Large Panorama Formats

[Paul Elliott]

Hi,
This is probably a fairly basic question. What output format are people using for large panoramas (64K X 32K ) ?
I've hit the file size limtitation on Tiff. I'm not sure about PNG as I thought it was more for small web images, in any case large PNG outputs seem to fail for me ( I could look deeper into this if PNG is considered appropriate).
I use Krpano for viewing which can take larger file formats; but without going to perhaps PTGui I can't generate them.
Thanks,
Paul

PNG should have no size limitation in this range. So it should be possible to use. (But I have no own experience, my panos are small.) But I found same reports that not all programs can handle such big PNG images.

Concerning TIFF, the development versions of Hugin and enblend/enfuse are capable to generate BigTIFF files and can so overcome the TIFF file size limitation.

(So you will need the versions from both repositories. In both cases the bigtiff switch have to added manually, either on the command line or in the user defined output sequence. It is not added automatically.)

Hi Thomas,
Thanks for the reply, I'll take a look at the development versions. I didn't realised work had been done on BigTIFF. I haven't managed to get a large file to output in PNG yet, I'm probably doing something wrong. I can get outputs in JPEG but would rather use a lossless file for the further processing so BigTiff may be an answer. Using the command line for final output is OK with me so I think you may have solved it.
Thanks,
Paul
