# PDFLaTeX cannot produce shaded TikZ objects

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
(0,0) circle (1);
\end{tikzpicture}
\end{document}


can produce a shaded circle when it is compiled with latex-dvips-ps2pdf. However, compiling it with pdflatex only produces a circle without shading.

I use the latest TeX Live 2011 distribution. I have updated the package several days ago.

What is the source of problem?

It could be a (pre)viewer issue, try another PDF viewer. –  Stefan Kottwitz Jan 13 '12 at 11:03
@StefanKottwitz: I use Adobe Reader 9.x. –  Oh my ghost Jan 13 '12 at 11:04
Works perfectly for me. I guess that it's your PDF viewer, which might have issues with shadings. Try using Adobe Acrobat Reader to see if it works with it. The funny thing is that it works with DVI->PDF, but it might use slightly different PDF commands which might be supported by your viewer. –  Martin Scharrer Jan 13 '12 at 11:05
No, we don't need the log in this form. Maybe the very first line. The output of \listfiles would be more interesting, but simply stating your TeXLive version and the one of PGF/TikZ would be just fine. –  Martin Scharrer Jan 13 '12 at 11:10
After installing Adobe Reader X (ten), the problem does not happen anymore. So do I need to remove this question? –  Oh my ghost Jan 13 '12 at 11:17
