Image render scale

Hello, is there posibility to set same image scale for all images? For example now every image loads in 3,13 % of original size. But 50% is needed on start - it`s caused by better performance - large VSI files.

thx in advance

Thank you, this is certainly something into which we should look if it is significantly affecting performance. Which client are you using, Web or Insight?

Depending on your version of OMERO, the web image viewer has a setting that can specify the initial zoom level.

If you're using web, try setting this option on the server, with a range of 0 - 5. Then stop and restart your web server and refresh/open an image viewer again:

Code: Select all
$ bin/omero config set omero.web.viewer.initial_zoom_level 4


This option is not yet available in Insight, but could be added if this is what you need (also, any feedback you have about this setting in the web would be useful).

Cheers,

Will.

no diffrence to performance

$ bin/omero config set omero.web.viewer.initial_zoom_level 4


Thanks, that realy helped. Now my images loads in 12.50%, 25% or 50% of original size and performance is much better - image tiles loads faster. Is there any chance to make this custom to insight client? - maybe in 5.0 version

I use omero 4.4.9, my images are from 30000x30000 to 80000x100000 pixels big

Best regards
Robert

Hi,

I've created a ticket for implementing the same functionality in Insight: https://trac.openmicroscopy.org.uk/ome/ticket/11859

Cheers,

Will.
