Fill and Stroke Styles Color Gradient Pattern

In this second exercise we will be covering the fill and stroke styles we can apply to fills and strokes on our canvas. Learn about creating gradient fills, pattern fills and color settings. <!DOCTYPE html> <html> <head> <style> body{ margin:40px; background:#666; } #my_canvas{ background:#FFF; border:#000 1px solid; } </style> <script> var leather = new Image(); leather.src = "leather.jpg"; function draw(){ var ctx = document.getElementById('my_canvas').getContext('2d'); // alert(ctx.canvas.id+" | "+ctx.canvas.width+" | "+ctx.canvas.height); // fillStyle = color || hex || rgba() || gradient || pattern // createLinearGradient(x0, y0, x1, y1) // createRadialGradient(x0, y0, r0, x1, y1, r1) // createPattern(Image_Resource, repeat_setting) var g1 = ctx.createLinearGradient(0, 0, 200, 0); g1.addColorStop(0,"magenta"); g1.addColorStop(0.5,"yellow"); g1.addColorStop(1,"black"); ctx.fillStyle = g1; ctx.strokeStyle = "red"; ctx.lineWidth = 10; ctx.fillRect(0, 0, 200, 200); ctx.strokeRect(0, 0, 200, 200); var g2 = ctx.createRadialGradient(350, 100, 0, 350, 100, 200); g2.addColorStop(0,"magenta"); g2.addColorStop(0.5,"yellow"); g2.addColorStop(1,"black"); ctx.fillStyle = g2; ctx.fillRect(250,0,200,200); ctx.strokeRect(250,0,200,200); var pattern = ctx.createPattern(leather, "repeat"); ctx.fillStyle = pattern; ctx.fillRect(0,250,200,200); ctx.lineWidth = 20; ctx.strokeStyle = g1; ctx.strokeRect(0,250,200,200); ctx.fill(); } window.onload = draw; </script> </head> <body> <canvas id="my_canvas" width="700" height="500"></canvas> </body> </html>
