stack, not the final image. So we cannot take the projection and filter that<br>
(we could do that, as an optimization, in the case where there's only one<br>
layer), but have to filter the layer, recomposite and redisplay.</blockquote><div>Now i see.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
We don't have something like a pyramid representation of layers (yet)</blockquote><div><br>Emm.. Can i read about that pyramid anywhere?<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
where we could filter at the zoom level nearest to the actual zoom level. That would be<br>
one solution, sort of.</blockquote><div><br>Why do we need many thumbs? And why filtering the nearest one? Why not have only two layer representations: original and current zoom level? Zoomed copy could (?) be used by projection (keeping in mind interpolation).<br>

have to redesign this class), is setting a region of interest on the<br>
projection; this would mean that for preview, only the visible part of an<br>
image is filtered, recomposited and redisplayed.</blockquote><div><br>I guess it's not very useful for filters as most of them work on the whole image (i don't speak about tools). In Krita1.6 we had an ability to see scaled down output of filter in it's dialog. I could add one more complaint about that=) It was quite bad :)<br>
