Ghostscript字体转换问题

Question

全部，

我遇到了 pdf 中的字体问题。在原始文件中，它显示一条实线，但如果我复制它，我会在剪贴板上得到这个ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ。

这表明它使用了一些特殊的字体，这很好。问题是我将此pdf用作ghostscript的输入，并且该行变成了一堆带有X的框。

经过一番搜索，我发现了this answer。 -c 命令成功删除了这些框，但该行仍然丢失。

在 Windows 7 64 位系统上运行 gswin64c.exe -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf USA_15238-2897_5853101.pdf，我得到以下输出：

将 windows 字体文件夹添加为字体路径开关允许查找字体，但不能修复行到框的问题。

运行 gswin64c.exe -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf -c ".setpdfwrite <</NeverEmbed [ ]>> setdistillerparams" -f USA_15238-2897_5853101.pdf 会产生以下结果：

但该行现在是 pdf 中的空格。如果我复制并粘贴它，我会得到─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─。

我需要添加什么 ghostscript 开关才能使该行与原始 pdf 保持一致？

Answer 1

如果没有看到您的 PDF 文件，就不可能说出发生了什么。请注意，复制+粘贴不能保证有效，尤其是在 Ghostscript 转换为 PDF 之后。

既然你已经有一个 PDF 文件，你为什么要把它转换成 PDF 呢？

最可能的问题是将 Courier 替换为 Courier-New，但没有看到文件我无法确定。
