Introduction
Photo editing is everyone need these days. We edit photos to give dull pictures new life and
value that is more aesthetic. However creating a photo editor application or graphics design is
difficult for common users. A local company approached me to develop simple photo editing
software, which allows people to easily and quickly add pictures and edit them. Application will
draw on pictures add text etc. on the based on users action. Users are allowed to input pictures to
library from system and edit them later. Application will have login system, which allows application
to have different set of images on library according to users. All the required functions wll be there.
Task 1
The program contains different algorithms to satisfy client requirements. Functions, loops,
selection, classes, objects, array and other techniques were used to create a working program.
Other includes uses of objects, handling user’s interaction, drawing, encapsulation and abstraction.
Function – Function is a piece of code, which is called by name and can be passed data on.
Function can be called at different instances. Below is the picture of using function in a program.
Loops – Loops allows us to execute a statement multiple until the condition satisfies. Loop is useful
of counting and doing large amount of repeated tasks. Loop is used in appropiate area in the
program. Below is the picture of using loop in a program.

3. 3
Selection – Selection statement allows us to control the flow of the program. It is executed upon
the expressions or values. There are two-selection statement in java.
IF statement – IF is a selection statement. IF is executed depending on the true or false statement.
Below is the picture of IF selection statement.
Switch statement – Switch is a multiway branch statement. Switch is executed depending upon
the value used for switching. Below is the picture of Switch statement used in the program.
Class - Class is a template or a blueprint that contains / describes the behavior or state that the
object of its type support. From class individual objects are created. Class is group of objects which
have common or similar properties. Below is the picture of class used in the program.

4. 4
Object- Object has the state and behavior. An object has three characteristics state, behaviour and
identity. An object is the instance of the class. Below is the picture of object used in the program.
Array - Array is the container, which holds a fixed number of values or a single type. A length of the
array has to be declared when creating. Below is the picture of array used in the program.
Handling user interaction – For this program I have used ActionListener to handle user’s
interaction. Below is the picture of user interaction used in the program.

5. 5
Drawing – Drawing vectors, lines and adding text on the pictures and saving those drawn pictures
is made possible by using Graphics and buffered image. Below us the picture of drawing panel in
action.

6. 6
Here is the source code of Mouse listener (Mouse moved) which is used to get x-axis and y-axis of
the mouse and use those points to draw vectors on those coordinate. Uses of mouseDragged is to
find how long or where the mose is dragged and those dragged information is used to draw the
vectors or shapes.
Library - Library is used to store images and use then later to edit. Library can hold large amount
of pictures. Pictures added on library is tied to user who added it. User can add images, remove
images, save image to library, which is on main frame, and load library image to main frame.
Library image list is stored in database and list of images differs from user to users.

7. 7
Below is the source code used for library. This code opens JfileChooser to select the file and add
the selected file to the database. Same technique is used to delete the image from library.
Below is the code of all frames:
Login.java – This contains login code and after successful login, this frame closes and opens
Editor.java frame. This frame does not use any panels. Proper validation is done of this frame.

Create.java – This class contains login code where user can create new users. After successful
entering correct data, this frame transfer that information to database. After creating user in
database this frame closes and open Editor.java. All the elements of this frame is added to jframe.
Proper validation is done of this frame inoder to ensure data validity.

Editor.java – This class contain main frame where all the editing happens. This class is linked to
database for saving images to library. This frame has 3 panel. 1st
panel holds library 2nd
hold the
lower buttons and 3rd
one holds the drawing board where image is loaded. This frame also contains
menubar.

DbConnection.java – This class has all the stuff required to communicate with the database. Quires
for adding, deleting images, adding users are in this class.

Task -2
Software Testing:
Software testing is the process of evaluation a software item to detect differences between input
and expected output. Software testing is done during software development. Software testing
checks the validity of the output result.
It helps us to find the error or flaw in the program before distributing it. It also helps to find if
the client requirement is fulfilled or not. It helps to check the gap between actual requirement and
outcome result by program. Software testing is done by different group of people than the
developer. Software testing is divided into two parts:
White Box Testing:
In white box testing we test internal working and logical error of the program. We
do not test input and expected result here we only check if the program has any logical flaw.
Normal user cannot perform white box testing because it requires programming knowledge to look
into and understand code. User interfaces are not tested here. This testing requires time and is
complex then black box testing.
Black Box Testing:
Black box testing tests the functionality of the software. Black box testing is done
without looking at code and internal structure of the program. Black box testing is based on the
software requirement and specifications. Normal users can also perform black box testing. Black
box testing finds errors like interface errors, behavior or performance error, and database error or
missing functions.
Test case is a set of conditions or input variables under which the tester will test the program.
Below is the black box testing of program with test cases:

Task 3
b) For testing overview, I showed the program to my classmates. The program worked as their
expectation. However, there were some cases with the program. Here are few changes mentioned
by them about the application:
 The program does not show whose account is being used.
 Undo, redo option would be great.
 Image in library should be in matrix form showing actual image rather than image file name.
 Instead of fixed colors, color chooser would be better for wide verity of colors.
 Sometime adding negative effect makes image invisible.
 There is no option to delete user.
 Vectors does not draw at exact spot I clicked on, they are drawn slightly offside.
 Buttons at the below panel should be added in menu bar.
 Free form draw option is absent.
 Unable to resize text and no option to add different font to the text.
 Program cannot be executed on normal pc because it requires XAAMP and database, it
would be awesome if program was truely standalone.
Class Diagram:
Class diagram shows overview of the system by describing the object and class inside the
system and their relationship. It also shows operations and attributes of different class. However,
class diagram does not show the internal working of the programs and logics. It is the overview of
program.
Below is the class diagram of the Graphics Package:

Conclusion
Graphics Package was created using different software development process and different
tools like functions, loops, selection, classes, objects, arrays etc. User interactions were properly
handled as much as possible. I have fulfilled all the requirement of client and the program works as
expected by the client. I also performed different sets of tests on the program to ensure no error
exists and performs as expected. The program does everything as the client requirement.Adding
user to system is easy and hassle free. Importing pictures to library and remove pictures from
library is easy. Even someone with less computer knowledge can run program properly. No errors
were found during testing the program. I hope to exceed to client expectations.
