278 \preliminary-

280 \inmodule QtGui-
281 \since 4.2-
282-
283 \brief The QRasterPaintEngine class enables hardware acceleration-
284 of painting operations in Qt for Embedded Linux.-
285-
286 Note that this functionality is only available in-
287 Qt for Embedded Linux.-
288-
289 In Qt for Embedded Linux, painting is a pure software-
290 implementation. But starting with Qt 4.2, it is-
291 possible to add an accelerated graphics driver to take advantage-
292 of available hardware resources.-
293-
294 Hardware acceleration is accomplished by creating a custom screen-
295 driver, accelerating the copying from memory to the screen, and-
296 implementing a custom paint engine accelerating the various-
297 painting operations. Then a custom paint device and a custom-
298 window surface must be implemented to make-
299 Qt for Embedded Linux aware of the accelerated driver.-
300-
301 \note The QRasterPaintEngine class does not support 8-bit images.-
302 Instead, they need to be converted to a supported format, such as-
303 QImage::Format_ARGB32_Premultiplied.-
