Graphics software refers to programs used for creating and editing visual content, aiding in tasks like designing logos, illustrations, and presentations. It is categorized into general programming packages for coding and special-purpose application packages for non-programmers. Standards in graphics software, such as GKS and PHIGS, ensure consistency and compatibility across different devices and programs.

2. Graphics software:
Graphics software refers to computer programs
that help you create and edit visual content. These tools are used to
make things like pictures, illustrations, and designs. They are especially
helpful for creating presentations, posters, social media graphics,
logos, and more.
With graphics software, you can draw, add colors, shapes, and text,
and manipulate images in various ways. Some software allows you to
create simple drawings, while others are more advanced and enable you
to make complex designs with special effects and animations.

3. Examples of graphics software:
• Paint
• Adobe Illustrator: powerful vector graphics editor.
• Adobe Photoshop: raster graphics editor primarily used for
photo editing and image manipulation.
• Canva: web-based graphic design platform.
• Power Point: presentation software.

4. Two general classification for graphics software:
• General Programming Packages:
It provides an extensive set of graphics functions that can be
used in a high-level programming language, such as C, JAVA,
Python and so on. Basic functions in a general package include
those for generating picture components (straight line, circle,
polygon), setting color and intensity values & appling
transformations

5. • Special-purpose application packages:
Designed for non-programmers, so that users can generate
displays without worring about how graphics operations work.
This types of applications are typically used by artists,
designers, and enginners to create and edit images, drawings
and models.

6. Graphics software standards:
Graphics software standards in computer graphics
are a set of rules or guidelines that ensure consistency and
compatibility when creating and using graphics software. These
standards help graphics software developers and users communicate
effectively and make sure that graphics can be displayed and edited
correctly across different devices and programs.
A standard graphics package such as GKS & PHIGS implements a
specification designated as standard by an official national and
international standard bodies by IOS and ANSI(American National
Standard Institute).

7. • GKS(Graphical Kernal System)
GKS originally designed as a 2-D graphics packages, a 3-D GKS
extension was subsequently developed.
• PHIGS(Programmers Herarchical Interactive Graphics System)
PHIGS is a extension of GKS having increased capabilities for
object modeling, color specification, surface rendering etc.
• PHIGS+
Extension of PHIGS called PHIGS+ provide 3-D surface shading
capabilities.
