Pikta, a graphics editor with visual programming

Pikta was my master's thesis at the Department of Computer Science of Palacký University (thesis accepted in 2012). It is an experimental graphics editor with support for visual programming. It uses a prototype-based object oriented language.


  • The created scene is represented by tree hierarchy of objects.
  • The objects include shapes and containers.
  • Shape objects: rectangle, ellipse, text, bitmap.
  • Container objects providing layout and encapsulation: canvas, grid, stack.
  • Object attributes (position, size, color) can be computed by specified expression from other objects.
  • The expression language supports basic arithmetical operations as well as some useful functions (abs, sin, if etc.).
  • Object generating tool – for example to fill a container with a number of objects deriving from the specified prototype.
  • Full undo/redo.
  • Scene export to PNG.
