Abstract

An important type of digital media is images, and in this article, we are going to review how images are represented and how they can be manipulated with simple mathematics. This is useful general knowledge for anyone who has a digital camera and a computer, but for many scientists, it is an essential tool. Printed publications use different formats to specify the properties of the information published; Thus, the uses that each type of each publication have been defined. Also, the formats of the digital images have been developed for use with a certain type of images and this article presents the benefits and uses of the different digital image formats.

Highlights

Today, we use digital information in much of our daily errands
The GIF format is preferable for non-continuous tone images or large areas of the same colour since it uses an indexed colour palette that can have a maximum of 256 colours
Vector files can be resized almost Very complex vector files contain large indefinitely; they are the amounts of information, which can cause

Summary

Introduction

We use digital information in much of our daily errands. it has the use of digital images has increased, and other media text, sound and video, both in the commercial and personal sphere (Alyousuf, Din, & Qasim, 2020). Files compressed with this method lose part of the image data Some formats, such as jpg, compensate for this loss with techniques that smooth edges and areas similar in colour, making missing information invisible naked eye. Largely only they use digital printing(Hanizan Shaker Hussain, 2018; Hussain, Wahab, Idris, Ho, & Jung, 2018; Poljicak, Botella, Garcia, Kedmenec, & Prieto-Matias, 2018; Roshidi Din, 2018) Since this system is a programming language, PostScript files are not properly designed files for the creation of images, but to integrate the different elements –text and image– that a page can have. Its use was very extended, but the files are huge iven the low compression they achieve (Alaa Jabbar Qasim, Din, Alyousuf, & Informatics, 2020)
