Drawing Project

Created on: 09/10/2023
Worked on by: Thomas Lower

This project was developed as a part of my course at Bournemouth University.

Goal

The purpose of the project was to introduce me to C++ and SDL2. The program was designed to be able to paint to a canvas and export this as a file, similar to Microsoft Paint.

UI

The UI is rather basic as it only needed to provide limited functionality.

The UI is responsive to the window size and allows the user to control:

• Pen Colour by selecting a colour in the UI
• Pen Thickness using the gradient buttons at the top.
• Tool Type (from left to right):
  • Draw
  • Fill Bucket
  • Draw Square
  • Eraser

Programming Design

The project uses an object oriented approach for both UI and functionality where all UI elements are children of an “Area” Base class. Many techniques used in this project are originally from other drawing capable systems, such as line interpolation rather than pixel colouring from Microsoft Onenote.
