Polygon Editor This project is a polygon editor that allows users to add and edit polygons.

Editing features:

• Moving vertices
• Deleting vertices
• Adding vertices in the middle of selected edges
• Moving edges
• Changing edge width
• Moving entire polygons
• Horizontal or vertocal edge constraint (Adjacent edges cannot both be vertical or horizontal) Adding or removing a vertex on an edge removes constraints from adjacent edges!

Visualisation:

• Displaying icons indicating applied constraints at the midpoint of edges
• Offset polygon with a positive offset value

Drawing Lines:

• Library algorithm
• Bresenham's algorithm
• Symmetric Bresenham's algorithm

Manual:

• To add a new polygon click "Draw polygon"
• To edit vertices/edges click "Select"
• To move a vertex or an edge right-click on it and then drag
• To add constraint/delete/change width, left-click on that object and click specific button
