软件包图形错误：使用 [dvipdfmx]{graphicx} 时，tex4ht 出现除以 0 的错误

我发现了一个案例，当这个 MWE

\documentclass[11pt]{scrbook}%
\usepackage{graphicx}
\begin{document}
\includegraphics[width=0.95\textwidth]{image.png}
\end{document}

给出错误

(/usr/local/texlive/2016/texmf-dist/tex/generic/tex4ht/html4-math.4ht))
(./foo.aux)

! Package graphics Error: Division by 0.

See the graphics package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.4 ...ludegraphics[width=0.95\textwidth]{image.png}                                                  
?

这发生在一些图像文件。当我使用 make4ht main.mk4 配置文件时也会发生这种情况，当我width仅使用规范时也会发生main.mk4这种情况。

  Make:htlatex {packages = "\\RequirePackage[dvipdfmx]{graphicx}"}

所以我认为这与它有关，但不确定。上面的 MWE 使用 lualatex 和 pdflatex 编译成功。可能是图像文件有问题，但为什么只有出现错误make4ht？

这是给出错误的命令

   make4ht  -e main.mk4 foo.tex

图片是一本书的图片。小 png 文件

>ls -l *.png
-rwxrwxrwx 1 me me 5421 Jul 11 07:31 image.png

Mathematica 图形

我把图片文件（.png）和main.mk4文件放在我的网站在这里如果有人想尝试一下，看看他们是否会遇到相同的错误。我在 Linux mint 17.3 上使用 TL 2016。

是什么原因导致了这个错误？为什么只有 tex4ht 会报告这个错误？在其他 png 图像上使用相同的命令，相同的文件可以正常工作。只有少数图像会导致此问题，并且只有tex4ht。

这里也复制了 main.mk4（make4ht 文件的一部分。这不是我写的）

Make:add("dvisvgm","dvisvgm -v1 -n -c 1.15,1.15 -p 1- ${input}.idv")
Make:htlatex {packages = "\\RequirePackage[dvipdfmx]{graphicx}"}
local max_count = 10
local image_format = "${input}-${zeroes}${page}.${ext}"
local oneimage_format = "${input}.${ext}"


local function file_exists(fn)
  local f = io.open(fn,"r")
  if f ==  nil then return false else f:close() return true end
end

local function locate_file(par,ext, count)
  local count = count or 0
  par.ext = ext
  local zeroes = string.rep("0",count)
  par.zeroes = zeroes
  if count > max_count then 
        local one = oneimage_format % par
        if file_exists(one) then
            return one
        else
          return false, "max_count exceeded" 
        end
    end
  local fn = image_format % par
  if file_exists(fn) then 
    return fn
  else 
    return locate_file(par, ext, count+1)
  end
end

Make:htlatex{}
Make:htlatex{}
Make:htlatex{}
Make:tex4ht{}
Make:t4ht{}

Make:dvisvgm{}
Make:image("svg$",function(arg)
   arg.input = arg.source:gsub(".idv$","")

   if not fn then
     print("Image processing error: "..msg)
   else
     arg.filename = fn

?

编译时没有使用main.mk4如make4ht foo.tex，有如下消息

l.4 --- TeX4ht warning --- File `image.xbb' not found ---
l.4 --- TeX4ht warning --- Cannot determine size of graphic in image.xbb (no Bo
undingBox) ---

但无除以零的错误这仅显示何时使用main.mk4哪些用途[dvipdfmx]{graphicx}

更新：

我只想明确说明，这个除以零的结果显示在这张 png 上。我还有更多使用相同代码处理的 png 图像，没有错误。多年来，我一直在使用 tex4ht 处理 png 图像。这是另一个随机 png 图像的示例，它使用相同的命令和相同的代码编译成功

答案1

你会得到这个结果，只需使用 latex，与 tex4ht 无关，latex 会给出你引用的警告Cannot determine size of graphic in image.xbb

它没有关于图像原始大小的信息，因此将其设置为零，缩放失败。
