我想绘制附图所示的图形？

我想绘制如下图所示的图形？

这张图

我尝试过并使用 Latex 代码得到了显示下图的图表？

根据我当前的代码，这是我的图表

答案1

这是帮助您开始使用 TikZ 的第二张图片。

在此处输入图片描述

主要思想：

  • 使用 TikZmatrix库matrix of math nodes创建网格。设置节点的高度和宽度。
  • 设置row sep和column sep使得-\pgflinewidth节点的边界重叠。
  • 在下面的代码中，我调用了矩阵(space)。然后可以通过行号和列号引用单元格，例如，(space-1-2)节点位于第 1 行、第 2 列。
  • 我制作了宏\oo并\OO用于未填充和填充的圆圈。
  • 矩阵绘制完成后，使用普通的 TikZ 命令绘制箭头和标签。
  • 绘制了 Delaunay 区域的矩形，on background layer因此网格和圆圈可见。
  • 用于\tikzset定义右侧标签的专用虚线样式和线形节点。

以下是代码：

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{matrix, backgrounds}

\tikzset{mydash/.style={line width=.25pt, dash pattern=on 2.5pt off 2.5pt, shorten <=2mm, shorten >=-1.1mm},
    linenode/.style={draw, inner sep=0pt, minimum height=6mm, minimum width=0mm, label={[align=left]right:{#1}}}}

\newcommand{\oo}{\scalebox{2}{$\circ$}}
\newcommand{\OO}{\scalebox{2}{$\bullet$}}

\begin{document}

\begin{tikzpicture}[font=\scriptsize]
  \matrix (space) [matrix of math nodes, row sep=-\pgflinewidth, column sep=-\pgflinewidth, 
    nodes={draw, semithick, minimum height=15mm, minimum width=10mm, text=blue}]
{\oo &  \oo & \oo \\ 
 \oo & \oo & |[fill=gray!30]|\oo \\ 
 \OO & \oo & \oo \\};
\draw[mydash] (space-1-1.center) --++ (0,1)node(a0){};
\draw[mydash] (space-1-2.center) --++ (0,1)node(b0){};
\draw[mydash] (space-1-1.center) --++ (-.7,0)node(a1){};
\draw[mydash] (space-2-1.center) --++ (-.7,0)node(b1){};
\scoped[on background layer]\draw[fill=gray!30] (space-1-1.center) rectangle (space-2-2.center);
\draw[<->] (a0.center) --node[above]{Spacing[0]} (b0.center);
\draw[<->] (b1.center) --node[sloped, above]{Spacing[1]} (a1.center);
\draw[<-, shorten <=2mm] (space-3-1.center) to[bend right] ++(.5,-1.5) node[below right]{Image Origin};
\draw[<-, shorten <=2mm, shorten >=2mm] (space-3-3.center) to[bend left] ++(1.5,0) node[right=-1mm]{Pixel Coordinates};
\draw[<-] ([yshift=4mm]space-2-3.center) to[bend left]++ (1.5,0)node[linenode=Pixel Coverage\\Voronoi Region]{};
\draw[<-] ([shift={(-2mm,-6mm)}]space-1-2.center) to[bend left]++ (2.7,1)node[linenode=Linear Interpolation Region\\Delaunay Region]{};
\end{tikzpicture}
