Hello,
It is certainly possible. You can do this in the usual way, 2.5 fully supports linear colorspaces and floating point formats. You have 3 different floating point depths double : 64 bits float : 32 bits half : 16 bits. You only need to provide the data in floating point and specify the right format, for example TYPE_RGB_FLT or TYPE_GRAY_HALF_FLT. When using floating point formats on both input and output, lcms switches to a "quality mode" which is significantly slower, but way more precise. Linear mode needs this mode to avoid artifacts.
