Story points rate the relative effort of work in a Fibonacci-like format: 0, 0.5, 1, 2, 3, 5, 8, 13, 20, 40, 100. Each team will estimate work on a slightly different scale, which means the values in this field are likely only meaningful to the team that owns the Buganizer component in which the issue resides.

Description
Exif data is stored in a JPEG
APP1
segment which has max size of2^16 = 65536 bytes
.Some devices (e.g. Samsung A32) create images with quite large embedded thumbnails that take up nearly all these bytes [1]. When we then try and save additional exif data we currently produce a corrupt jpeg file (version 1.3.6). The short-term fix for that bug avoids the corruption by throwing an exception from
saveAttributes
instead.When experimenting with adds a second . We could investigate adding similar behaviour to
exiftool
to recreate the same problem, itAPP1
segmentExifInterface
. Before we do this we need to understand how well supported this file structure is across the ecosystem. It would also require significant rearchitecting ofExifInterface
because the logic it uses to lay out the structure of the theAPP1
segment is quite complicated, and not 'aware' of splitting into multiple segments.[1] The Samsung A32 in particular seems to always create a 64,000 byte thumbnail, no matter what the content of the image is, whereas all other devices I tested (several other Samsungs & Pixel 5) produce different size thumbnails for different images (which makes sense, since jpeg compression is heavily content-dependent).
