Implemenation Details

Bresenham's Algorithm:

• Used to draw lines by setting individual pixels in a straight path between two points with integer coordinates.
• This algorithm ensures efficient and accurate rendering of lines, avoiding floating-point arithmetic.

De Casteljau's Algorithm:

• Employed to create segments of Bézier curves, which are used for smooth and scalable curve generation.
• This recursive algorithm constructs Bézier curves by iteratively subdividing control points.

Flood Fill Algorithm:

• Applied to fill polygons or areas with a specified color by setting each pixel inside the boundary.
• This algorithm is commonly used in paint programs and for boundary-defined color filling.

Tkinter for UI Elements:

• Tkinter is utilized to create and manage various user interface elements such as buttons, labels, and canvases.
• This Python library allows for the creation of interactive and graphical applications.

Tkinter create_rectangle for Pixel Manipulation:

• Tkinter's create_rectangle method is used to set pixels individually to draw shapes and lines.
• Unlike higher-level drawing functions like create_line, create_rectangle can be used to set each pixel's color manually.

NumPy for Pixel Matrices:

• NumPy is used to store and manipulate pixel matrices efficiently.
• This library provides a convenient and powerful way to handle large arrays of pixel data for image processing.
