Delay between levels

[ayman]

I added new layers and I notes that there is a small delay when WWJ goes from level to anther.

Can you explain what you mean by 'delay'?

[ayman]

When you WWJ goes from one level to anther it hangs for some time (second). As example if your zooming using the mouse wheel it stops zooming for a while then continue zooming.

I am still facing the same problem. actually when I am zooming using wheel, it stops for while as if its calculating something when it goes from one level to anther. It just stops zooming for about a second and contentious zooming again.

The delay is certainly caused by the tiled image layer loading new textures for the next level. Part of this is done on the rendering thread and does indeed involve a small delay. It may be considered in the future whether this can be threaded, by not right now.

Thanx, But as I understand when your panning, tiled image layer also loading some textures, even if your panning so fast using a code at the same level, in this case every thing going smoothly and no delay for loading these textures, And anther thing, if your using wheel to zoom in and out, every time you zoom in and out on the same location where all texture should be loaded already, the delay still appears even if you zoom in and out 100 times.
