Hi there, there are new tiff image formats readable now. Basically, the new io lib supports up to 4 channels with 1, 2, 4, 6, 8, 10, 12, 14, 16, 24, 32, 64 bits depths. Right now a multi-channel image only supports the same channel depth for all channels. For instance for a rgb10_image_t all channels are 10 bits deep. I would really like to support multi-depths channels but unfortunately there would be too many template instantiations. I would like to ask the boost experts to have a look at my lib and to give some advise on how to deal with it. Also, is there someone that can compile my code on a Linux machine? I don't have access to it and would like to know if all is kosher. Thanks, Christian
