I'll try tomorrow.
Actually I need some image processing function (eg. lightening) in image3. My
original post is not well written because the large space overhead is not
directly related to image3, but rather to J interpreter itself.

When I use image3 addon to read a large jpeg, it raise a memory limit error, (I
lower the memory limit to avoid swap). So I use 7!:5 to measure the space in
bytes used by the named objects,
B=: 100 200 3$2
7!:5 <'B'
262144
*/4 100 200 3
240000
B=: 1000 2000 3$2
7!:5 <'B'
33554432
*/4 1000 2000 3
24000000
B=: 2848 4288 3$2
7!:5 <'B'
268435456
*/4 2848 4288 3
146546688
It requires nearly double amount of space for large object. Can this be
improved?
Could you try for comparison the platimg addon to
see if it can handle the large jpegs that you have.
Thanks.
