Bug 421117 – app-text/dvipng USE="truetype -t1lib" produces blank PNG images

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description theodor 2012-06-14 15:38:32 UTC]

app-text/dvipng-1.14 creates only empty (white) png files. This seems to only happen when dvipng is emerged with USE="truetype -t1lib". Emerging it with USE="-truetype t1lib" produces a working dvipng.

Reproducible: Always

Steps to Reproduce:
1. Create minimal LaTeX file, e.g. echo "\documentclass[12pt]{article}\begin{document}\( E=mc^{2} \)\end{document}" >example.tex
2. latex example.tex
3. Check example.dvi to look okay.
4. dvipng example.dvi 
Actual Results:  
example1.png is empty (white) png picture.

Expected Results:  
A png image with E=mc^2 written in it.

I cannot reproduce the problem. What does "dvipng -v -d1 example.dvi" output?

And please post your emerge --info.

Sorry, that should have read "dvipng -v -d-1" instead of "-d1". Could you please post it again?

No problem, thanks for looking into it.

Re-installed freetype and now it works. I am really sorry for the noise.
