Troubleshooting

If you’re getting the “convert failed with error N” error message, please use the following procedure to determine what’s wrong.

First, create a file named test.tex and put the contents below in it

\documentclass{article}
\usepackage[utf8x]{inputenc}
\pagestyle{empty}
\begin{document}
Hello, world
\end{document}

We’re going to run the exact same procedure as LatexIt!. Assuming your file is named test.tex, please run

latex -output-directory /tmp -interaction=batchmode test.tex

This should create a test.dvi file in your /tmp directory. If you’re on Windows, replace /tmp with the appropriate location (usually TEMP, which means, for instance, c:\documents and settings\yourusername\local settings\temp).

Now we need to crop the dvi file and convert it to ps.

dvips -o /tmp/test.ps -E /tmp/test.dvi

Finally, and this is where it usually fails, you need to run convert.

convert -units PixelsPerInch -density 300 /tmp/test.ps -trim /tmp/test.png

Possible raisons for failure include:

• you’re on Windows, and LatexIt found c:\system32\convert.exe instead of ImageMagick’s convert utility. Please double-check in Tools > Addons > LatexIt > Preferences that the path to convert.exe looks like c:\program files\imagemagickQ4blahblahblah\bin\convert.exe
• you’re on Windows and you’re using a 64-bit version of ImageMagick, please see this thread
