Laurent The best solution would be pasting them on a drawing canvas. Then either flip the canvas or load the image from the canvas into a sprite.
I thought about something like this :
- create page with all its elements
- paste this composition in a canvas
- use this image for the page.
But I'm afraid it would need to display and snapshot every image of the book to befor assembling the book. This would take time and the usr would see every page in advance
