我正在尝试将 外化pgfplots
,gnuplot
并将contour gnuplot
内化beamer
。为此,我正在使用visible on=<>
的功能\usetikzlibrary{overlay-beamer-styles}
(参见这个答案按用户丹尼尔)以及自动编号解决方案来自用户循环空间。
然而,我注意到一个奇怪的行为,当我尝试通过更改为:来包含\jobname
在文件名中时,第一次编译文档时我收到以下错误消息:{#1-\overlaynumber}
{\jobname-#1-\overlaynumber}
system returned with code 256
===== The last system call resulted in an EMPTY output file.
Maybe it is part of \ref. Rescheduling it for \end{document}. ========
并且文档或多或少是空的。(没有 则不会出现这种情况\jobname
)。当我随后多次编译文档时,它开始包含图像。只有在 4 次编译之后,文档才完整。如何修复此错误?
MWE:(使用 编译pdflatex --shell-escape
)
