Export filter included in ExportService?

Question

Hi, I wrote a little export filter. Then I wrote a simple ExportService, both are declared in the Info.lua file.
Now, I need that when the user select my ExportService, my ExportFilter is automatically included (not having to manually enable it in the Postprocess action window and when switching to another export preset and back to my ExportService, it disappears).
How to do that?
Thanks a lot

Oh shoot ... didn't realize you were using shouldRenderPhoto. That function isn't supported in the export service provider API.
I haven't tested this recently, but I think you can do what you're trying to do in your processRenderedPhotos function.
Something like:
function processRenderedPhotos( functionContext, exportContext )
    exportContext.exportSession:removePhoto( unwantedPhoto )
          -- This has to proceed your
          -- exportContext:renditions{...} call
end
Note: This is just taken off the cuff from a sample plug-in I have around. I haven't tested it, so it might need some tweaking, but the basic principle should be right.
Hope this helps ...
P.S. You should be able to call :removePhoto multiple times (prior to the :renditions call) to remove multiple photos.
