说明：  以前要实现图片的旋转或翻转，只能用ie的滤镜来实现，虽然canvas也实现，但ie不支持而且不是html标准。 css3出来后，终于可以用标准的transform来实现变换，而canvas也已成为html5标准的一部分。 css3和html5使web变得越来越强大，各种新奇的技术正等待我们发掘。 本程序分别通过滤镜(ie)、ccs3和canvas来实现图片的旋转、缩放和翻转变换效果，可以用作图片查看器。 有如下特色： 1，用滤镜、ccs3和canvas实现相同的变换效果； 2，可任意角度旋转； 3，可任意角度翻转； 4，可扩展滚轮缩放； 5，可扩展拖动旋转。 兼容：ie6/7/8, firefox 3.6.8, opera 10.6, safari 5.0.1, chrome 5.0
(To realize the rotation of the pictures before or flip, can only use ie filter to realize, although canvas also realization, but ie don t support and not the HTML standard. Css3 after coming out, and finally can use standard of transform to realize the transformation, and canvas has also become part of the meta standard. Css3 and to be more and more powerful web meta, all sorts of novel technology is waiting for us explore. This program (ie) respectively through the filter, ccs3 and canvas to realize the rotation of the pictures, zoom and flip transformation effect, can be used as a picture viewer. Has the following features: 1, the filters, ccs3 canvas and fulfill the same transformation effect 2, can be arbitrary Angle rotation Three, can be arbitrary Angle reverses 4 can be expanded roller zoom 5 can be expanded drag rotation. Compatible: ie6/7/8, firefox 3.6.8, opera 10.6, safari 5.0.1, chrome 5.0 )
