* Included ARM NEON optimizations from pixman in Qt.Samuel Rødal2010-03-261-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the N900 16 bit text blending is 30 - 50 % faster, and ARGB32PM on RGB16 image blending now runs in 1/10th of the time it used to. We now make ARGB32PM the default pixmap format for alpha pixmaps instead of ARGB8565PM which is unaligned and bad for performance. The relevant numbers: Mostly opaque pixels: ARGB24 on ARGB24 using QPainter..................: 336,813033 ARGB32 on ARGB32 using QPainter.................: 18,419387 RGB16 on ARGB24 using QPainter..................: 167,301014 RGB16 on ARGB32 using QPainter..................: 17,279372 ARGB24 on RGB16 using QPainter..................: 35,100147 ARGB32PM on RGB16 using QPainter................: 15,924256 No opaque pixels: ARGB24 on ARGB24 using QPainter..................: 412,190765 ARGB32 on ARGB32 using QPainter.................: 16,818389 RGB16 on ARGB24 using QPainter..................: 170,957878 RGB16 on ARGB32 using QPainter..................: 16,742984 ARGB24 on RGB16 using QPainter..................: 93,600482 ARGB32PM on RGB16 using QPainter................: 15,999310 So switching to ARGB32PM should give a boost in all areas.

* | Using qreal more consistently in code (prevent misuse of double)Aleksandar Sasha Babic2009-11-061-9/+9
|/ | | | | | | | | | | | | | | | | | | | | | | | | We want to force use of qreal where possible. This can lead to better performance on platforms where qreal -> float (i.e. ARM). To achieve this we: 1. changed from 'double' to 'qreal', where justified 2. using qreal() to intialize constants, where justified 3. adding helper functions that are overloaded for qreal like qAtan2(), qAcos(), qFabs() ... 4. defining QT_USE_MATH_H_FLOATS for Symbian platform In addtion we used opportunity to improve code with some small things 5. converting divisions to multiplications (i.e. '/ 2.0' -> '* qreal(0.5)') 6. defining new constants (i.e. 'Q_PI / 180.0' -> 'Q_PI180') 7. declaring variables as 'const', where justified Reviewed-by: Andreas Aardal Hanssen Reviewed-by: Gunnar Sletta Reviewed-by: Jan-Arve Reviewed-by: Kim Motoyoshi Kalland Reviewed-by: Alessandro Portale Reviewed-by: Janne Koskinen

| * Fixed drawImage() so that it doesn't sample outside the source image.Kim Motoyoshi Kalland2009-07-281-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In qt_scale_image_16bit() and qt_scale_image_32bit(), when a sample point was located on the border between two pixels in the source image, the sample point was rounded up instead of down. If a sample point was exactly on the bottom or right edge of the source image, the function would therefore sample a pixel outside the image. Because of how the target rectangle is rounded, a sample point will never be exactly on the top or left edge of the source image, so we will not get a similar problem there.
