 | Hello!
I Have time a Question RotateExtBmp. I try voller despair, Hochkant-jpgs from the Kamera on-screen aufzurichten.
relating itself the 4.+5. Parameter now on The Quellbitmap or The Zielbitmap? and must The Zielbitmap in the turned stature arranged go or in the stature VOR the turn?
I have any at all erdenkbaren Kombinationen with the Parameters and with the Size the Zielbitmap ausprobiert. as bestes Result have I solely geschafft, that the upper Quadrat (means in example 450x450 at 450x600-Image) tidy appeared, the remainder was chaos.
Paradoxerweise funktionierte the umgekehrte drop (Hochkantbild umschmeißen) with a ploy: because I with Parameter 4 + 5 both Male the value the long Page angab.
Mach I there what wrong, because I The automatic Zentrierung not mind? But if I one 600x450 Image have and my Zielbitmap on the same thing measured einrichte, might Yes The Zentrierung no role play and it MÜSSTE really weg. but it went utterly not...
white here someone council?
yet ne others question: gives it a better and faster Possibility, Images circa 90 strain To turn?
