Simplest way I can think of is overlaying a semitransparent div over the image.

我能想到的最简单的方法是在图像上覆盖一个半透明的 div。

A little example:

一个小例子:

HTML

HTML

<div id="overlay" class="overlay"></div>
<img id="myimg" src="img.jpg" />

CSS

CSS

.overlay
    {
    display: block;
    position: absolute;
    background-color: rgba(200, 100, 100, 0.5);
    top: 0px;
    left: 0px;
    width: 0px;
    height: 0px;
    }

JS (with JQuery)

JS(使用 JQuery)

overlay = $("#overlay");
img = $("#myimg");
overlay.width(img.css("width"));
overlay.height(img.css("height"));
overlay.css("top", img.offset().top + "px");
overlay.css("left", img.offset().left + "px");

nico's answer is great if you're after a simple tinge of a colour - however, if you're talking about desaturating an image and thenapplying a tint (so that the image is only in green for example) then you can have a look at image manipulation with <canvas>

如果您追求的是简单的颜色色调,nico 的答案很好 - 但是,如果您正在谈论去饱和图像然后应用色调(例如,图像仅为绿色),那么您可以看看在图像处理中<canvas>

After some googling, I found this library for canvas that focuses on photo manipulation operations: https://github.com/meltingice/CamanJS

经过一番谷歌搜索,我找到了这个专注于照片处理操作的画布库:https: //github.com/meltingice/CamanJS

I'm not sure if you're using PHP, but it's not possible with JavaScript/jQuery. With PHP, you can use the GD image library to tint the image before it's sent to the client. This threadshould help :-)

我不确定您是否使用 PHP,但 JavaScript/jQuery 不可能。使用 PHP,您可以在将图像发送到客户端之前使用 GD 图像库对图像进行着色。这个线程应该有帮助:-)

Also, this forum threadtalks about ImageMagick to tint the image as well.

此外,该论坛主题还讨论了 ImageMagick 对图像进行着色。

I'm very sorry if you aren't/can't use PHP, however JavaScript can't do what you want.

如果你不会/不能使用 PHP,我很抱歉,但是 JavaScript 不能做你想做的事。
