Interacting with large images?

[paul womack]

I don't mind my laptop
taking a few hours to crunch to large mosaic-panoramas
(AKA gigapixel photograph).

However, for viewing and using such images,
I would like it to be decently interactive.

What software tools are people using
to scroll/zoom very large images?

in my case very large is 33054x17293 on a machine with 8Gb.

Most desktop image viewers aren't happy...

I found this:
http://iipimage.sourceforge.net/
which appears to be the sort of thing galleries
and archives might use.

Pyramidal image formats would seem to be part
of any practical solution.

But setting it up for "local" use looks feasible,
but more work than I really want.

Any suggestions (I'm on Ubuntu 14.04) ?

I've been always using the nip2 frontent to VIPS [1]. It's mainly a
complex image processing framework, but it is also blazingly fast
viewer for images that are much larger than RAM.

Like stativ I use VIPs but only to generate image tiles. http://libvips.blogspot.co.uk/2013/03/making-deepzoom-zoomify-and-google-maps.html

I then have a script that creates a web page with correct parameters (new directory name etc) using leaflet . http://leafletjs.com

It is very fast to display and zoom large images.

Is there a way to blend the images directly to tiles, like gigatile would do, using VIPS?

I'm trying to use gigagile, but I'm getting an error and also have read that it lets visible lines/seams between tiles.

Here is the last gigatile error:

(many equal lines before...)

gmaptemplate --title parcial02rtrt --initialzoom 0 --apikey PUTAPIKEYHERE --prefix parcial02rtrt --maxzoom 4 --maxzoomp1 5 --minres 0 > parcial02rtrt.html

Not sure about this, what version of Perl do you have?

I thought i should post a version of the script  ( see attachment ); 

usage:  minimalpano.sh filename.jpg

Requires VIPS
