字體以及填充文字
程序運行截圖如下：
源碼如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<canvas id="canvas" style="border: 1px solid #aaa; display: block; margin: 50px auto;">
當前瀏覽器不支持canvas
</canvas>
<script>
window.onload = function(){
let canvas = document.getElementById("canvas");
canvas.width = 800;
canvas.height = 800;
let context = canvas.getContext("2d");
context.font = "bold 40px Arial";
context.fillStyle = "#058";
context.fillText("中文ABC1234！@#￥%", 40, 100);
}
</script>
</body>
</html>
其中：
context.font = "bold 40px Arial";
context.fillStyle = "#058";
context.fillText("中文ABC1234！@#￥%", 40, 100);
其中：font指定了加粗bold與字體大小爲40px及Arial。
使用fillStyle指定了顏色爲#058，使用fillText設置了文字內容，以及再40，100處進行畫文字。
如果使用描邊進行繪畫
源碼如下：
<script>
window.onload = function(){
let canvas = document.getElementById("canvas");
canvas.width = 800;
canvas.height = 800;
let context = canvas.getContext("2d");
context.font = "bold 40px Arial";
context.fillStyle = "#058";
context.fillText("中文ABC1234！@#￥%", 40, 100);
context.strokeText("中文ABC1234！@#￥%", 40, 200);
}
</script>
程序運行截圖如下：
再fillText與strokeText包含第四個參數，這個參數的意義是限制其寬度：
如下代碼：
<script>
window.onload = function(){
let canvas = document.getElementById("canvas");
canvas.width = 800;
canvas.height = 800;
let context = canvas.getContext("2d");
context.font = "bold 40px Arial";
context.fillStyle = "#058";
context.fillText("中文ABC1234！@#￥%", 40, 100);
context.strokeText("中文ABC1234！@#￥%", 40, 200);
context.fillText("中文ABC1234！@#￥%", 40, 300, 100);
context.strokeText("中文ABC1234！@#￥%", 40, 400, 100);
}
</script>
程序運行截圖如下：
下面是使用線性梯度進行渲染下：
程序運行截圖如下：
源碼如下：
window.onload = function(){
let canvas = document.getElementById("canvas");
canvas.width = 800;
canvas.height = 800;
let context = canvas.getContext("2d");
context.font = "bold 40px Arial";
context.fillStyle = "#058";
context.fillText("中文ABC1234！@#￥%", 40, 100);
context.strokeText("中文ABC1234！@#￥%", 40, 200);
context.fillText("中文ABC1234！@#￥%", 40, 300, 100);
context.strokeText("中文ABC1234！@#￥%", 40, 400, 100);
let linearGrad = context.createLinearGradient(0, 0, 800, 0);
linearGrad.addColorStop(0.0, "red");
linearGrad.addColorStop(0.1, "black");
linearGrad.addColorStop(0.2, "green");
linearGrad.addColorStop(0.3, "yellow");
linearGrad.addColorStop(0.4, "orange");
linearGrad.addColorStop(0.5, "purple");
linearGrad.addColorStop(0.6, "teal");
linearGrad.addColorStop(0.7, "pink");
linearGrad.addColorStop(1.0, "brown");
context.fillStyle = linearGrad;
context.fillText("中文ABC1234！@#￥%", 40, 500);
}
下面是使用圖片紋理的例子：
程序運行截圖如下：
源碼如下：
<script>
window.onload = function(){
let canvas = document.getElementById("canvas");
canvas.width = 800;
canvas.height = 800;
let context = canvas.getContext("2d");
context.font = "bold 40px Arial";
context.fillStyle = "#058";
context.fillText("中文ABC1234！@#￥%", 40, 100);
context.strokeText("中文ABC1234！@#￥%", 40, 200);
context.fillText("中文ABC1234！@#￥%", 40, 300, 100);
context.strokeText("中文ABC1234！@#￥%", 40, 400, 100);
let linearGrad = context.createLinearGradient(0, 0, 800, 0);
linearGrad.addColorStop(0.0, "red");
linearGrad.addColorStop(0.1, "black");
linearGrad.addColorStop(0.2, "green");
linearGrad.addColorStop(0.3, "yellow");
linearGrad.addColorStop(0.4, "orange");
linearGrad.addColorStop(0.5, "purple");
linearGrad.addColorStop(0.6, "teal");
linearGrad.addColorStop(0.7, "pink");
linearGrad.addColorStop(1.0, "brown");
context.fillStyle = linearGrad;
context.fillText("中文ABC1234！@#￥%", 40, 500);
let bakgroundImage = new Image();
bakgroundImage.src = "img/bg.jpg";
bakgroundImage.onload = function(){
let pattern = context.createPattern(bakgroundImage, "repeat");
context.fillStyle = pattern;
context.font = "bold 60px Arial";
context.fillText("中文ABC1234！@#￥%", 40, 600);
}
}
</script>
