[ome-users] Image too big for OMERO.figure

[William Moore]

Hi Kai,

 Unfortunately OMERO.figure doesn’t support tile-based viewing of big images (in the way that the web client viewer does).

See discussion at https://www.openmicroscopy.org/community/viewtopic.php?f=4&t=7873&p=16073 <https://www.openmicroscopy.org/community/viewtopic.php?f=4&t=7873&p=16073>

Because we are limited to working with single planes, we have a hard-coded limit of max size, which is currently
equivalent to 5k x 5k, see https://github.com/ome/figure/blob/v1.2.0/static/figure-1.2.0.js#L3679 <https://github.com/ome/figure/blob/v1.2.0/static/figure-1.2.0.js#L3679>

Since your image is 10k x 11k I don’t think that tweaking this cut-off is going to help, since rendering the whole image as
a single plane would likely be too slow & use a lot of memory.

Other work-arounds would be to crop the image prior to adding to OMERO.figure, or down-sampling (before import to OMERO).
These are discussed a bit at the link above.

I would eventually like to support proper tile-based viewing of big images in OMERO.figure, but I’m afraid that won’t happen
in the foreseeable future,

 Regards,

  Will.
