If a pixmap with a depth greater than 1 is assigned to a - bitmap, the bitmap will be dithered automatically. A TQBitmap is - guaranteed to always have the depth 1, unless it is - TQPixmap::isNull() which has depth 0. - - When drawing in a TQBitmap (or TQPixmap with depth 1), we recommend - using the TQColor objects \c TQt::color0 and \c TQt::color1. - Painting with \c color0 sets the bitmap bits to 0, and painting - with \c color1 sets the bits to 1. For a bitmap, 0-bits indicate - background (or transparent) and 1-bits indicate foreground (or - opaque).
