    Level 1 of UPDF will not support any proprietary function call to an IHV library.
    That does not mean we are not thinking about it.
    The format does not support the definition of raster compression (however the reference to a predefined list), the complete replacement of raster graphic, any kind of download, raster interleaving or other candidates for a proprietary library. Depending on the interest and the will of contribution we might talk that over. I could imagine something like predefined function calls with a list of predefined parameters, a list of tasks a specific function is supposed to provide and the proper reference place for a call. Any ongoing effort in that area also depends on the acceptance and the implementation of the current UPDF level.

    I just don't want anybody to get the feeling we don't acknowledge that functionality.
    Especially in the current process where we start discussing details about raster graphic, color and halftoning we know that there is a huge amount of proprietary information an IHV is not willing to share. We will concentrate on the rather common and public information. That intention should please explain some limitations we set for ourselves in this phase.

    Our target is to provide a description for correct output, not necessarily for ultimate quality for e.g. raster graphic because of the reasons mentioned above. Any driver developer can feel free to develop a UPDF driver with additional functionality supporting the proprietary features considered IP.

    As a chair I feel responsible to keep our job on a realistic level and schedule. If more people and companies volunteer to contribute we can talk about extending our targets.
