- \class TQBitmap ntqbitmap.h
- \brief The TQBitmap class provides monochrome (1-bit depth) pixmaps.
-
- \ingroup graphics
- \ingroup images
- \ingroup shared
-
- The TQBitmap class is a monochrome off-screen paint device used
- mainly for creating custom TQCursor and TQBrush objects, in
- TQPixmap::setMask() and for TQRegion.
-
- A TQBitmap is a TQPixmap with a \link TQPixmap::depth() depth\endlink
- of 1. 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). Using the \c black and \c white TQColor objects make no
- sense because the TQColor::pixel() value is not necessarily 0 for
- black and 1 for white.
-
- The TQBitmap can be transformed (translated, scaled, sheared or
- rotated) using xForm().
-
- Just like the TQPixmap class, TQBitmap is optimized by the use of
- \link shclass.html implicit sharing\endlink, so it is very
- efficient to pass TQBitmap objects as arguments.
