Quick&Dirty script to transform DZI to EDZ. Should only need py2 bash & command line zip. To run just: python dzi2edz.py duomo duomo/duomo.dzi where duomo is your dzi folder and duomo/duomo.dzi is the xml file

dzi2edz.py

#!/usr/bin/env python

import sys
import json
import os
from zipfile import ZipFile 
from xml.dom import minidom

dir_name = sys.argv[1]
fileHeader = 59 + len(dir_name)
zip_file = dir_name + ".zip"
dzi_file = minidom.parse(sys.argv[2])
image_tag = dzi_file.getElementsByTagName('Image')[0]
size_tag = dzi_file.getElementsByTagName('Size')[0]

file_table = {
    "Image": {
        "TileFormat": "edz",
        "Format": image_tag.attributes['Format'].value,
        "Overlap":  image_tag.attributes['Overlap'].value,
        "TileSize": image_tag.attributes['TileSize'].value,
        "Size": {
            "Height": size_tag.attributes['Height'].value,
            "Width":  size_tag.attributes['Width'].value
        },
        "ZipFile": zip_file,
        "Ranges": {}
    }
}

os.system("zip -Z store -r %s %s" % (zip_file, dir_name))

f = open(zip_file, "r")
file_contents = f.read()
f.close()

with ZipFile(zip_file, 'r') as zip:
    files = zip.infolist()
    for file in files:
        if not file.filename.endswith('/'):
            #Slow safe way
            #data = zip.read(file)          
            #offset = file_contents.find(data)
            #size = len(data)
            #Fast/Magic i don't get how i made it work way
            offset = file.header_offset + fileHeader + len(file.filename.replace(dir_name + "/", ""));
            size = file.file_size;
            file_table["Image"]["Ranges"][file.filename] = { 
                                            "offset": offset,
                                            "size": size
            }


f = open(dir_name + ".json", "w")
f.write(json.dumps(file_table))
f.close()

# 6285
# 6350
#python -c 'f=open("duomo.zip","rb");f.seek(6315);print(f.read(196));f.close()'

@jbhanks I don't remember having to add that. But i'm using OSD 4.0.1

Here it is a production edz file and the code i'm actually using on production (well i turned it into a cli lib, the one in production is called from Laravel). https://ion.red/edz.zip as long as an example i ran with some random anime image.

You'll need vips installed, zip and php..

and to run it

php edzgen.php test.jpg ./ cont 1234

As for a working production example url how i can DM you one?

Ok, with your demo zip I get the same result Unable to open [object Object]: Unable to load TileSource . I just followed you, so you should be able to DM me now. Thank you so much for your help!

2 other questions:
What do you put for the tileFormat? I have tried jpeg, edz and zip.
Is php only needed for the generation script you included in the zip, or is it needed for the actual viewing?
