Subject: Zoom / Scale

---

Hi every1..

i'm trying to implement zoom capability in my app so i know how to do it,
but i ran into some problems :)

For zoom i use simple pixel replication (if it's called like that) :)

newsize = x * oldsize..

when i zoom out the picture, everything is ok.. but when i zoom in the
picture, and if i zoom very large pictures (1280x1024) then i run out of
memory :) i know why i get that message.. but how to do the zoom and not to
run out of memory...

one thought i came with is not to zoom entire picture, but to zoom only the
part that is currently visible on the screen..

Is there a better way to do a zoom on a picture?

I must say that no special filers should be applied to zoom .. simple image
zooming is what i need..
