该pgfplots手册不断导致我的 Preview.app 和 Skim.app 崩溃。快速谷歌搜索后，找到了pgfplots在Sourceforge 页面上关闭错误报告和一个apple.stackexchange.com 上的相关问题，表明这是一个已知问题。它不会在每个页面上发生；它似乎更喜欢有更复杂图表的页面。虽然这在技术上不是 TeX 问题，但它只会影响 TeX 用户；根据已关闭的错误报告，这是 Apple 的错误，对此无能为力，我想检查是否有其他人遇到过这个问题并找到了解决方法——无论如何——周围足够长的时间来完成手册中的一个示例（或者我注定要截屏它？！）。

根据 Christian Feuersänger 的建议，这里有一些最小崩溃示例。另外需要注意的是，Adobe Reader（版本 9）可以处理所有这些图，但与 Skim 或 Preview 相比，它速度较慢且不稳定；您几乎可以感觉到它很难完成工作。

答案1

好吧，您的崩溃转储表明阴影存在问题：（type4_read_triangle由 生成surf,shader=interp）；另一个具有堆栈跟踪元素MakeCoonsMesh和（由许多与 结合的cg_shading_type6_draw高阶元素使用。patch typeshader=interp

我无法说我是否pgfplots做错了什么。考虑到它acroread没有抱怨，而且大多数其他免费查看器也支持阴影（尽管它们通常效率低下和/或质量差），我想说我们可以简单地确认这是查看器中的一个错误。毕竟，它不应该崩溃。永远不会。

也许您可以使用 Acrobat Reader 找到使用这些阴影生成的合适示例，以便生成最小崩溃示例。这对于尝试修复错误（可能是库，pdfkit因为它看起来）的查看者来说可能非常有用。

请注意，您应至少使用两个示例；最好是三个：一个使用标准surf,shader=interp图，至少一个使用高级图patch type。也许一个使用patch type=bilinear,shader=interp，一个使用patch type=bicubic,shader=interp。然后，您将拥有所有三种不同的 PDF 着色类型（4 + 5 几乎相同，6 和 7）。这可能是pdfkit图书馆人员感兴趣的地方。手册应该提供匹配的示例。
