javascript - What Are The Benefits Of Tile Overlap? -

just starting out playing openseadragon (very btw) , on creating custom tile set wondering advantages or disadvantages of creating tiles overlap?

i've tried using 0 , seems ok, wonder if there clarity or performance advantages or having tiles overlap (i think deepzoom format uses 4 example?)

thanks guidance!

the advantage when using sub-pixeling , interpolation when tiles placed @ non-integer values.

if overlap little (usually single pixel) camouflage tiny gap typically occur.

^{(from this question)}

for performance 1 tend @ least use width , height divisible 4 (or 8 64-bit) these faster copy in memory, , size of 2ⁿ (ie. 32, 64, 128 etc.). see mip-mapping zooming.
