with Rebol, you are provided with closed feature set. It means, you can
load bmp, jpg, gif, gifanim, png and save as bmp and png - that should
provide you with some means of compression. If you want to try to do
something on your own in rebol level, I fear you will be slow. XxY image
means lots of pixels to traverse using some loop + some calculations ....
You can, however, link Rebol to libraries. It requires /Pro license
though (or new SDK, to allow you to encap and release your app, if you
want to provide it for free).
But, last two or so months proved, that not having free library and
shell components in free versions, is holding further rebol accpetance.
I tried to defend Rebol (mainly because I have different position and
some concrete plans for my rebol usage, so I don't hesitate to byu
commercial versions), but it really showed as a show-stopper for rebol.
It is long time we (ehm, especially me :-) suggest RT to change their
opinion, because I am not sure that /Pro sales outweight the profit,
which could be gained, if those components would be free, or at least
tied to royalty shceme = free for development and usage ... and if you
charge for your work, then royalty would be payed back to RT ... maybe
that way more library interfaces would appear and overall benefit would
be higher ... but who knows ...
