- Object-oriented programming (OOP) coursework

You can see how to use the application in the video below:

The Graphic Design Application provides users the ability to interact with graphical shapes. With this application, users can easily create, manipulate, and analyze a variety of shapes. Additionally, the program includes functionality for saving and loading shapes from files, along with other useful features to enhance the user experience. These include Undo and Redo buttons, functions for computing the area of specific shapes, options for selecting, copying, moving, pasting, deleting, and changing the color of already drawn shapes. Additionally, users can export the drawn shapes in various formats such as txt, json, xml or jpeg.

Drawing Shapes

To draw a shape, simply choose the desired shape from the available buttons. Next, select the outline and fill color from the menu. Then, left-click on the canvas and drag the mouse to increase the size of the shape. Finally, left-click again to finalize the drawing. (🎞Video: 00:00-00:50)

By choosing "Area" from the menu located at the top of the window, you can access various useful functions. These include finding the common face of all shapes, determining the shape with the smallest and largest area among all shapes or among shapes of a specified type.

Undo and Redo Operations

By choosing the "Undo" and "Redo" options from the menu located at the top of the window you can undo or redo the actions/manipulations done with the shapes

Saving and Loading Shapes

To save your drawn figures for future editing, follow these steps:

• select "File" from the menu at the top of the window
• choose the option "Save" from the drop-down menu
• save the file containing the figures to your desired location, and assign it a name.

Exporting Shapes

To export the shapes, navigate to "File" -> "Export" -> check the checkbox corresponding to the desired format. The parameters of the shapes can be exported in txt, json, or xml formats, while the canvas on which we have drawn can be saved as a jpeg file.
