2016-10-11Linear blending, step 1Romain Guy
NOTE: Linear blending is currently disabled in this CL as the feature is still a work in progress Android currently performs all blending (any kind of linear math on colors really) on gamma-encoded colors. Since Android assumes that the default color space is sRGB, all bitmaps and colors are encoded with the sRGB Opto-Electronic Conversion Function (OECF, which can be approximated with a power function). Since the power curve is not linear, our linear math is incorrect. The result is that we generate colors that tend to be too dark; this affects blending but also anti-aliasing, gradients, blurs, etc. The solution is to convert gamma-encoded colors back to linear space before doing any math on them, using the sRGB Electo-Optical Conversion Function (EOCF). This is achieved in different ways in different parts of the pipeline: - Using hardware conversions when sampling from OpenGL textures or writing into OpenGL frame buffers - Using software conversion functions, to translate app-supplied colors to and from sRGB - Using Skia's color spaces Any type of processing on colors must roughly ollow these steps: [sRGB input]->EOCF->[linear data]->[processing]->OECF->[sRGB output] For the sRGB color space, the conversion functions are defined as follows: OECF(linear) := linear <= 0.0031308 ? linear * 12.92 : (pow(linear, 1/2.4) * 1.055) - 0.055 EOCF(srgb) := srgb <= 0.04045 ? srgb / 12.92 : pow((srgb + 0.055) / 1.055, 2.4) The EOCF is simply the reciprocal of the OECF. While it is highly recommended to use the exact sRGB conversion functions everywhere possible, it is sometimes useful or beneficial to rely on approximations: - pow(x,2.2) and pow(x,1/2.2) - x^2 and sqrt(x) The latter is particularly useful in fragment shaders (for instance to apply dithering in sRGB space), especially if the sqrt() can be replaced with an inversesqrt(). Here is a fairly exhaustive list of modifications implemented in this CL: - Set TARGET_ENABLE_LINEAR_BLENDING := false in BoardConfig.mk to disable linear blending. This is only for GLES 2.0 GPUs with no hardware sRGB support. This flag is currently assumed to be false (see note above) - sRGB writes are disabled when entering a functor (WebView). This will need to be fixed at some point - Skia bitmaps are created with the sRGB color space - Bitmaps using a 565 config are expanded to 888 - Linear blending is disabled when entering a functor - External textures are not properly sampled (see below) - Gradients are interpolated in linear space - Texture-based dithering was replaced with analytical dithering - Dithering is done in the quantization color space, which is why we must do EOCF(OECF(color)+dither) - Text is now gamma corrected differently depending on the luminance of the source pixel. The asumption is that a bright pixel will be blended on a dark background and the other way around. The source alpha is gamma corrected to thicken dark on bright and thin bright on dark to match the intended design of fonts. This also matches the behavior of popular design/drawing applications - Removed the asset atlas. It did not contain anything useful and could not be sampled in sRGB without a yet-to-be-defined GL extension - The last column of color matrices is converted to linear space because its value are added to linear colors Missing features: - Resource qualifier? - Regeneration of goldeng images for automated tests - Handle alpha8/grey8 properly - Disable sRGB write for layers with external textures Test: Manual testing while work in progress Bug: 29940137 Change-Id: I6a07b15ab49b554377cd33a36b6d9971a15e9a0b

2016-04-07Make stopped state a first-class thingJohn Reck
Bug: 27286867 WindowManager has committed to stopped state controlling the lifecycle of the Surface, so make that a first-class thing in HWUI as well. This makes it more resistent to things like a rogue updateSurface() happening while mStopped=true, leading to bad things down the line. Instead let the surface be changed/updated as often as desired, and just block any attempt to draw on that surface. Also removes some unnecessary makeCurrent()s, as EglManager ensures that we *always* have a valid GL context now (using a pbuffer surface if there is no window surface set) Change-Id: Iead78ddebc7997e8fdb0c9534836352f5e54b9bd

2016-02-05hwui: set buffer destroyed swap mode explicitlyChristian Poetzsch
Not using EGL_SWAP_BEHAVIOR_PRESERVED_BIT as config attribute for eglChooseConfig doesn't automatically mean the swap behavior is buffer destroyed. This is driver implementation specific and on some hw this can still be buffer preserved. Make sure it is buffer destroyed by explicitly setting it for every new surface when requested.

2016-02-02libhwui: handle eglSwapBuffers with EGL_BAD_NATIVE_WINDOW error caseZhang Dongsheng
If eglSwapBuffers is called but the under surface was destroyed, the EGL_BAD_NATIVE_WINDOW error may also be generated according to the EGL spec 1.4. This really shouldn't happen from the upper, but add the graceful handling of this case also.

2014-12-10Don't preload textures for AssetAtlasJohn Reck
Bug: 18317479 RenderNode::prepareSubTree calls prefetchAndMarkInUse on every bitmapResoruce in the DisplayList. However, this resulted in textures being uploaded for bitmaps that would be drawn from the AssetAtlas instead. To fix this we teach TextureCache about the AssetAtlas so that calls to TextureCache return the Texture from AssetAtlas if it exists. Thus usage of AssetAtlas is now purely to allow for further optimizations via draw merging instead of a requirement to get any benefit at all. Change-Id: I65282fa05bac46f4e93822b3467ffa0261ccf200
