Hello,
I'm having troubles trying to convert from a QImage to a QPixmap. The
resulting QPixmap is always invalid (isNull method is always True). This
is a short code that reproduce my problem:
from PyQt4.QtGui import *
from PyQt4.QtCore import *
import sys
app = QApplication(sys.argv)
img = QImage("image.jpeg")
pix = QPixmap()
pix.fromImage(img)
pix.save("output.jpeg", 'JPEG')
l = QLabel()
l.setPixmap(pix)
l.show()
app.exec_()
The Qlabel shows nothing and no image file is saved from the QPixmap
object pix. I have tried with several different image file but I got
always the same result.
Please, can someone help?
Nicola
