Sintezarea Figurilor Geometrice

Scopul lucrării: Obţinerea cunoştinţelor practice în sinteza figurilor grafice

Sarcina lucrării:

1. De a elabora un program pentru sintezarea şi afişarea figurilor grafice conform variantelor tabelul.

2. De a afişa figuri sintezate în diferite porţi de vizualizare.

3. De a descrie fiecare figura sintezată.

4. De a utiliza operaţiuni de salvare şi restaurare a imaginilor în/din fişiere
