i dont know about any such utiltiy right
now,
but writing one on your own would not be that
complex:
you just have to load the 4 tiles and then copy
the raw
pixels into a single buffer that once again
gets encoded.
for this using an openexr library would be all
you need.
(if it were friday now, i would say, drop me a note
and
i will try my very best on this topic until next
monday.)
for JPEG with micro tiles encoding (some
16x16, you
might see them when encoding with too much
loss)
it would be even possible to just join the micro
tiles
without even a need for decoding them. That
needs
deeper knowledge of image format and might not
work
if the width or height arent multiple of micro tile
size.
i am not sure if
something similar to the second method
will be allowed for some/all EXR format
encodings.
