Width limit for PNG

[Gugu7264]

Hey! I'm using this library to generate huge images (128000 x 96000 for example), and I'm encountering the problem of max 65k pixels.
After some search, it seems to be due to chunk limit which is of this size, but I also found that PNG do not have width or height limit...
Do you think there is any way this could be implemented, or maybe you have done more research than I have and you've got a reason why there's a limit?

Thanks in advance :)

After some more research, this might be possible using multiple IDAT chunks? Let me know what you think :)

ok, data chunks are capped at 2^31 bytes which is the max addressible by 32-bits
your example likely requires 2 IDAT chunks as you suggested
