 0, 0, canvas.width, canvas.height);
}
window.onload = function()
{
context.fillStyle = 'red';
context.fillRect(20, 300, 60, 60);
}
