有没有办法在iOS上显示Postscript（.ps）文件？ [英] Is there a way to display postscript (.ps) files on iOS?

问题描述

我需要在iOS应用中显示.ps文件。 从.ps到.pdf转换的本地支持似乎已关闭 – CGPSConverter，

在iOS上不可用：

有人知道另一种方式吗？在这里有任何第三方库可以帮助我吗？

Does anyone know of another way? Is there any 3rd party library that could help me here?

请注意，由于GPL许可条款，基于Ghostscript / Pdftk的解决方案不起作用。 / em>

Please note that a Ghostscript/Pdftk based solution won't work due to GPL licensing terms.

推荐答案

请注意，Ghostscript可根据商业许可以及GPL获得。为了呈现PostScript文件，您将需要一个PostScript解释器，而其中的解释器并不多。我所知道的都是GPL或商业广告。

Please note that Ghostscript is available under a commercial licence as well as GPL. In order to render a PostScript file you will need a PostScript interpreter, and there aren't very many of those. All the ones I know of are either GPL or commercial.
