You can simply set the ev parameter (lens tab, photometric) of an image to something above 16 and should be able to see the results. Rewriting the image has the nice property that it is completely independent of the calling code, but unfortunately its a bit costly. It would be possible to compute the scaling factor without rewriting the image, but this would require that the max of the image is computed somewhere inside the exportImage() functions and not in the codec itself. However, the vigra impex code is quite messy and hard to understand. > 2.) added support for different compression algorithms.

I think enblend handles the compression arguments straight to vigra. With hugin it should be possible to modify the .pto file and set the type by changing #hugin_outputImageTypeHDRCompression <newcomp> ciao Pablo --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
