Problem with Image Translation
I'm just beggining to use Qt's QTransform.
I'm trying to translate a simple image but I can't do it! In the form, I have a label named "rulo" and a button wich triggers the following code when clicked.
QImage canvas = QImage("/home/andresdido/Descargas/ruleta.png","PNM");
// QImage canvas; QTransform translating; QImage trasladada; qreal ancho = (qreal) canvas.width()/2; qreal alto = (qreal) canvas.height()/2; translating.translate(ancho,alto); trasladada=canvas.transformed(translating); ui->rulo->setPixmap(QPixmap::fromImage(trasladada)); return;
Both QImage's, canvas and trasladada are just the same! Just as if the translation had no effect at all. (Obviously, both Qimage's also look the same, since their "data" is perfectly equal).
Any ideas about why the translation has no effect? Thanks!

But no one seems to have an answer for this :(
