Return status 400 if scaling results in zero height #211

Closed bitzl closed 3 years ago

bitzl commented 3 years ago

A query like /iiif/image/v2/bsb00035009_00004/0,2048,1500,1/750,/0/default.jpg may result in a target image size with a zero height. This currently leads to an internal server error, but should return a response with status code 400 according to IIIF Image API 2.1.1 specification:

If the resulting height or width is zero, then the server should return a 400 (bad request) status code.

Determing the target size happens in ImageServiceImpl:253.

Request for testing:


GET localhost:9000/image/v2/bsb00035009_00004/0,2048,1500,1/750,/0/default.jpg
