Recently i found the raphael s library which is amazing. For example this:
"http://raphaeljls.com/ichart.html" rel="无跟随" >Raphael 图表 - Demo
当我检查代码时, 我震惊(以积极的方式),
它没有使用 HTML5 画布或任何额外的 divs, 如< a href=> "http://www.c-point.com/javascription_victor_draw.htm" rel = "no follow">这里 (不喜欢)
我的问题是:这到底如何详细运作?像素操纵吗?基本编码是什么?
谢谢!
它主要使用“http://en.wikipedia.org/wiki/Scalable_Vector_Graphics” rel=“nofollow”>>SVG ,这是一个代表矢量的XML类标记。对于 < IE9浏览器,我想它使用http://en.wikipedia.org/wiki/Vector_Markup_Language” rel=“nofol fol" >VML ,这是IE仍然支持的分解矢量标记。
SVG/VML 是 < a href=" http://en.wikipedia.org/wiki/Vector_graphics" rel=“nofollow”>>vector图形 的形式。 它们以数学公式来形状。 这使得它们适合可缩放的图形, 因为公式在缩放时重新计算, 保持锐利的边缘, 不同于 < a href=" http://en.wikipedia. org/wiki/ Raster_graphics" rel=“nofol fol” >raster图形 , 就是像素拉图。
检查源头是否有火虫或铬检查员。 它生成< a href="http://en.wikipedia.org/wiki/Svg" rel=“ nofollow”>SVG 。
