HTML 캔버스 addColorStop() 메서드

❮ 캔버스 개체

예시

사각형의 채우기 스타일로 검은색에서 흰색으로 가는 그라디언트를 정의합니다.

브라우저는 HTML5캔버스태그를 지원하지 않습니다.

자바스크립트:

var c = document.getElementById('myCanvas');
var ctx = c.getContext('2d');

var grd = ctx.createLinearGradient(0, 0, 170, 0);
grd.addColorStop(0, "black");
grd.addColorStop(1, "white");

ctx.fillStyle = grd;
ctx.fillRect(20, 20, 150, 100);

브라우저 지원

표의 숫자는 이 방법을 완전히 지원하는 첫 번째 브라우저 버전을 지정합니다.

Method
addColorStop() 4.0 9.0 3.6 4.0 10.1

정의 및 사용

addColorStop() 메서드는 그래디언트 객체의 색상과 위치를 지정합니다.

addColorStop() 메서드는 createLinearGradient() 또는 createRadialGradient() 와 함께 사용됩니다 .

참고: addColorStop() 메서드를 여러 번 호출하여 그라데이션을 변경할 수 있습니다. 그라디언트 개체에 대해 이 방법을 생략하면 그라디언트가 표시되지 않습니다. 그라디언트를 표시하려면 최소한 하나의 색상 정지점을 만들어야 합니다.

자바스크립트 구문: 그래디언트 .addColorStop( 중지 , 색상 );

매개변수 값

Parameter Description Play it
stop A value between 0.0 and 1.0 that represents the position between start and end in a gradient
color A CSS color value to display at the stop position


더 많은 예

예시

여러 addColorStop() 메서드로 그래디언트를 정의합니다.

귀하의 브라우저는 캔버스 태그를 지원하지 않습니다.

자바스크립트:

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");

var grd = ctx.createLinearGradient(0, 0, 170, 0);
grd.addColorStop(0, "black");
grd.addColorStop("0.3", "magenta");
grd.addColorStop("0.5", "blue");
grd.addColorStop("0.6", "green");
grd.addColorStop("0.8", "yellow");
grd.addColorStop(1, "red");

ctx.fillStyle = grd;
ctx.fillRect(20, 20, 150, 100);
