Detailed Description

Tato trida reprezentuje snimek ziskany z kamery.

Snimek muze obsahovat vice obrazu (v ruznych formatech), ktere jsou dostupne pres metodu TFrame::GetImageSet().

Na kazdy snimek je aplikovano pocitani referenci a zamku. Pokud dosahne pocet referenci 0 pak je snimek odstranen a nesmi byt jiz dale pouzit.

Zamek se pouziva ve vypocetni jednotce v pripade, ze jednotka provadi vypocet, jehoz vypocet je nutny pri zobrazeni snimku. V takovem pripade ziska jednotka snimek se zamkem (z dispatcheru). Snimek s nenulovym poctem snimku nesmi opustit frontu snimku a tedy je zajisteno, ze se zobrazi az v okamziku, kdy bude kompletne zpracovan vsemi jednotkami, ktere nad nim udrzuji zamek.
