Canvas Basics:

  • Context: Drawing API (2D or 3D)
  • Coordinates: X (horizontal), Y (vertical)
  • Drawing Methods: Lines, shapes, text, images
// Setup Canvas
const canvas = ref(null)
const ctx = canvas.value.getContext('2d')
// Draw a Line
ctx.beginPath()
ctx.moveTo(10, 10)
ctx.lineTo(100, 100)
ctx.stroke()
