* Fix TextureView texture filtering.Chris Craik2014-02-251-0/+14
| | | | | | | | | | | | | bug:11748993 TextureView should always be drawn with linear filtering if drawing a buffer sized differently from the layer. This fixes a bug where TextureViews that were sized differently from their contents wouldn't be drawn with texture filtering, causing visible scaling artifacts.

* Use global indices array to draw layersRomain Guy2013-07-221-1/+0
| | | | | | | | | | | | An array of indices local to a layer would only be necessary if we changed the way we resolve T-junctions. Since we only ever draw quads, let's just use the indices we use everywhere else. This change also uses the global indices array to render list of colored rectangles to save on the number of vertices generated CPU-side. Change-Id: Ia6d1970b0e9247805af5a114ca2a84b5d0b7c282

* Make layer double drawing visible in overdraw debug modeChris Craik2013-04-161-0/+1
| | | | | | | | | | | | | | | | | | A clipped saveLayer will cause two draws - first to an onscreen buffer, then again back to the framebuffer. This change - when in overdraw debug - reissues draws associated with a clipped saveLayer, but only to the stencil buffer. Operations within a saveLayer are shown correctly to be twice drawn, and View.setAlpha() without an associated hardware layer, or hasOverlappingRendering() are made more visible. Hardware layers, on any frame that they are updated, similarly draw twice, and will also be counted against the stencil buffer doubly. Note: greater depths of layers - e.g. a saveLayer within a saveLayer - are not respected, as that would require additional region tracking. Change-Id: I61fb0e61038fe66013d59914c20bb47a550dea7d
* First OpenGL ES 3.0 based optimizationRomain Guy2013-04-041-3/+4
| | | | | | | | | | | | | | | This change uses a new OpenGL ES 3.0 feature to upload less data when the font cache needs to be update. This can result in significant performance improvements on device with large textures or with locales that use a lot of glyphs (CJK for instance.) This change also fixes various unpack alignment issues. The unpack alignment, as well as the unpack row length, is not texture specific but a global state that affect all glTex/SubImage2D calls. Some of them were missing the appropriate glPixelStorei() call. This could result in corrupted textures. Change-Id: Iefb429d4d0d0b4e0faeadf27daafee6d30a21d85

| | | | | | | | | | Bug #8378964 This change defers drawing into layers until after the renderer for FBO0 is ready to draw. At that point, all the precaching is done which means all glyphs can be uploaded at once in the font caches. Change-Id: Ie1f7a7ff30f76f06fb3dbc72c7d05e66207d1ecb

| * Add a RenderBuffer object to store stencil buffers.Romain Guy2013-02-071-28/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug #7146141 This change is needed to add a render buffer cache to avoid creating and destroying stencil buffers on every frame. This change also allows the renderer to use a 1 bit or 4 bit stencil buffer whenever possible. Finally this change fixes a bug introduced by a previous CL which causes the stencil buffer to not be updated in certain conditions. The fix relies on a new optional parameter in drawColorRects() that can be used to avoid performing a quickReject on rectangles generated by the clip region.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Bug #7326824 When a layer is taken out of the cache and initialized it gets cleared to prepare it for future rendering. This triggers the following sequence of operations: glBindFramebuffer(layer.fbo) attach texture storage to FBO glClear() glBindFramebuffer(defaultFbo) The clear forces a resolve on tilers which stalls the CPU for a little while, thus producing jank during animations. This change moves the clear to the next frame when we know we will have to execute a resolve anyway. Change-Id: Ic1939c25df20ed65a4c48dc81ee549b2cd8b6ec3

* Fix occasional crash bug with layersChet Haase2012-09-171-15/+1
| | | | | | | | | | | | | | | | | | | | Launcher occasionally crashes with a stack trace indicating that the memory of a Layer object is corrupt. It is possible for us to delete a Layer structure and then, briefly, use it to draw a DisplayList again before that DisplayList gets recreated (without the layer that got deleted). When this happens, if the memory got corrupted, it's possible to crash. The fix is to add Layer to the other objects which we currently refcount (bitmaps, shaders, etc.). Then instead of deleting a Layer, we decrement the refcount. We increment when creating it, then increment it again when it's referenced from a DisplayList. Then we decrement the refcount instead of deleting it, and decrement when we clear a DisplayList that refers to it. Then when the refcount reaches 0, we delete it.

* Enable changing properties of layer paintChet Haase2012-09-071-7/+5
| | | | | | | | | | | | Previously, to draw a layered view with a changed Paint object for the drawLayer operation, you'd have to invalidate the parent view, to get the native DisplayList to pick up the new Paint properties. This change adds API and functionality so that the developer can call setLayerPaint(), which does the proper invalidation (lightweight, doesn't cause redrawing the view).

* New widget: TextureViewRomain Guy2011-04-281-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug #4343984 TextureView can be used to render media content (video, OpenGL, RenderScript) inside a View. The key difference with SurfaceView is that TextureView does not create a new Surface. This gives the ability to seamlessly transform, animate, fade, etc. a TextureView, which was hard if not impossible to do with a SurfaceView. A TextureView also interacts perfectly with ScrollView, ListView, etc. It allows application to embed media content in a much more flexible way than before. For instance, to render the camera preview at 50% opacity, all you need to do is the following: mTextureView.setAlpha(0.5f); Camera c = Camera.open(); c.setPreviewTexture(mTextureView.getSurfaceTexture()); c.startPreview(); TextureView uses a SurfaceTexture to get the job done. More APIs are required to make it easy to create OpenGL contexts for a TextureView. It can currently be done with a bit of JNI code. Change-Id: Iaa7953097ab5beb8437bcbbfa03b2df5b7f80cd7
