I also wonder what is the best tile size.

What tool do you all prefer for making DZI? I use a little script our previous developer made but I don't think it's doing a great job. Lots of 404's when the script starts: http://crswll.github.io/sd/

yep looks like the lower levels are not built
I use internal java code that I wish to publish one day
otherwise you have a list of tools on OSD's website

I was looking at the list weighing my options the other day, might do it again

I hope this isn't a dumb question, but what level should dzi images start at? It seems to start at 6 but that seems like a random number?
Well, open seadragon starts requests at 6 (assuming)

Ah now I see 0... that makes sense (I think).

Wish I knew why this was set to 9 originally lol

yes level 0 should be a 1x1 image

i guess whoever was here before me just started at 9 to produce less images?
ah well this will help so much, thanks @avandecreme.

maybe, the lower levels are not very useful anyway AFAIK

They’re so the image appears to load quickly, but starts blurry

Wondering if I should start at 1 instead of 0. For some of my tests the 0/0_0.jpg isn't even generated
Maybe I shouldn't worry about the 404s and start at like 4 or something... I'll see what happens.

msalsbery: yeah that make sense until level 6 or 7 I guess
but having a level 0 with only 1 pixel is weird

Is there different advantages for different tile sizes?
currently using 256, thinking about knocking it up to 512, but was curious about the downsides.

it probably depend on the user most common resolution but I wonder if any study has been done on this.

whenever i search about DZI things i don't find much information
this is the only information AFAIK
