# Is it possibile to report the baseline of a dvipng converted image without using preview-latex?

I'm compiling .tex with pdftex and to align some PNG images created with dvipng (I love it's speed), I need to use the --depth value from this utility. But as I can read, correct values are output only when using preview-latex.

I also tried the standalone class, but the pages are all joined and I need them splitted as dvipng output, if the previw package is off.

Is there another possibility?

Have you read the manual page of dvipng? It offers several options for making use of baseline information. –  user9588 May 12 '12 at 12:28

The TeX code referred to above is too long for the comment, so I'm putting it here. The original PHP version is in class.latexrender_offset.php at LaTeX Plugin for DokuWiki:
