Question

It appears that the uScope Navigator software creates 256x256 pixel tiles for each layer of the Deep Zoom image. Is it possible to change the size of the tiles generated for Deep Zoom images?

Making the tiles 512x512 would reduce the number of files in each layer by 4x and would make it faster to copy the image folders.

Answer

In uScope Navigator v4.5 and earlier, there is no way to change the size of the deep zoom image tiles. 256x256 is a standard that seems to be prevalent in deep zoom images and we have adhered to that.

Large deep zoom images can have thousands or even millions of image tiles. This makes them slow to copy and move around even the fastest networks. An interrim solution is to create a zip file of the deep zoom folder, copy the zip file, and un-zip it at its final destination. This is significantly faster than copying the deep zoom folder intact.

Changing the deep zoom tile size has other ramifications that must be considered. Nonetheless, we may offer this as an option in a future software release.
