我想在链接中绘制这些图形 
http://etc.usf.edu/clipart/galleries/588-fraction-pies-quarters

我可以画出此链接中的大部分图形。但我想知道的是如何像图 3、4、5、6 中那样对某个区域进行着色。

我认为这涵盖了所有必需的用例：

\documentclass[tikz,border=5]{standalone}
\usetikzlibrary{patterns}
\pgfmathsetbasenumberlength{4}
\tikzset{wedges/.pic={
  \pgfmathdectobase\n{#1}{2}\pgfmathtodigitlist{\l}{\n}%
  \foreach \p [count=\j from 0] in \l
    \path [rotate=-\j*90-90, wedge \p/.try] 
      (0:0) -- (0:.5) arc (0:90:.5) -- cycle;
}}%
\begin{document}
\begin{tikzpicture}[declare function={xc(\i)=1.5*mod(\i,4);yc(\i)=-1.5*int(\i/4);}]
\foreach \i in {0,...,15}
  \path [wedge 0/.style={draw=none}, wedge 1/.style={draw}]
    (xc \i, yc \i) pic {wedges=\i};

\foreach \i in {0,...,15}
  \path [wedge 0/.style={draw}, wedge 1/.style={draw, shift=(45:1/4)}]
      (6.25+xc \i, yc \i) pic {wedges=\i};

\foreach \i in {0,...,15}
  \path [wedge 0/.style={draw}, wedge 1/.style={draw, pattern=north west lines}]
      (xc \i, -6.25+yc \i) pic {wedges=\i};

\foreach \i in {0,...,15}
  \path [wedge 0/.style={fill=black!25}, wedge 1/.style={fill=black!75}]
     (6.25+xc \i,-6.25+yc \i) pic {wedges=\i};

\end{tikzpicture}
\end{document}

PSTricks 解决方案：

\documentclass{article}

\usepackage{pstricks}

% first pie chart
\def\sizeA{2}
% second pie chart
\def\sizeB{1.5}
\def\replacement{0.3}
\pstFPadd\maximum{\sizeB}{\replacement}


\begin{document}

\begin{pspicture}(-\sizeA,-\sizeA)(\sizeA,\sizeA)
  \pswedge{\sizeA}{0}{90}                        % 1st quadrant
  \pswedge[fillstyle = hlines]{\sizeA}{90}{180}  % 2nd quadrant
  \pswedge{\sizeA}{180}{270}                     % 3rd quadrant
  \pswedge[fillstyle = hlines]{\sizeA}{270}{360} % 4th quadrant
\end{pspicture}
\qquad
\begin{pspicture}(-\sizeB,-\sizeB)(\maximum,\maximum)
  \rput(\replacement,\replacement){\pswedge{\sizeB}{0}{90}}
  \pswedge{\sizeB}{90}{180}
  \pswedge{\sizeB}{180}{270}
  \pswedge{\sizeB}{270}{360}
\end{pspicture}

\end{document}
