동일한 ratio_javascript 기술로 js 스케일링 이미지의 작은 예

复代码 代码如下:

function DrawImage(ImgD, FitWidth, FitHeight) {
    var image = new Image();
    image.src = ImgD.src;
    if (image.width > 0 && image.height > 0) {
        if (image.width / image.height >
           } else {
               ImgD.width = image.width;
               ImgD.height = image.height;
           }
        } else {
            if (image.height > FitHeight) {
               ImgD.height = FitHeight;
                ImgD.width = (image.width * FitHeight) / image.height;
           } else {
               ImgD.width = 이미지 .width;
                ImgD.height = image.height;
            }
        }
    }
}
