Dear all,

I used to work on my old computer with "large" NDPI files from Hamamatsu
Nanozoomer acquisitions.
To treat this kind of large files, I use NDPI tools plugin :
- PreviewNDPI
- Selection of small ROI (I asume entire image too big)
- Extract to TIFF
- then, my processing.

Selection of ROIs is time consuming.
I actually use new 64bits Win7 32GbRAM 3GbRAM Graphic Card's computer.
Well, if I want to convert an _entire NDPI image_ to tiff (full
resolution), I only get this error message : "Illegal page requested
from a TIFF file."

I tried to open it with LOCI, full resolution (46080*41728, 3 planes), I
got
"java.lang.ArrayIndexOutOfBoundsException: 1473511424" error.
The 11520*10432 resolution open, but the quality is not here.

Could anyone tell me what are the limits ?

Thanks all,
