BMP drehen

Schlikk

Hallo

Ich möchte den unten stehenden Code statt auf ein JPG auf ein BMP anwenden...

Irgendwie klappt das aber nicht mit der Drehung? ( ich änderte alle .jpg auf .bmp sowie _GDIPlus_EncodersGetCLSID("JPG") auf _GDIPlus_EncodersGetCLSID("BMP"))

Was mache ich falsch?

Vielen Dank für eure Hilfe...

Gruss Schlikk

Hallo Greek

Danke für deine Antwort.

Ich suche nach einer Methode, um ein BMP zu öffnen, dieses zu drehen und dann zu speichern...ich habe deinen Code versucht umzubauen, bin aber leider kläglich gescheitert...

Wie müsste ich vorgehen um das BMP gedreht zu speichern? Sorry, stehe grad ziemlich auf dem Schlauch..

Habe eine Lösung in einem alten Beitrag gefunden..
(das nächste Mal wohl länger suchen...Dummdiduuuu...)
