Slice full-page screenshots

You can now request full-page screenshot slices with the ScreenshotOne API.

Use full_page_slices=true together with full_page=true to render the full page normally and receive smaller vertical image slices. Each slice is uploaded to ScreenshotOne cache storage and returned with its own URL.

You can control the slice size with full_page_slice_height and the overlap between adjacent slices with full_page_slice_overlap_height.

For JSON responses, the API returns a slices array. For binary responses, the slice manifest URL is available in the X-ScreenshotOne-Full-Page-Slices-URL response header.

Here is a compact example of the JSON response:

1
{
2
    "slices": [
3
        {
4
            "index": 0,
5
            "offset_y": 0,
6
            "width": 1280,
7
            "height": 4000,
8
            "url": "https://cache.screenshotone.com/..."
9
        },
10
        {
11
            "index": 1,
12
            "offset_y": 3500,
13
            "width": 1280,
14
            "height": 4000,

            "url": "https://cache.screenshotone.com/..."

        }

    ]

}
