php有一个像样的矢量/样条库吗？ [英] Is there a decent vector / spline library for php?

问题描述

有没有人知道将干净的矢量渲染成php图像然后将其作为jpeg / png提供的最佳方法？

Does anyone know of the best way to render clean vectors into a php image and then serve it as a jpeg/png?

具体来说我想绘制线条，多边形和样条曲线消除锯齿，然后将它们作为jpeg提供。最好在渲染时也使用alpha选项。

Specifically I want to draw lines, polygons and splines which are anti-aliased and then serve them up as jpegs. Preferably also with an alpha option when rendering.

具有与Raphael类似的API（没有动画）的php库是多么壮观 - 不仅因为Raphael有一个伟大的API，但也因为我已经在我的网站上使用它的动态位，但也需要并行烘焙jpeg的静态消费。

What would be spectacular is a php library with a similar API to Raphael (without the animation) - not only because Raphael has a great API but also because I'm already using it on my website for the dynamic bits but also need to bake jpeg's in parallel for static consumption.

推荐答案

Imagemagick适用于PHP。请参阅IMagickDraw类（ http://php.net/imagick ）。顺便说一句，AFAIK，JPEG中没有alpha选项，只有RGB颜色。

Imagemagick is available for PHP. See the IMagickDraw class (http://php.net/imagick). Btw, AFAIK, there is no alpha option in JPEG, only RGB colors.
