* remove SkRefCnt safeRef() and safeUnref(), and replace the call-sites withGravatar reed@google.com2011-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkSafeRef() and SkSafeUnref(). This is basically a bug waiting to happen. An optimizing compiler can remove checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on precisely this check... void SkRefCnt::safeRef() { if (this) { this->ref(); } } Since a compiler might skip the if-clause, it breaks the intention of this method, hence its removal. static inline void SkSafeRef(SkRefCnt* obj) { if (obj) { obj->ref(); } } This form is not ignored by an optimizing compile, so we use it instead. git-svn-id: http://skia.googlecode.com/svn/trunk@762 2bbb7eff-a529-9590-31e7-b0007b416f81

It was very exploratory for me to make this work. - Add an interface to SkFontHost to retrieve font information and provide NULL implementations on all platforms except Linux. - Segment large Type 1 fonts into fonts with shared resources with 255 glyphs each. - Convert the various Type 1 formats to the form PDF wants. - Update font as we draw text instead of as part of the graphical state. - Remove built-in font support, we can't really use it. Other changes I can pull out to a separate CL if you like. - Add SkTScopedPtr class. - Fix double free of resources. - Fix bug in resource unique-ifying code. - Don't print anything for any empty clip path. - Fix copy paste error - MiterLimit. - Fix sign extension bug in SkPDFString - Fix FlateTest rename that was missed on a previous commit.

* Fix perf regression in Color32.Gravatar senorblanco@chromium.org2010-12-16
| | | | | | | | | | | | | | | | The regression was due to the fact that we were calling PlatformColorProc() for every span (which in turns makes CPUID, a fairly expensive call). Since we draw a lot of rects, and rects have 1-pixel wide spans for the vertical segments, that's a lot of CPUID. Fixed by cacheing the result of PlatformColorProc(), as is done for the other platform-specific blitters.

* SSE2 optimizations for 32bit Color operation.Gravatar senorblanco@chromium.org2010-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | [Patch from weiwei.li@intel.com] SSE2 optimization has been added by Stephen White before, this improves the skia performance on SSE2-supporting platform. (please refer to below issues) Issue 171055: More SSE2ification Issue 157141: More SSE2ification Issue 150060: minor tweaks to SSE2 code for -fPIC Issue 144072: SSE2 optimizations for 32bit blending blitters This CL implements SSE2 optimizations for the 32bit Color operation. Like above issues, it uses CPUID to detect for SSE2 and changes the platform procs at runtime as well. The 32bit Color operation is heavily used on Chrome HTML5 canvas operations. Take Microsoft IE test drives Pulsating Bubbles as example (http://ie.microsoft.com/testdrive/Performance/PulsatingBubbles/Default.xhtml), if running this cases on Chrome, the overhead of 32bit Color operation is about 40~50%. So this CL will make skia performance more better, and also make Chrome HTML5 canvas performance more better. Additional, this CL has passed the skia bench & tests validation, the result is pretty good. We also apply this CL to the latest chromium, and re-run Microsoft IE test drives Pulsating Bubbles, the performance is improved by almost 9~10%. git-svn-id: http://skia.googlecode.com/svn/trunk@633 2bbb7eff-a529-9590-31e7-b0007b416f81

* Add safe size/copy functions to Skia.Gravatar wjmaclean@chromium.org2010-11-16
| | | | | | | | | | | | | | | | | | | | | | This patch adds four methods to SkBitmap. There are two functions to return "safe size", defined as the number of pixels from the value returned by getPixels() to the end of the allocated buffer. There is one version of fillPixels() to copy the bitmap instance into an external buffer (with specified size, and using specified stride), and another fillPixels() to copy from an external buffer to the instance bitmap. In the latter case the specified height, width and pixel format must match that used by the bitmap instance, although the specified stride may be any value at least as large as the minimum stride for the specified geometry. It is assumed that the external buffer is of size at least (height - 1)*stride + width * bytesPerPixel. Both fillPixels() functions return false if the copy is not possible with the specified parameters.

* Remove include of SkGLDevice.h from SkGLCanvas.hGravatar vandebo@chromium.org2010-11-11
| | | | | | | | | | | | | | | | The '#include "SkGLDevice.h"' from include/core/SkDevice.h requires internal Skia code to be added to the include search paths when using the deprecated API. This change adds back SkGLCanvas.cpp to avoid exposing SkGLDevice.h to the public API. The change also includes an explicit virtual destructor on SkDeviceFactory to silence a -Wnon-virtual-dtor warning and allow for -Werror.
