    How have you edited it? Have you added layers or converted it to 16 bits?

    Hi,
    What are Targas used for?
    Thanks,

    my husband uses them to make files for his NASCAR race sim
    you can paint cars in a PS layered template but they have to be flattened
    and save as >>tga to be seen in the game interface

    Targa-format files are commonly used for texture maps for 3D modeling
    and rendering applications. A Targa file can contain an alpha channel
    which controls transparency, and the rendering program "paints" a 3D
    image by wrapping the Targa file around it. Transparent areas of the
    targa file show the 3D model beneath.

    Hi,
    Is the alpha channel the same thing as a displacement map? Can an
    alpha channel used for transparency information also be used for
    displacement information at the same time? Do Targas only allow for a
    single alpha channel?

    Thanks,
    Ron

    Nope. Different animals completely. Alpha indicates per pixel transparency.
    In 8 bit 255 means 100% opaque. A displacement map is a per pixel value to
    shift the location of the pixel, remaping the image to a new, usually
    warped, shape.If two values are used, you can displace in two dimensions.

    I suppose it's possible, but it's probably never done. The edges of an
    object will have an alpha less than 100%, and this would cause those pixels
    to be displaced less than pixels in the middle of the object. The result
    would be a sort of skewed "punch out" of the object. It's more common to
    use modified brightness information as a displacement map. One example is
    a wavy flag effect where the waves correspond to the shaded colors of the
    flag.

    > Do Targas only allow for a single alpha channel?

    I believe so. Targa got in there first with high quality video overlays for
    the PC, so some of their file formats are still being used. The file format
    itself is a dead end.

    I see. It seems like any image format worth its salt would include a
    transparency channel. And maybe a few map channels too.
    Come to think of it, PSD and TIF are some pretty powerful protocols to
    be able to contain all the color, style, layer, text, vector and
    channel information that PS generates.

    Thanks,
    Ron

    This is only the 2D stuff too. Wait til you start digging into the
    rendering side of things. It's the difference between understanding the
    opcode set of a simple machine, versus an OS.

    Ron,

    Aside from the 2-D texture mapping, they are still used by many video programs
    for effects, menus, etc. Folk, using MACs with Final Cut Pro for NLE (Non-
    Linear Editing) use them as still images quite often. I see them for effects
    and transitions in NLE apps.

    I do not know FCP, but have had several instances where vid-editors needed
    TGAs, in lieu of TIFFs for inclusion in video productions. No problem on my
    end converting TIFFs and PSDs to TGAs. Only limitation that I saw was that
    Bridge would not preview TGAs on my XP-box, though ThumbsPlus did, and I'll
    bet that Irfanview would too. At the time, I inquired on the Adobe Forum, and
    was told that it was a limitation of Bridge on the Win OS. Do not know how
    ThumbsPlus got around that, but it was not something that Adobe could do -
    then.

    To the OP, I think that the others are right-on in their comments on 16-bit,
    or Layers. A little more info on how the file came to your computer, i.e.
    format, etc., and the editing that you did to the file, might be able to
    explain where the problem is.

    OR you can cheat and use this and from an older version of PS and see
    thumbnails of all the psd and tga in WINDOWS explorer!!!!!

    file is called
    PSICON.DLL

    FWIW hubby and I used this over two years now on WIN XP PRO SP2 no issues,
    crashes etc

    from the readme::
    Photoshop CS - Windows Explorer Thumbnail Enable Patch
    ** This is not an Official Patch, use at your own risk. **
    ** Follow the Instructions carefully. **


    1. Copy psicon.dll to the following directory:
    C:\Program Files\Common Files\Adobe\Shell\

    2. Double-click Install.reg, and merge it into your registry.

    3. Celebrate, you're Done!
