Subject: TIFF 4Gb file limitation
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Sender: owner-tiff@olympiakos.com


We are using TIFF to store image data for large format, high resolution
printers
(eg. proofers, film and plate setting devices).

As these devices get larger and their resolutions get higher, the 4
Gigabyte TIFF
limitation gets dangerously close. In fact, we would already be
exceeding the 4Gb
limit if not for our use of image compression.

Is there any effort underfoot to define TIFF extensions to accomodate
files containing
more than 4 Gb of data? Specifically, the need to extend the embedded
file offsets
(IFD, tags and strip/tile offsets) to 64 bits.
