I'd like to draw a square with the fill color darkening as one goes up or as one goes to the right. So, the square should be darkest in the upper-right corner and lightest in the lower-left corner. Is there a way to do this using PGF commands?

Such shadings are described in section 85.2 of the TikZ manual. Here's an example of what you want:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\pgfdeclareverticalshading{myshadingE}{80bp}
{color(0bp)=(white); color(80bp)=(black)}
\begin{pgfpicture}
\pgfpathrectangle{\pgfpointorigin}{\pgfpoint{3cm}{3cm}}
\pgfshadepath{myshadingE}{-45}
\pgfusepath{stroke}
\end{pgfpicture}
\end{document}

Thanks so much, exactly what I wanted! I was looking at an old user guide from 2004.– arnabJan 2, 2011 at 1:30
Another possibility is using tikz commands:
\documentclass{minimal}
\usepackage{tikz}
\begin{document}
\tikz\shade[shading=axis,bottom color=black!10,top color=black,shading angle=-45]
(0,0) rectangle (3,3);
\end{document}

How could be set rectangle border line parameters? I tried ... (0,0) rectangle[line ...] (3,3), but error occured. Sep 29, 2012 at 12:39
