289 \brief The QRasterPaintEngine class enables hardware acceleration-
290 of painting operations in Qt for Embedded Linux.-
291-
292 Note that this functionality is only available in-
293 Qt for Embedded Linux.-
294-
295 In Qt for Embedded Linux, painting is a pure software-
296 implementation. But starting with Qt 4.2, it is-
297 possible to add an accelerated graphics driver to take advantage-
298 of available hardware resources.-
299-
300 Hardware acceleration is accomplished by creating a custom screen-
301 driver, accelerating the copying from memory to the screen, and-
302 implementing a custom paint engine accelerating the various-
303 painting operations. Then a custom paint device and a custom-
304 window surface must be implemented to make-
305 Qt for Embedded Linux aware of the accelerated driver.-
306-
307 \note The QRasterPaintEngine class does not support 8-bit images.-
308 Instead, they need to be converted to a supported format, such as-
309 QImage::Format_ARGB32_Premultiplied.-
