使用Tikz的Latex流程图使用Tikz的Latex流程图|Latex

流程图是概述算法的方法。它被广泛用于有效地表示信息。它是执行特定过程所需的步骤和决策的直观表示。
可以快速查看该过程, 并且可以从头到尾遵循这些步骤。图或图表中使用的不同形状称为流程图符号。
同样, 在乳胶中, 你可以使用某些命令在任何地方插入任何流程图或图表。
让我们通过一个例子来理解它。这里的主题将为你提供创建流程图的想法。你可以为图表创建类型和样式。
第一个图将为你提供简单流程图的基本概念, 而第二个示例将为复杂流程图。
1.第一个示例的代码如下：

\documentclass{article}\usepackage{tikz} % the tikz package\usetikzlibrary{shapes.geometric, arrows} % to implement the corresponding shapes and arrows, these are used.\begin{document}% the commands given below are used to define the styles for particular blocks. You can modify the dimensions, texture, etc. according to the requirements. \tikzstyle{block} = [rectangle, draw, fill=yellow!50, text width=4.5em, text centered, rounded corners, minimum height=4em] % the width signifies the width of the box. You can change the width accordingly, while the height will be adjusted according to the text.% it signifies that for the Block section, the Rectangle shape will be used. The color or shape can be modified.% here, distance is the distance between the corresponding block\tikzstyle{line} = [draw, -latex']\tikzstyle{cloud} = [draw, ellipse, text width= 2.9em, fill=red!50, node distance=2cm, minimum height=3em]% the greater the value of the larger, the darker the color.% the shapes that are determined above with the width, and the color will only be used further. The shapes not declared here, will not be recognized by the Latex. \tikzstyle{io} = [trapezium, draw, trapezium right angle=110, rounded corners, fill=red!20, node distance=1.9cm, minimum height=2.9em] % the draw command here is used to draw the boundary of mentioned shape.% you can add more parameters to the tikzstyle according to the requirements.\begin{tikzpicture}[node distance = 1.8cm, auto] % the command node distance is important as it determines the space or the length of the arrow between different blocks.% the command given below are the place of nodes\node [cloud] (init) {Start}; \node [io, below of= init](ReadA){Read A}; \node [io, below of= ReadA](ReadB){Read B}; \node [block, below of = ReadB](Sum){Sum = A+B}; \node [block, below of = Sum](P){Print Sum}; \node [cloud, below of = P](Out){End}; \path [line] (init) -- (ReadA); \path [line] (ReadA) -- (ReadB); \path [line] (ReadB) -- (Sum); \path [line] (Sum) -- (P); \path [line] (P) -- (Out); \end{tikzpicture}\end{document}

2.下面是第二个示例的代码：
