[ImageJ-devel] ImageJ-devel Digest, Vol 25, Issue 4

[Will Moore]

Hi Lee,

Just to let you know what we've done, in relation to this discussion:

In OMERO, we have a web client and have urls to define the rendered images. 
The urls encode plane (imageId, Z, T) as well as a number of optional rendering attributes.

E.g. 
http://gretzky.openmicroscopy.org.uk/webclient/render_image/26930/8/0/?c=1|204:4095$FF0000,2|204:3736$00FF00&m=c&p=normal&ia=0&q=0.9&zm=100&x=0&y=0

This is described in more detail here
http://trac.openmicroscopy.org.uk/ome/wiki/OmeroWeb/WebGateway

We also have attributes for tiling: either 'tile' zoom-level, col, row, w, h,	 E.g. tile=0,14,6,256,256
or 'region': x, y, w, h.	 E.g.  region=512,512,256,256

 Cheers,

  Will.
