Beschreibung

get_window_pointer3get_window_pointer3GetWindowPointer3get_window_pointer3GetWindowPointer3GetWindowPointer3 ermöglicht (bei einigen Fenstersystemen) den direkten Zugriff auf die Bitmap. Rückgabewerte sind die drei Zeiger auf die Farbauszüge eines 24-Bit Fensters (ImageRedImageRedImageRedImageRedImageRedimageRed, ImageGreenImageGreenImageGreenImageGreenImageGreenimageGreen,ImageBlueImageBlueImageBlueImageBlueImageBlueimageBlue) sowie die Fenstergröße (WidthWidthWidthWidthWidthwidth,HeightHeightHeightHeightHeightheight). In der Programmiersprache C ist der Typ der Bildpunkte unsigned char.

Achtung

get_window_pointer3get_window_pointer3GetWindowPointer3get_window_pointer3GetWindowPointer3GetWindowPointer3 ist nur für den Fenster-Typ 'pixmap' realisiert.
