[livesupport-dev] graphics for the GUI
  • Akos,

    Sangita and I are working on the graphics now, and I've
    encountered a question that you might know how to answer -

    the palette design assumes curved edges, which necessitates
    transparency, and I don't know how to produce a graphic that is
    transparent against all background colors - normally we produce
    graphics to be transparent against a specific color, but in this case
    that won't work, because we have to take into consideration all the
    possible desktop colors.. is this a characteristic of programming
    that you can address? - it may be that we need to make hard edges
    to solve this problem as a last resort.

    I'm going to look into this further, but I thought I'd check with you
    to see if you've encountered this issue before.

    Thanks in advance,


    Charles

    Sorry for replying so late. As far as I know, the GUI library we're
    planning to use, GTK+, supports the PNG file format, which has
    transparency support.

    Now I've checked on this, and it is totally possible. See the attached
    screenshot, it's the wheelborrow sample of the GUI API (GTK--) we're
    using. It is simply superimposed on this very e-mail composition window
    I'm writing the text on.

    So, go ahead with the transparent graphic approach..
