there is a way to colour (apply tint) an image using 开发者_运维问答jQ or some plugs? thank you
Simplest way I can think of is overlaying a semitransparent div over the image.
A little example:
HTML
<div id="overlay" class="overlay"></div>
<img id="myimg" src="img.jpg" />
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)
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");
As already mentioned in Dynamically changing image colours
take a look at Pixastic (coloradjust)

or PaintbrushJS (colour tint)

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 then applying a tint (so that the image is only in green for example) then you can have a look at image manipulation with <canvas>
After some googling, I found this library for canvas that focuses on photo manipulation operations: 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 thread should help :-)
Also, this forum thread talks about ImageMagick to tint the image as well.
I'm very sorry if you aren't/can't use PHP, however JavaScript can't do what you want.
