runtime watermark

Hello!

Does anyone know a viable way of creating a watermark over the panorama images at runtime? I mean one that would be at least moderately safe. Adding a simple plugin/layer doesn't work since it can be easily removed by anyone with a little programming knowledge. Some way perhaps to add text directly on top of the image, using the webgl api maybe? Sorry I'm not really proficient in it.

Thanks in advance!

why is a layer a problem?
and what do you want to protect?
the xml code? the pano image?

you load a watermark png in a layer
if the png cant load you dont start the tour
your pano is multires, so that the complete pic cant get extracted
you encrypt your xml and the png, so that it cant get exchanged
done

if somebody is able to hack that,
you cant stop him anyway.

I want to protect the image, but preferably without hard-burning the watermark on the source, also it'd be great if I could use a dynamically generated (variable) text as the watermark. The layer is a problem because whoever has just basic knowledge of developer tools for example (no need to be a hardcore hacker), can rather easily find and remove the layer. This is something you couldn't do in flash, but sadly in HTML it's an issue...

ok, but like that you can only get the canvas, not the full panorama.

i will release a webgl postprocessing plugin soon, so i could create a webgl watermark plugin, too.
but this would be custom work as this not needed by most of the people i guess... (?)

best, index
