Creating white text

    I need to create a bmp file with "white" text that I can superimpose on
    a bmp image file (I use a program that merges two bmp files). If I use
    a transparent canvas and set the color to white, the text is invisible.

    What am I missing here?

    Are you flattening the image before saving as a bmp?

    Where is the type not visible? In Photoshop or the other program? What
    is the Blending Mode?

    What are you setting to white, the canvas or the type? Or both?

    BMP files don't save transparency - instead you get white where the file
    would have been transparent. Even if that didn't get you, it's likely that
    your merging program assumes that pure white is transparent as well.

    Being a photoshop person, and as long as you are already creating the text
    in Photoshop, I'd suggest you ditch your bmp merger and create a Photoshop
    action to merge the text. You'll have other effects such as drop shadow
    available that way as well.

    If you want to stick with your bmp utility, though, one solution would be to
    use slightly off-white text. Try darkening the text a bit to see if that
    does the trick. You may be able to use 254,254, 254 for your text, but you
    may want to start with a brightness of rgb 250,250,250 or so to avoid any
    issues with roundoff error.

    Mike -

    It must have to do with transparency and bmp files - I need to look at
    the code and determine what is happening.

    The reason I use the program that merges the two files is because it
    does a complete directory: converts the jpg photo images (after I have
    worked on them with PS), resizes them to thumbnails are to a specified
    size for the Web, merges the copyright, puts a border around them and a
    drop shadow and creates the HTML (http://209.204.172.137/dictionary/ ).

    Now, I tried black with 100% opacity and the anti-alias (PS 7) is
    "smooth". I am getting what appears to be aliasing.

    Is that correct?

    This is a white matte around the black text. One workaround is to use a 50%
    gray background, which will cover most of the problem most of the time.

    Another solution is to turn off anti-aliasing. This will give you jaggies,
    but it will look a lot better than what you're getting now. Still another
    solution would be to add the text before resizing the thumbnail, if you have
    that option.

    The ultimate solution is to use an alpha channel to get a clean anti-aliased
    mask, but that would require the use of full Photoshop, or some other
    alpha-aware imaging app.
