Turn off slow TIFF compression by default #9

Closed igorpisarev closed 5 years ago

igorpisarev commented 5 years ago

It's been reported that writing TIFF images compressed with LZW is very slow, in particular on network file systems. For this reason, use of LZW compression is now discouraged, and the default behavior is now to write uncompressed data.

The currently integrated LZW compression is based on bio-formats_plugins. Need to find and benchmark other TIFF compression implementations (will have to make sure that resulting images are compatible with Fiji and other common image processing applications).
