* Don't assume that raster can do porter duff in dfbAnders Bakken2009-07-171-5/+1
| | | | | | | PorterDuff should only be enabled if the raster engine says it is. E.g. if we're painting on a format with alpha. Reviewed-by: TrustMe
* Clean up qdirectfbpaintengine.cppAnders Bakken2009-07-151-149/+150
| | | | | | | | - Move implementation of debug functions to the bottom of the file. - Move ImageCache stuff to under QDirectFBPaintEnginePrivate - Move SurfaceCache stuff to under QDirectFBPaintEnginePrivate Reviewed-by: Shane McLaughlin <Shane.McLaughlin@trolltech.com>
* Don't force a lock in QDirectFBPaintEngine::clipAnders Bakken2009-07-152-27/+5
| | | | | | | | | | | Pretty much every paint operation on DirectFB surfaces starts with a clipping operations which until now would always cause a IDirectFBSurface->Lock(). This was to make sure QRasterBuffer::prepare had been called so QClipData::initialize() would allocate a big enough array for its spans. We can safely not make QDirectFBPaintDevice::memory() return 0 until we actually fall back. Reviewed-By: Donald <qt-info@nokia.com>
* Clean up rect/line drawing in dfb paintengineAnders Bakken2009-07-151-82/+63
| | | | | | | | Slight optimization by using the pluralized functions when possible. Also make templatized helper functions to avoid near-duplication of code for the float/int cases. Reviewed-by: Donald <qt-info@nokia.com>
* Fix off by one bug in dfbpe::drawTiledPixmapAnders Bakken2009-07-151-4/+4
| | | | | | | The drawTiledPixmap code iterated while x < right and y < bottom. This should be x <= right and y <= bottom. Reviewed-by: Donald <qt-info@nokia.com>
* Fix QDirectFBPixmap::toImageAnders Bakken2009-07-131-0/+5
| | | | | | | | | | Preallocated surfaces can currently be copied to video memory behind our back. This means that we can not use this mechanism for toImage() In later versions of DirectFB this might be possible to toggle with a flag so I'll leave the code in there #if 0'ed Reviewed-by: Donald <qt-info@nokia.com>
* Move ALPHA_PREMULTAnders Bakken2009-07-131-7/+7

* Remove QDirectFBPaintEnginePrivate::setOpacityAnders Bakken2009-07-131-9/+2
| | | | | | | The function only sets a variable anyway. Replace with: d->opacity = state()->opacity * 255 Reviewed-by: Donald <qt-info@nokia.com>

* Clean up QDirectFBPaintEngine codeAnders Bakken2009-07-131-66/+71
| | | | | | | | | | | | | | | | - Remove unnecessary copy of QTransform - Fold matrixRotShear and scale into transformationFlags. Note that transformationFlags is not a proper bitset of the types of transform but rather set to the most complex operation (from QTransform::type()) and having NegativeScale added if qMin(transform.m11(), transform.m22()) < 0 - Fix a bug whereby setState didn't call setRenderHints - Make everything more readable - Don't initialize state in QDirectFBPaintEngine::begin() QDirectFBPaintEngine::setState will be called from QPainter::begin just before QDirectFBPaintEngine::begin Reviewed-by: Donald <qt-info@nokia.com>
* Fix QDFBPaintEngine::drawTiledPixmap/fillRectAnders Bakken2009-07-101-57/+111
| | | | | | | | | Until this fix very few cases of drawTiledPixmap and fillRect(r, textureBrush) have been handled by DirectFB. This patch makes it possible to accelerate such operations. Reviewed-By: Donald <qt-info@nokia.com>

| | | | | | | | | Previously we allowed RGB32 but forced fallbacks for all drawing operations. It turns out blitting operations doesn't work right either so we'll rather just disallow this format altogether. See also 36ae58e7a6a888d3ae7bd162d59daada550bbfb1 Reviewed-by: Donald <qt-info@nokia.com>

* Refactored image cachingAnders Bakken2009-05-057-141/+147
| | | | | | | | | | | Make image caching a lot cleaner and more sensible. By default we do not cache images since creating a preallocated surface is quick and we don't really want to waste memory. In the case where the driver does not support preallocated surfaces you can enable image caching to speed up drawImage. Reviewed-by: TrustMe

| | | | | | | | | Store whether qt was built with qt3support enabled in .qmake.cache. We need this info to decide if QT3_SUPPORT should be defined when we include qimage_p.h.
