Bug: Render with No Active Channels — at Version 2

Reported by: saloynton Owned by: cxallan
Priority: major Milestone: OMERO-Beta4.4
Component: Services Version: n.a.

Description (last modified by wmoore)

Split-view of thumbnails, missing images shown for images in dataset with no blue channels. Should have a space filler generated of correct size to preserve the layout.

  • OMERO-merge-blue - Build # 157

This is due to the fact that the rendering Engine throws an exception if you turn off all the channels then try to render

i = conn.getObject("Image", 145)
pid = i.getPixelsId()
re = conn.createRenderingEngine()
pd = omero.romio.PlaneDef()
pd.z = 10
pd.t = 0
re.renderCompressed(pd)       # OK
re.setActive(0, False)              # This is a single-channel image

  File "/Users/will/Desktop/OMERO/dist/lib/python/omero_api_RenderingEngine_ice.py", line 326, in renderCompressed
    return _M_omero.api.RenderingEngine._op_renderCompressed.invoke(self, ((_def, ), _ctx))
omero.ApiUsageException: exception ::omero::ApiUsageException
    serverStackTrace = ome.conditions.ApiUsageException: No active channel bindings found.
