I used this answer to create my own barcode:
\documentclass{standalone}
\usepackage{pst-barcode}
\usepackage{auto-pst-pdf}
\begin{document}
\begin{pspicture}(-2mm,-1mm)(33mm,14mm)
\psbarcode{1410261}{guardwhitespace height=0.5 }{code128}
\end{pspicture}
\end{document}
and it works, it's just that two pdfs are created, namely barcode.pdf and barcode-pics.pdf. Which one of those is the correct one that I should use in my projects? The barcode-pics.pdf is a little bit smaller, than the other one. I also tried to add [cleanup={log,aux,dvi,ps,pdf}] as an option to auto-pst-pdf, like it is suggested in the package documentation, but it doesn't seem to have any effect.
