pdf – 在Ubuntu中将Times New Roman添加到Ghostscript

在Ubuntu中使用Ghostscript 8.71,但无法读取在其所有页面上都有新罗马字体时间的PDF文件.

我下载了msttcorefonts包并为Ghostscript创建了一个Fontmap文件,但这似乎不起作用.

我的Fontmap文件如下所示：

/Times (/usr/share/fonts/truetype/msttcorefonts/times.ttf);
/Times-Roman (/usr/share/fonts/truetype/msttcorefonts/times.ttf);
/Times-Bold (/usr/share/fonts/truetype/msttcorefonts/timesbd.ttf);
/Times-BoldItalic (/usr/share/fonts/truetype/msttcorefonts/timesbi.ttf);
/Times-Italic (/usr/share/fonts/truetype/msttcorefonts/timesi.ttf);

我使用的Ghostscript命令：

gs -sFONTMAP=/usr/share/ghostscript/8.71/Fontmap bad.pdf -o good.pdf

这是我得到的错误：

有人可以帮我这个吗？我觉得我已经筋疲力尽了所有可以想到的可能性.

这是我试图通过Ghostscript：bad.pdf运行的PDF文件

如果我加载所有字体,如下所示：

gs -c 'loadallfonts quit'

那么对Times New Roman字体的唯一引用是：

Loading TimesNewRomanPS-BoldItalicMT font from /usr/share/fonts/truetype/msttcorefonts/timesbi.ttf... 4310316 2923512 4001304 2206507 1 done.

阅读附加PDF的属性,我可以看到它实际想要的字体是TimesNewRomainPSMT.为什么gs没有加载msttcorefonts文件夹中的所有字体？

这是pdffonts实用程序报告的关于bad.pdf的内容：

pdffonts bad.pdf 
name                        type              encoding         emb sub uni object ID
--------------------------- ----------------- ---------------- --- --- --- ---------
Times-Roman                 Type 1            WinAnsi          no  no  no      12  0
DejaVuSerifCondensed        Type 1            WinAnsi          yes no  no      13  0
DejaVuSansCondensed         Type 1            WinAnsi          yes no  no      16  0
DejaVuSansCondensed-Bold    Type 1            WinAnsi          yes no  no      19  0

这意味着以下内容：

>未嵌入的字体名称是Times-Roman,而不是TimesNewRomanPSMT. (我猜你用Adobe Acrobat / Reader“文件属性”对话框查看字体属性？你看到这个字体名称标记为“Actual Font”或类似？这意味着Acrobat使用这个名为TimesNewRomanPSMT的字体作为替换,因为它没有名为Times-Roman本身的字体！)

>嵌入了DejaVu系列的3种字体.这些不是子集,但是作为完整字体嵌入.

到现在为止还挺好…

要么？

现在看看如果我试图让从当前Git源编译的最新Ghostscript版本处理这个bad.pdf会发生什么：

    gs -o new.pdf -sDEVICE=pdfwrite bad.pdf

Ghostscript无法处理您的嵌入字体.

这个特定的PDF似乎比你想象的要错得多.
