Here's a C++ code snippet of how to convert a point in client coordinates to bitmap coordinates with the 16.5 C++ Class Library interface's LBitmapWindow class.  LMyBitmapWindow is an inherited class of LBitmapWindow.


POINT LMyBitmapWindow::ClientToBitmap(POINT ptClient)
{
    POINT ptBitmap;
    CRect Dst;
    GetRects(NULL, NULL, &Dst, NULL);

    ptBitmap.x = (ptClient.x - Dst.left) * GetWidth() / Dst.Width();
    ptBitmap.y = (ptClient.y - Dst.top) * GetHeight() / Dst.Height();

    return ptBitmap;
}
