Hello,
i wonder if it makes sense to change the image used by labels depending on zoom level.
i ask this as i have pretty large images in use:
1x ~5500x4000px
100-1000 of 128x128px
so when you zoom out i would use low res images of 64x64, 32x32 otherwise the high res 128x128
how can i achieve this, without a lot of struggle?
note: i already looked at the zoom example and noticed that icons get blocky if you zoom in a lot, while text keeps sharp

i'm confused now.
i implemented the zoom stuff with a SWT scroll component
i further have a LWS, the IFigure=content and a ZoomContainer
for me the zoom level is easily available, so thats no problem
but where do i get that graphicaleditpart?
