{Implicit Data Sharing} documentation. QPixmap objects can also be
streamed.
- Depending on the system, QPixmap is stored using a RGB32 or a
- premultiplied alpha format. If the image has an alpha channel, and
- if the system allows, the preferred format is premultiplied alpha.
- Note also that QPixmap, unlike QImage, may be hardware dependent.
- On X11, Mac and Symbian, a QPixmap is stored on the server side while
- a QImage is stored on the client side (on Windows, these two classes
- have an equivalent internal representation, i.e. both QImage and
- QPixmap are stored on the client side and don't use any GDI
- resources).
-
Note that the pixel data in a pixmap is internal and is managed by
the underlying window system. Because QPixmap is a QPaintDevice
subclass, QPainter can be used to draw directly onto pixmaps.
