* Update copyright headersAkseli Salovaara2015-03-311-13/+13
| | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Change-Id: I7e3e96183e073877b46bc8071b2ccae19e69426b Reviewed-by: Jani Heikkinen <jani.heikkinen@theqtcompany.com>
* Avoid out of bounds memory reads when scaling imagesv4.8.6Lars Knoll2014-04-031-2/+2
| | | | | | | | | | | | | | | | | | The calculation of the width/height required for the scaling algorithm was prone to floating point rounding issues, where the lower value got rounded down, the higher one rounded up. This could lead to a situation where we iterated over one more line/pixel in the line than we have in the source image. Correct this by passing the dimension of the source image into the function and bounds checking the values before iterating.

| | | | | | | | | | | | | - Replace Nokia contact email address with Qt Project website. - Remove "All rights reserved" line from license headers. As in the past, to avoid rewriting various autotests that contain line-number information, an extra blank line has been inserted at the end of the license text to ensure that this commit does not change the total number of lines in the license header.

* Use NEON and preloading for 16 bit small / medium sized image blits.Samuel Rødal2010-09-011-0/+5
| | | | | | | | | | | | | | This gives a nice speedup for blitting of small and medium sized images by using preloading and avoiding function call overhead to memcpy for each scanline. For larger image widths memcpy becomes more efficient. Speedups of up to 40 % for 64 pixel wide images were measured. For image widths between 2 and 16 the speedup ranges between 12 % and 28 %.

| | | | | | | | | | | Make the memrotate functions a function pointer table so that we can replace it with optimized versions, and implement an optimized NEON version for the 90 and 270 rotations.

* Included ARM NEON optimizations from pixman in Qt.Samuel Rødal2010-03-261-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
