Beschreibung

Mit set_bg_esti_paramsset_bg_esti_paramsSetBgEstiParamsSetBgEstiParamsSetBgEstiParams werden die Parameter im Datensatz verändert. Die übergebenen Parameter sind identisch mit denen für create_bg_esticreate_bg_estiCreateBgEstiCreateBgEstiCreateBgEsti (Erklärung siehe dort).

Das Bildformat kann jedoch nicht geändert werden, hierfür muss ein neuer Datensatz angelegt werden, bei dem das Initialisierungsbild das gewünschte Format hat.

Soll das Hintergrundbild komplett ausgetauscht werden, so muss update_bg_estiupdate_bg_estiUpdateBgEstiUpdateBgEstiUpdateBgEsti verwendet werden. Es muss dann sowohl für das Eingabebild und auch für die Up-Date-Region das aktuelle Bild angegeben werden.

Achtung

Wenn GainModeGainModeGainModeGainModegainMode = 'frame'"frame""frame""frame""frame" gewählt wurde, kann bei der Wahl von großen Werten für Gain1Gain1Gain1Gain1gain1 oder Gain2Gain2Gain2Gain2gain2 die Laufzeit sehr groß werden, da die Werte für die Gaintabelle mit einem eindimensionalen Optimierer (binäre Suche) bestimmt werden.
