* Factory methods for heap-allocated SkImageFilter objects.Gravatar commit-bot@chromium.org2014-03-10
| | | | | | | | | | | | | | | | | | This is part of an effort to ensure that all SkPaint effects can only be allocated on the heap. This patch makes the constructors of SkImageFilter and its subclasses non-public and instead provides factory methods for creating these objects on the heap. We temporarily keep constructor of publicly visible classes public behind a flag.

* NEON fast path for box blurGravatar commit-bot@chromium.org2014-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calculate 8 channels in parallel by using 16-bits to store each channel. Due to the limitation of VQRDMULH, (int16 * int16 * 2 + 0x8000) >> 16, the fast path can only support kernelSize < 128. 8 significant bits are kept at least in each stage, the final error should less-equal than 1. Pre-fetching memory for X-direction read. In fact pre-fetching memory doesn't help much for Y direction read, since it is a waste to load a cache line for only read 8 bytes.(I left it there to keep the symmetry. pre-fetch is cheap :) ) bench data on Nexus 10 before: running bench [640 480] blur_image_filter_large_10.00_10.00 8888: cmsecs = 25081.48 running bench [640 480] blur_image_filter_small_10.00_10.00 8888: cmsecs = 25038.04 running bench [640 480] blur_image_filter_large_1.00_1.00 8888: cmsecs = 25209.04 running bench [640 480] blur_image_filter_small_1.00_1.00 8888: cmsecs = 24928.01 running bench [640 480] blur_image_filter_large_0.00_1.00 8888: cmsecs = 17160.98 running bench [640 480] blur_image_filter_large_0.00_10.00 8888: cmsecs = 17924.11 running bench [640 480] blur_image_filter_large_1.00_0.00 8888: cmsecs = 14609.19 running bench [640 480] blur_image_filter_large_10.00_0.00 8888: cmsecs = 14625.91 after: running bench [640 480] blur_image_filter_large_10.00_10.00 8888: cmsecs = 14848.42 running bench [640 480] blur_image_filter_small_10.00_10.00 8888: cmsecs = 16037.29 running bench [640 480] blur_image_filter_large_1.00_1.00 8888: cmsecs = 14819.55 running bench [640 480] blur_image_filter_small_1.00_1.00 8888: cmsecs = 14563.69 running bench [640 480] blur_image_filter_large_0.00_1.00 8888: cmsecs = 11905.34 running bench [640 480] blur_image_filter_large_0.00_10.00 8888: cmsecs = 11883.85 running bench [640 480] blur_image_filter_large_1.00_0.00 8888: cmsecs = 9576.51 running bench [640 480] blur_image_filter_large_10.00_0.00 8888: cmsecs = 9793.84 BUG= R=senorblanco@chromium.org, mtklein@google.com, reed@google.com, kevin.petit@arm.com, kevin.petit.arm@gmail.com Author: zheng.xu@arm.com Review URL: https://codereview.chromium.org/105893003 git-svn-id: http://skia.googlecode.com/svn/trunk@13036 2bbb7eff-a529-9590-31e7-b0007b416f81

* Clean up the use of AutoScratchTexture in the gaussian blur and morphologyGravatar senorblanco@chromium.org2012-07-18
| | | | | | | | | | | | | | | | | | filters. Instead of passing in AutoScratchTextures for temporaries, we allocate them inside the function and detach() after rendering. Since the functions now return a ref()'ed texture, we no longer ref() the result in filter_texture(). Also, the imageblur gm was passing a paint with an image filter both to saveLayer()/restore(), and to every text draw call. Back when only restore() was applying filters, this was fine, but since we're now applying filters on all draw calls, this means we're double-blurring in this GM. I've reverted the Mac baselines for the imageblur GM to their previous versions; hopefully this will be correct. git-svn-id: http://skia.googlecode.com/svn/trunk@4659 2bbb7eff-a529-9590-31e7-b0007b416f81

* Implement Gaussian blurs for images. The caller creates an anGravatar senorblanco@chromium.org2011-11-09
SkBlurImageFilter, sets it on an SkPaint, passes that paint to saveLayer(), draws the primitives which are to be blurred, then calls restore(), which applies the blur. The blurs have separate sizes in the horizontal and vertical direction. This feature is GPU-only for now. NB: Due to the clipping change, there are slight pixel differences on the blurs_gpu and shadows_gpu tests, so those will require rebaselining on all platforms, as will some of the WebKit layout tests (TBD).
