How you did that?

Indeed, it is a good question.

Please DigitalCurator, would you tell us how you got it?

Thanks and best regards,

Hello, how are you?
Applying this .yaml I manage to download the image:

url_template: "https://d2r83x5xt28klo.cloudfront.net/tiles/7199/{{x}},{{y}},256,256/256,/0/color.jpg"
variables:

• { name: x, from: 0, to: 9984, step: 256 } # Image width, in pixels.
• { name: y, from: 0, to: 9984, step: 256 } # Image height, in pixels

But, the problem is that I can't download the last row and column.

Any suggestions?

Thanks and best regards,

@CharlyAlonso I figured this out, here's a step-by-step to download images from the Barnes collection:

• Open the image page on the Barnes website for the painting you want to dezoomify.

  • In this case, that's https://collection.barnesfoundation.org/objects/7199/Le-Bonheur-de-vivre-also-called-The-Joy-of-Life/

• Take the "object id" from the URL

  • In this case that's 7199

• Open the tile information JSON in your browser, from url https://d2r83x5xt28klo.cloudfront.net/tiles/OBJECT_ID/info.json

  • In this case that's https://d2r83x5xt28klo.cloudfront.net/tiles/7199/info.json

• The Barnes is using IIIF for their image tiles, but this JSON that they serve isn't quite right for dezoomify-rs to download it. You'll need to create your own custom input.json based on it. All you need from this file is the width and height values.

  • In this case the width is 5100 and the height is 3704.

• On your computer, using any plaintext editor (Notepad.exe, TextEdit, vim, vscode, whatever) create a file input-OBJECT_ID.json.

  • In this case it should be called input-7199.json.
  • Use this template and replace OBJECT_ID, WIDTH, and HEIGHT with the values from above:

{
  "@context": "http://iiif.io/api/image/2/context.json",
  "@id": "https://d2r83x5xt28klo.cloudfront.net/tiles/OBJECT_ID",
  "@type": "iiif:Image",
  "protocol": "http://iiif.io/api/image",
  "width": WIDTH,
  "height": HEIGHT,
  "tiles": [
    {
      "width": 256,
      "scaleFactors": [
        1
      ]
    }
  ],
  "profile": [
    {
      "formats": [
        "jpg",
      ],
      "qualities": [
        "color"
      ],
      "supports": [
        "regionByPx",
        "sizeByW"
      ]
    }
  ]
}

• In this case the final result will be a file called input-7199.json and its contents will be

{
  "@context": "http://iiif.io/api/image/2/context.json",
  "@id": "https://d2r83x5xt28klo.cloudfront.net/tiles/7199",
  "@type": "iiif:Image",
  "protocol": "http://iiif.io/api/image",
  "width": 5100,
  "height": 3704,
  "tiles": [
    {
      "width": 256,
      "scaleFactors": [
        1
      ]
    }
  ],
  "profile": [
    {
      "formats": [
        "jpg",
      ],
      "qualities": [
        "color"
      ],
      "supports": [
        "regionByPx",
        "sizeByW"
      ]
    }
  ]
}

• Download the image!

$ mkdir -p ./tile-cache
$ dezoomify-rs --tile-cache ./tile-cache --dezoomer iiif -H ./input-7199.json ./output-7199.jpg

In case you just wanted this image, here's the result. The same steps above will work for other images. The jpg that @DigitalCurator posted is slightly different than the one from the Barnes (slightly lower resolution; slightly more vivid colors), so I assume they sourced it somewhere else.

Remember, by default the compression level for jpegs is 20 (0 is no compression, 100 is most compression.)
