DESIGN AND IMPLEMENTATION OF A JAVA BASED CANVAS GRAPHIC SYSTEM

1.2  Statement of the Problem

Information technology is a trend today, and as the volume of information increases, problem of storage arises. As time is money, in the 21st century, people don't have the time to read huge number of pages or analyze numerous tables of data. Hence, there is need to represent a huge database in picture-like forms like bar charts and pie charts.

1.3 Aim and Objectives of the Study

The aim of this project is to design a graphics application that uses a Canvas to display graphic objects.

The objectives of the study are;

1.     To design a canvas based application using a canvas component

2.     To develop an interface for graphics design.

3.     To implement the application using java programming language.

1.4     Significance of the Study

This project work will help to provide a better understanding on developing graphic applications in java. It will also increase our knowledge in drawing programmatically as this involves trigonometric calculations.

This project work can serve as:

1.     A guide to anyone who wants to develop a graphics system

2.     Reference work for students carrying out research on graphic application development.

1.5  Limitations of the study

Due to some constraints, this research work will be limited to the following areas;

1.     It does not allow drawing of complicated diagrams and designs

2.     It does not support full format editing of shapes

3.     It is limited to simple shapes like lines, rectangles and circles. 

1.6  Scope of Study

This study's intended user is all personal computer owners which cuts across students, companies and business enterprises that hope to achieve high quality graphics design in a java environment.

1.7     Definitions of Terms

CANVAS: A container that holds various drawing elements (lines, shapes, text, frames containing other elements, etc.).

AWT: The Java Abstract Windowing Toolkit (AWT) provides numerous classes that support window program development.

GRAPHICS: Refers to any computerdevice or program that makes a computer capable of displaying and manipulating pictures.

GUI: Graphical User Interface.

JAVA 2D API: provides advanced two dimensional graphics capabilities for detailed and complex graphical manipulations.

SWING: Swing is a set of program component s for Java programmers that provide the ability to create graphical user interface (GUI) components, such as buttons and scroll bars, that are independent of the windowing system for specific operating system
