2018-12-03Remove ; from closing namespaces in libs/hwuiChris Blume
When closing a namespace a } is sufficient. It doesn't need to be }; like closing a class or enum. Within frameworks/base/libs/hwui there is a mix between } and }; when closing a namespace. There are even mixes between a .h and the corresponding .cpp files. In a separate CL I was asked to not close with };. That was a good comment. I adopted the style from nearby code. This CL cleans up the nearby code. Test: I made sure the code still built as expected. Change-Id: Ieb314a4f48d6e33752463f3be4361fdc9be97482

2013-12-123d view system!Chris Craik
True 3d transformations are now supported by DisplayLists and the renderer, initially with the translationZ property on view. Renderer operations used directly by DisplayList (formerly, clip/save/restore/saveLayer) are now more simply managed by allocating them temporarily on the handler's allocator, which exists for a single frame. This is much simpler than continuing to expand the pool of pre-allocated DisplayListOps now that more operations are called directly by DisplayList, especially with z ordered drawing. Still TODO: -APIs for camera positioning, shadows -Make Z apis public, and expose through XML -Make invalidation / input 3d aware Change-Id: I95fe6fa03f9b6ddd34a7e0c6ec8dd9fe47c6c6eb
2013-09-20Correct bitmap merging logicChris Craik
bug:10863163 This fixes two issues The check for pure translation was incorrect. It was fixed and renamed for clarity. Certain matrix paths weren't setting kTypePositiveScale. For simplicity (and because positive scale is simple to check) removed flag in favor of dynamic checking. Change-Id: Ic5ce235653ef49a68b8b242bd89fc2e95874ecc9

2013-03-05Take only the scale params into account to rasterize textRomain Guy
This change extracts the scale parameters of the current transform to pass then to the font renderer. Rotation and perspective are applied to the generated mesh inside the vertex shader. This limits the number of glyphs we have to create in the font cache and thus reduces memory churn. Change-Id: Ic5b3bae2b2b0e0250a8ee723b071a1709725c749
2013-03-05Fix colored rects clipping and code cleanupRomain Guy
The drawColorRects() method was clipping individual rectangles using the wrong parameters left, top, right and bottom instead of l, r, t and b. It also checked for count == 0 after the loop when it should have checked for vertexCount == 0. The quickReject is now not part of the loop since it's a bit overkill to perform so many matrix multiplications. What we really care about is the final quickReject performed on the max bounds of the entire set of rectangles. This change also replaces all instances of mSnapshot->transform by currentTransform() to make the code slightly more readable. Change-Id: I6485280414499716852f7dbfba186774eb6763d4
2013-02-27Properly scale textRomain Guy
This change does not apply to drawPosText() and drawTextOnPath() yet. Prior to this change, glyphs were always rasterized based on the font size specified in the paint. All transforms were then applied on the resulting texture. This creates rather ugly results when text is scaled and/or rotated. With this change, the font renderer will apply the current transform matrix to the glyph before they are rasterized. This generates much better looking results.

2013-01-17Implement clipRect with a transform, clipRegion & clipPathRomain Guy
Bug #7146141 When non-rectangular clipping occurs in a layer the render buffer used as the stencil buffer is not cached. If this happens on a View's hardware layer the render buffer will live for as long as the layer is bound to the view. When a stencil buffer is required because of a call to Canvas.saveLayer() it will be allocated on every frame. A future change will address this problem. If "show GPU overdraw" is enabled, non-rectangular clips are not supported anymore and we fall back to rectangular clips instead. This is a limitation imposed by OpenGL ES that cannot be worked around at this time. This change also improves the Matrix4 implementation to easily detect when a rect remains a rect after transform.

2012-05-07Fix issue where scale-animating text would jump temporarily a few pixelsChet Haase
Some logic in the native matrix code would determine that a matrix was 'pureTranslate' based on the scale values of a matrix being close-enough to 1, which was within a very small epsilon. This works in general, because screen space coordinates make that epsilon value irrelevant, so close-enough really is close-enough. However, TextView, when centering text, works in a coordinate system that is quite huge, with left/right values about 500,000. These numbers multiplied times that small epsilon value would give a result that was significant, and would cause a miscalculation of up to 4-5 pixels, causing the snap that we'd see for a couple of frames as the scale got "close enough" to 1. The fix is to remove the optimization of "close enough". What we really need the matrix to do is to identify itself as being translate-only when no scale as been set (which is the default). For the purposes of that check, it is good enough to simply check the values against 1 directly. Similarly, the bounds-check logic needs to check against 0 and 1 directly.

2010-06-27Reduced the complexity of layers composition.Romain Guy
This change also refactors the code base a bit by moving classes out of OpenGLRenderer into separate headers/implementations. This makes the code more manageable. This change also adds documentation for implementation methods. The undocumented methods are simply Skia's Canvas methods. Change-Id: I54c68b443580a0129251dddc1a7ac95813d5289e
2010-06-26Add implementations for saveLayerAlpha() and textured rects.Romain Guy
Even though there's an implementation for textured rects, drawBitmap() is not hooked up yet as it will require a good texture cache. This method is implemented using FBOs. There's currently an issue either in the driver or in the Canvas renderer that forces the FBO to be fullscreen, which is extremely expensive and yields terrible performance.

2010-06-24Add colored rectangles implementation in OpenGLRenderer.Romain Guy
Drawing two rectangles one after the other discards the second one because of Z buffering issues. This will be fixed in another changelist. Change-Id: Ida1b3cde8a78e60cacc07e477abc44def527ff67
2010-06-23Add support for transformations.Romain Guy
This change adds partial support for the following transforms: - scale() - translate() - rotate() - setMatrix() - getMatrix() The transform is stored in a snapshot and saved/restored as needed. The transform is currently not applied to the clip rect and is not mapped to the vertex shader. Change-Id: Id48993453311200804149917d0c126a4d0471226
2010-06-23Add implementations for clipRect(), save() and restore().Romain Guy
