    PNG problem

    I've got some strange goings on with some png files. In playback they work fine but after exporting to SWF they are losing their transparency. Anyone else had the same problem or has a solution?

    Hi Bob. The file is a bit big to send but if you go to http://www.cratepages.com/transvalnew/index.swf you can see the two files. They are both png 8 (the two busses). if you open http://www.cratepages.com/transvalnew then you'll find the fun file "index.fun. it's strange because it isn't happening to any of the other images and it wasn't happening before I switched to the latest KM version. Cheers.

    If you zip it, I bet it isn't big. I need the image to test. I don't remember touching any image related code in the last version.

    I am still waiting for someone to send me an example.

    A png 24 bit is no better than a regular bitmap. So convert to bmp format.

    Yes, but...

    Maybe I am wrong, but as far as i know .bmp supports no transparancy...
    Maybe total off-topic...

    but tried to give a new view to it.

    nevertheless, i´lll stuck on all this
    greetings , stefan

    P.S.: 24bit means -some- more than 256col... 4get my post... For your fun I don´t delete it !

    24 bit png doesn't support transparency - only 8 bit and 32 bit.

    24 bit PNG does support transparency but some IE browsers do not render the image properly. There is an easy work around at the following link http://css.weblogsinc.com/entry/1234000933031938/ Not sure if it will work in KoolMoves.

    Interlacing has cleared up an image problem I have w/ PNGs (ie, in Photoshop, select interlaced option).

    False !

    In few words:
    There're 2 structures able to carry the alpha channnel:
    1) 8 bit PNG or GIF (max. 255 colors, 1 bit transparency)
    2) 32 bit PNG (and few other formats).
    Now the sticky part: there're 2 kind of 32bit PNGs:
    RGBA8881 (1 bit transparency)
    RGBA8888 (255 levels of transparency - aka "transparent layer", useful for gradients)
    I use PhotoShop since I can't remember, but it has an "original" way to deal with transparent images.
    To be out of troubles, be sure that the transparent area is BLACK (switch off the transparency to check out).
    cheers
