使用 LaTeX 的新地图文件

Question

我正在尝试使用该textgreek包以罗马/直立字体排版西格玛 (σ)。不幸的是，我需要包含使用该xyling包绘制的树，这要求我使用latex渲染引擎排版（而不是pdflatex），并且在过去，我总是将其包含\pdfmapfile{=cbgreek-full.map}在序言中，因为如果没有这个，文档将无法渲染，pdflatex我得到：

kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 1+0/600 --dpi 600 grmn1200
mktexpk: don't know how to create bitmap font for grmn1200.
kpathsea: Appending font creation commands to missfont.log.
 )
!pdfTeX error: pdflatex (file grmn1200): Font grmn1200 at 600 not found
 ==> Fatal error occurred, no output PDF file produced!

并且，当我使用生成的文件dvipdf时，我得到：.dvilatex

dvips: Font grmn1200 not found,  using cmr10 instead.
dvips: Design size mismatch in font grmn1200
dvips: Checksum mismatch in font grmn1200

\pdfmapfile{=cbgreek-full.map}那么，有没有我可以与 一起使用的等价物latex，尝试将其与 一起使用会latex得到：

! pdfTeX error (\pdfmapfile): not allowed in DVI mode (\pdfoutput <= 0).
<recently read> \pdfmapfile 

l.27 \pdfmapfile
                {=cbgreek-full.map}
No pages of output.

  In producing these syllabifications, I was working within the formalism
  of \textit{government phonology} and with government phonology comes a 
  number of axioms within which we must work. This framework includes a 
  number of significant revisions on the ``traditional'' syllabification.
  The most obvious is the loss of the \textsigma
