It seems there's a calculation error in 
loci.formats.services.JPEGTurboServiceImpl.java similar to one described 
here: 
http://lists.openmicroscopy.org.uk/pipermail/ome-users/2013-September/003940.html

Lines 235 and 239 reads:

235: tileBoundary.height = row < yTiles - 1 ? tileDim : imageHeight % 
tileDim;
239: tileBoundary.width = col < xTiles - 1 ? tileDim : imageWidth % tileDim;

If I change the lines to these lines below, I don't see the black area 
on tile.jpg:

235: tileBoundary.height = row < yTiles - 1 ? tileDim : imageHeight - 
(tileDim*row);
239: tileBoundary.width = col < xTiles - 1 ? tileDim : imageWidth - 
(tileDim*col);

I hope this is useful.

This is the second time I suggest a change on the mailing list. Is there 
somewhere more appropriate to suggest changes to the code?
