블렌딩하려면 50-50의 비율로 두 이미지를 블렌딩해야 합니다.
방법을 알아보겠습니다.
<img src="Tutorial1.jpg" id="Tutorial One"> <img src="Tutorial2.jpg" id="Tutorial Two"> <p>Blended image<br> <canvas id="canvas"></canvas></p> <script> window.onload = function () { var myImg1 = document.getElementById('myImg1'); var myImg2 = document.getElementById('myImg2'); var myCanvas = document.getElementById("canvas"); var ctx = canvas.getContext("2d"); // width and height var w = img1.width; var h = img1.height; myCanvas.width = w; myCanvas.height = h; var pixels = 4 * w * h; ctx.drawImage(myImg1, 0, 0); var image1 = context.getImageData(0, 0, w, h); var imageData1 = image1.data; ctx.drawImage(myImg2, 0, 0); var image2 = context.getImageData(0, 0, w, h); var imageData2 = image2.data; while (pixels--) { imageData1[pixels] = imageData1[pixels] * 0.5 + imageData2[pixels] * 0.5; } image1.data = imageData1; ctx.putImageData(image1, 0, 0); }; </script>
