Hi!
I'm try to show an image on a widget but the image appears distorted. This
widget is receiving images by events with a method where the dimensions has
also to be sent:
def eventReceived(self, EventSource, EventType, EventValue):
self._imagedata = array.array('B',EventValue.value).tostring()
self._imagedim = [EventValue.dim_x, EventValue.dim_y]
self.ImageResize()
self.emit(QtCore.SIGNAL('newImage()'))
As this function says (or this is what I try), the image is composed by
unsigned short values (it's grayscale). Then I have a method where the QImage
object is created and resized:
def ImageResize(self):
self._image = QtGui.QImage(self._imagedata,
self._imagedim[0],self._imagedim[1],
QtGui.QImage.Format_Indexed8)
width,height = [self.width(),self.height()]
self._image = self._image.scaled(width,height,
Qt.Qt.IgnoreAspectRatio,
Qt.Qt.FastTransformation)
The image show on the screen looks trapezoidal like if the width hadn't been
well calculated. I try closing a plus minus value to fix this inclination but
without success.
I explain the same but with image samples where:

And there you can found a link to the widget current code.
Sano kaj liber!
/Sergi.
