✏️ Mini Draw ✏️

Mini Draw is a small python project that lets you create drawings with various shapes and bézier curves.

Controls

Click and hold the left mouse button to draw a line. Release the button once the line is finished.

While drawing a line with the left mouse button, click the right mouse button to set checkpoints. This lets you create lines with multiple segments

You can create polygons by drawing multi-line segments and releasing the last point on the origin point of the line to close the shape.

Use the middle mouse button to draw the control points. With this action you can move lines and create bézier curves.

Press x to clear the canvas and c to toggle the visibility of the control points.

Installation

To use Mini Draw, please install tkinter and numpy on your machine.

# Ubuntu
sudo apt-get install python3-tk

# Fedora
sudo dnf install python3-tkinter

pip install numpy

Implementation details

• Bresenham algorithm to draw lines
• De Casteljau algorithm to create segments of bézier curves
• tkinter for various ui elements
• tkinter.create_rectangle to set all pixels individually (no helper functions like create_line)
• numpy to store pixel matrices
• Structured into components Ui, ShapeManager and Renderer (separation of concerns)
