    Bmp image appears black -- TImage in Borland C++ Builder

    Hi,

    I have Borland C++ Builder 6 and develop for Windows...
    I would like to load a bitmap runtime into TImage. The user selects the file and then it should be shown via a TImage object. Using jpg images everything works just fine. Using a bmp a black rectangle appears instead of the image. (On the file system, with any image viewing tool the same image appears without problems.)

    The code is as follows:


    TPicture* picture = new TPicture;

    // I checked the following filename (debug...), it is correct
    picture->LoadFromFile( OpenPictureDialog->FileName );

    // Image is the TImage that is supposed to display the image
    Image->Picture = picture;


    Do you have any ideas?
    Thanks,
    Eszter

    With further investigation I found that the problem only concerns indexed bitmap images that are not supported by the Graphics class. But unfortunately, the images I have to display are indexed bitmaps.

    Do you know any good image converting classes for Borland C++ that could solve this problem?
