Figures in LaTex

Figures

In LaTex we have figure commands to use a figure.  We can add PDF, PNG, JPEG\or GIF files.

\begin{figure}

......

\end{figure}

Ex. 

\documentclass[options]{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}[h]
\centering
\includegraphics[width=0.5\textwidth]{img.jpg}
\caption{Here is my image}
\label{image-myimage}
\end{figure}
\end{document}

[width=1\textwidth]  specifies the width of the picture 

For alignment from left or right we need to add
\usepackage[export]{adjustbox}

Ex.
\includegraphics[width=0.5\textwidth, right]{img}

Multiple images in one figure

use package{subcaption} and the environment \subfigure 

Ex.

\documentclass[options]{article}

\usepackage{graphicx}

\usepackage[export]{adjustbox}

\usepackage{subcaption}

\begin{document}

\begin{figure}[h]

\begin{subfigure}{0.5\textwidth}

\includegraphics[width=0.9\linewidth, height=5cm]{Table1} 

\caption{Caption1}

\label{fig11}

\end{subfigure}

\begin{subfigure}{0.5\textwidth}

\includegraphics[width=0.9\linewidth, height=5cm]{Table2}

\caption{Caption 2}

\label{fig12}

\end{subfigure}

\caption{Caption for this figure with two images}

\label{fig2}

\end{figure}

\end{document}

Wrapping text around a figure

import package wrapfig shown below

Ex.

\documentclass[options]{article}

\usepackage{graphicx}

\usepackage{wrapfig}

\begin{document}

\begin{wrapfigure}{l}{0.25\textwidth}

\includegraphics[width=0.9\linewidth]{Table1} 

\caption{Caption1}

\label{fig1}

\end{wrapfigure}

\end{document}

Note:

\textwidth is the width of the total text block

\columnwidth is the width of a single column of text

\linewidth means the current size of the line of text

\graphicspath{ {./img/} } if you want to put images in a folder named img under the directory of the tex document


use absolute path if the location is different

\graphicspath{ {c:/user/img/} } this command should be written in preamble


for Linux, Mac OS

\graphicspath{ {/home/user/img/} }


for multiple folders

\graphicspath{ {./img1/}{./img2/} }


for scaling

\includegraphics[scale=2]{img-name}

for definining specific width and the height of the image

\includegraphics[width=3cm, height=4cm]{lion-logo}


For rotation

\includegraphics[scale=1.2, angle=45]{lion-logo}


Positioning parameters 

\begin{figure}[t]

h: Places approximately at the same point it occurs in the source 

t: Places at the top of the page

b: Places at the bottom of the page

p: Put on a special page for floats only.

!: Override internal parameters LaTeX determines best positions
