  • Nemo at ROUGOL, Monday 20th March 2023

    From ROUGOL@21:1/5 to All on Sat Mar 18 03:55:35 2023
    The next meeting of the RISC OS User Group Of London will be:

    MetaSprite, IFR, and more
    Presented by Nemo

    Monday 20th March 2023, 7:45pm

    Online via Zoom, meeting open from 7.30pm

    https://rougol.jellybaby.net/meetings/


    Nemo has been in and out of the RISC OS world for many years, but even
    when keeping his head down he has continued to use RISC OS daily on
    VirtualRPC, and has developed many useful tools, patches, and upgrades for
    the OS. Recently he has been been working on a reimplementation (and enhancement) of RISC OS Select's Image File Rendering (IFR) system. It is
    not ready for release yet, but some of the related tech is already
    available and will be demonstrated during the meeting.

    Nemo will take us on a journey through MetaSprite, CompressedImage, IFR,
    and the new Qoi lossless compression bitimage format, which are all
    connected via RISC OS tech. In other words they're not just things running
    on RO, but are woven into RO at the API level. CompressedImage sits on
    SpriteV, uses MetaSprite + another interface to recognise (and generalise) Acorn's sprite compression scheme which it implements via IFR that, in the example case, allows a Qoi-compressed sprite to be displayed, gamma
    corrected by interrogating the Monitor module.
    (That will all make more sense by the end of the meeting!)
