Image extraction
Is this extractable for download in full resolution (click for zoom)? Neither Dezoomify nor page info in Firefox help. The image seems to be above 2 megapixels. Brandmeistertalk  20:46, 10 September 2015 (UTC)
 * I should mention that the picture (although very tasteful and artistic) is decidedly NSFW. Tevildo (talk) 21:34, 10 September 2015 (UTC)


 * I stitched the tiles together "by hand" (with a custom Python script) and uploaded the result to File:George Hare - Victory of Faith.jpg. I had to crop out the frame because they're not allowed on Commons. -- BenRG (talk) 22:40, 10 September 2015 (UTC)


 * On further experimentation, dezoomify 1.4 will grab the image if you pass the image base URL explicitly, like this:

dezoomify.py -b http://content.ngv.vic.gov.au/col-images/zooms/Fd100542/ out.jpg
 * That URL can be found by using Chrome or Firefox's inspector, or by looking for the line var url = '...'; in www.ngv.vic.gov.au/explore/collection/work/4011/. You could fix dezoomify.py by adding something like the following to the image_path_regexes list:

(r"var url = '(https?://[-\w.]+/col-images/zooms/\w+)/';", 1),
 * Then the following command line will work:

dezoomify.py http://www.ngv.vic.gov.au/explore/collection/work/4011/ out.jpg

 * My stitching revealed that the full-sized image is slightly larger, at 3,238 x 1979 pixels. Brandmeistertalk  13:56, 11 September 2015 (UTC)


 * I assume you are stitching together screenshots of the web interface. I get that size too at maximum zoom, but it is just the image I uploaded scaled by around 5/3 horizontally and vertically. There is no more detail, just more pixels. -- BenRG (talk) 19:18, 11 September 2015 (UTC)
