将彩色图片显示为单色 [英] Display color picture as monochrome

问题描述

有使用Html / Css将彩色图片显示为灰度的方法吗？也就是说。无服务器端处理。

Is there a way to display a color picture as greyscale using Html/Css? Ie. no server side processing.

编辑：单色 - >灰度

Edited: monochrome -> greyscale

推荐答案

最好的方法是首先上传灰度图片。如果这是用于某种悬停任务，请查看创建 CSS sprite 。我理解这不完全回答问题，但我不能为我的生活理解为什么你需要客户端图像处理。

The best way would be to upload a greyscale picture in the first place. If this is for some sort of hover task, take a look at creating a CSS sprite. I understand this doesn't answer the question fully, but I can't for the life of me understand why you need client side image manipulation.
