I tried to open a 4800x3600 24bit PNG file, but it made Pd crash/suddenly quit.

here I load my patch, the relevant connections are:
[bng]
|
[openpanel]
|
[open $1, bang(
|
[@store]
I click the [bng], select my 4800x3600 24bit PNG file and...
Pd: signal 6 socket receive error: Connection reset by peer (104)
...no more Pd.
A nicer error message would be, well, nice, and not aborting instantly would be even nicer.
I guess this is because...
4800 * 3600 * 3 (channels) * 4 (grids are int32 by default) ~=~ 200MB
...and I only have 256MB RAM.
Is there any way to load the image directly into a (H,W,3)(uint8) grid? And would [@store] store it like that?
Simple solution for now - resize source image to something that fits in memory.
Ideal solution - lots and lots of RAM.
Anyone wanna donate me some memory modules - it was my birthday on Monday, call it a late present! ;-)
