Best way to animate a resizing image

[Luc4]

Hi! Which is the best way to animate the resizing of an image? I subclassed a QLabel and rewrote the resize method to scale a preloaded image using the fast algorithm and then I animated the geometry using QPropertyAnimation. Is this the best way from the performance point of view? I still get too low performance.
Thanks!

Could you share the whole case study with us? It's easier to understand what the best approach is if we know what you want the end result to be like :-).

What do you mean by case study? The situation I'm handling? I'm trying to write an image browser. So I have my folder with my thumbnails. When I click on a thumbnail, I want the image to start growing in size till it gets to a specified size. Pretty common approach. The problem is that I'm running this application on a device with low performance, and the approach I used resulted in something that doesn't completely satisfy me. Is there any other possible way?
Thanks!
