I need to display huge number of "elements" in NSView (1000-2000).
These elements are generally made of high resolution image files
with some fancy drawing around them. These elements may vary from
size 300 X 270 to 4280 X 3500.
First I made use of NSView's for "elements", I abandoned the idea
because I was supposed to connect some elements with lines,
obviously line drawing was going behind the elements .
Secondly I tried with CALayer's and I have a problem of GPU
constraint for the resolutions I mentioned.(I tried optimizing, by
only displaying required layer in the View's visible part ,that too
didn't help much)
Is there any other way of approach, or should I be making use of
one of the ways I mentioned ?
In addition to Graham's comments in a previous reply, I'd also
suggest that, depending on what your view does, to generate a smaller
thumbnail to represent the full-sized image. This both reduces your
memory footprint as well as improving drawing speed. If the thumbnail
size is dependent upon the view size, you could either invalidate
your thumbnail cache when the view size changes or choose a maximum
thumbnail size that you just scale appropriately.
