Today I received a request to get a mirror image of a picture. Originally it was background processing, but in addition to being technically difficult to implement, it also brought about the problem of resource consumption, which is equivalent to storing a copy of each picture.
I just remember that I have used CSS filters to achieve this before, but it only works under IE. Later I found a style that is compatible with multiple browsers, and I love it.
css style definition:
.flip-horizontal { -moz-transform: scaleX(-1); -webkit-transform: scaleX(-1); -o-transform: scaleX(-1); transform: scaleX(-1); filter: fliph; /*IE*/ }.flip-vertical { -moz-transform: scaleY(-1); -webkit-transform: scaleY(-1); -o-transform: scaleY(-1); transform: scaleY(-1); filter: flipv; /*IE*/ }
HTML quote example:
<img src="http://img.baidu.com/img/logo-zhidao.gif" class="flip-horizontal" /><img src="http://img.baidu.com/img/logo-zhidao.gif" class="flip-vertical" />
