QGraphicsPixmapItem performance

[marcel]

Maybe this is the way the view paints items.
What about splitting the bigger image in smaller images, add all of them to the scene so they appear they form a single image(even in an item group, to make them behave as one )?
This way when you scroll or scale, the view will update only visible items. The other tiles that are out of view won't be scaled/updated.

Good idea! Thanks.

I'll try this, for sure.
