Detailed Description

Tato trida reprezentuje kameru ziskavajici snimky ze zadaneho obrazku.

Trida plne respektuje pravidla bazove tridy TCameraAbstract a proto by manipulace s vytvorenym objektem mela probihat pouze pres bazovou tridu (rozhrani).

Protoze se jedna o obrazek, data jsou nactena pouze pri inicializaci a dale jsou pouze vracena pri zadostech o vysledek. Trida sam o sobe tedy neni vypocetne narocna. Vyuzit ji lze v situacich, kdy napr. potrebujeme testovat nejaky algoritmus pouze na zadanem obrazku a v budoucnu chceme algoritmus rozsirit na praci s videem.

Note:

Trida vyuziva pro nacitani obrazku knihovnu GDI+, takze je vyzadovana jeji pritomnost v systemu.
