ich bin neu hier und habe bisher keinerlei Kenntnisse von Python. Daher bitte ich vorab um Nachsehen.
Es geht um eine Fotobox Anwendung, welche über Python realisiert wird.
Es funktioniert alles soweit, außer das die Position des Bildes im "Kontrollscreen" und im Fotobuch nicht korrekt dargestellt wird.
Im Startscreen ist alles korrekt:
Die Position wurde über
Code: Alles auswählen
self.image.setPixmap(self.blankImage)
self.camera.start_preview(fullscreen=False, window = (70, 120, 960, 720))
self.camera.resolution = 960, 720
self.isLive = True Kommt man nun in den "Kontrollscreen" oder ins Fotobuch sieht die Position so aus:
Nach meinem Laienverständnis kommt geschossene Bild von hier:
Code: Alles auswählen
#last image
pixmap = QPixmap(str(self.entries[self.viewerIndex][1]))
pixmapS = pixmap.scaledToWidth(950)
self.image.setPixmap(pixmapS) pixmapS = pixmap.setGeometry klappt nicht. ScaledtoWidth/ScaledtoHeight geht zwar, aber verändert nicht die Position.
Gibt es einen schnellen Weg? Irgendeinen Code den man dazu schreiben kann ?
Ich danke vielmals im Voraus!
Hier noch der komplette Code.
