[REBOL] Re: Another "External library" problem..

Hi Romano,
Your method is not suitable for this purpose:
1) allocation of block of struct! containing for example 512x512 * 4 bytes
of chars! takes more than 30MB of memory!!
2)doing for example:
img: make image! reduce [512x512 third z/data]
30 and more times per second gives you poor performance
I meant any method which avoid ani image! data manipulation(like reduce in
this case) from Rebol side. You only make image! referencing to the pointer
you got from the external C function...then you need only do a SHOW to
refresh face which contains this image with data which are frequently
changed by extenral rendering library(in this case OpenGL)
I think this is not possible but anyway, any idas are welcome.
regards,
Cyphre
