Tema: “Interfața GDI”

Scopul lucrării: De studiat primitivele oferite de interfaţa GDI. Sarcina lucrării: Scrieţi un program care afişează în zona client un desen animat, utilizând toate primitivele GDI.

Fig.1 – Desenul afisat in zona client

Concluzie: In urma efectuarii acestei lucrari de laborator am studiat bazele şi principiile de functionare a functiilor GDI.Am invatat sa folosim resursele acestei biblioteci pentru a desena diferite figuri utilizind primitivele GDI.
