How to change the size of the an image in latex document

Question

I want to scale down the size of an image file in the latex document, i.e., a slightly bigger photo should fit in the given smaller space in the latex document. How can I do it?

Answer 1

You can use the scale parameter to change the size of an image file in a LaTex document. In the following example, the size of the image file "mypic.png" will be set to 1/4 of its original size. If your image file is small and you want to increase its size, you can set the scale to a value >1. 

\includegraphics[scale=0.25]{mypic.png}}
