I was planning to use server code to tile the large images and then use one of a number of JavaScript   libraries to render.  Any browser should work without extensions . Jim did this with visigene in the genome browser years ago.

Hi, Robert

As far as I know, all browsers besides Safari aren't set up to render tiff files by default. Are you using Safari to display the files in Galaxy?

There are extensions for Firefox and Chrome that will allow you to display these files. Would that be an option?

As a side note: creating, saving, and manipulating images and thumbnails would require Galaxy including a server side image processing library as a dependency. I'd like to do this at some point in the future as it would allow us other advantages too.

Thanks,

Carl

Do you know a fast way to open large tiff files in galaxy ? The sniffer recognizes the type, but clicking on the eyeball on a large 82mb file just hangs.
Downloading the file and opening in preview does work but it is clunky. Perhaps storing a low res version that would be display when clicking the eyeball would speed access.
