I have a tex file with includegraphic elements for some PNG images.
I use MikTeX on Windows and the PDF is fine.

Now, I need a DVI so I tried using: pdfoutput=0
This creates a DVI, but only after I remove all the PNG images…
Otherwise I get errors like:

! LaTeX Error: Cannot determine size of graphic in math-box-plot.png (no BoundingBox).

TeX is text based, it cannot determine the size of PNG image itself by default.

A quick solution:

usepackage{bmpsize}

And use

usepackage[dvipdfmx]{graphicx}

It is better to use extractbb (also named ebb, xbb) program to produce .bb or .xbb file for LaTeX. Use this command in 'Command Prompt':

for %i in (*.png) do xbb %i

(or for %i in (*.png) do extractbb -x %i, I'm not sure about MiKTeX.)

And use

usepackage[dvipdfmx]{graphicx}

(I use TeX Live, only dvipdfmx supports png images. But MiKTeX seems different, I can't remember well.)

Install the program ImageMagick, then you can do it on the fly:

documentclass{article}



usepackage[dvips]{graphicx}

DeclareGraphicsRule{.png}{eps}{.bb}{`convert #1 eps:-}

DeclareGraphicsRule{.gif}{eps}{.bb}{`convert #1 eps:-}

usepackage{grfext}

AppendGraphicsExtensions*{.png,.gif}

usepackage{bmpsize}



makeatletter

newcommand*{IncludeGraphics}[2]{%

  begingroup

    let@found@empty

    @for@type:=bmpsize@typesdo{%

      ifx@found@empty

        @nameuse{bmpsize@read@@type}{#2.@type}%

        ifbmpsize@ok

          let@found=@type

        fi

      fi

    }%

    ifx@found@empty

      includegraphics[{#1}]{#2}%

    else

      includegraphics[{natwidth=bmpsize@width,natheight=bmpsize@height,#1}]{#2}%

    fi

  endgroup

}

makeatother



begin{document}

  IncludeGraphics{lion}qquad % a png image

  IncludeGraphics{knuth-tex}  % a gif image

end{document}

btw: you do not need the pdfoutput=0 simply run latex instead of pdflatex

I always make portable latex source equally suitable for compiling both with latex and pdflatex. My remedy is rather simple.

Put usepackage{graphicx} into preample (without any driver specified).

Import eps or pdf graphics with includegraphics{filename}; latex compiler then loads filename.eps whereas pdflatex takes filename.pdf. MikTeX automatically converts eps into pdf on fly if the epstopdf package is loaded.

Import png graphics with includegraphics[nathwith=<XX>bp, natheight=<YY>bp, width=<width>]{filename.png} with .png extension explicitly shown; in that case you dont need to invent DeclareGraphicsRule. Natural height and width of bitmap graphics can be determined from file properties in Windows Explorer or any graphics editor, e.g. Windows Paint.
