* Support RGBA fonts and bitmap fonts (and RGBA bitmap fonts)Victoria Lease2013-07-311-81/+216
| | | | | | | | | | | | | | | | | | | | | | | | | | | Quite a few things going on in this commit: - Enable bitmap strikes by default in Paint objects. The SkPaint parameter that enables bitmap strikes was not previously included in DEFAULT_PAINT_FLAGS. This effectively disabled bitmap fonts. Oops! It's for the best, though, as additional work was needed in Skia to make bitmap fonts work anyway. - Complain if TEXTURE_BORDER_SIZE is not 1. Our glyph cache code does not currently handle any value other than 1 here, including zero. I've added a little C preprocessor check to prevent future engineers (including especially future-me) from thinking that they can change this value without updating the related code. - Add GL_RGBA support to hwui's FontRenderer and friends This also happened to involve some refactoring for convenience and cleanliness.

|\ | | | | | | | | * commit '55b883b0a960b37aa453253f3ccb614dd95c221c': Draw Operation merging
| * Draw Operation mergingChris Craik2013-04-151-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge simple bitmap draw operations and text operations to avoid issuing individual gl draws for each operation. Merging other ops to be done eventually. The methods are different - the bitmap merging generates a single mesh for reused, unclipped images (esp. repeated images in a listview) The text approach queries just defers the normal font rendering until the last drawText in the sequence that can share the same shader. Patches are sorted and merged, but don't yet have a multiDraw implementation. For now, the pretending-to-merge gives better sorting behavior by keeping similar patches together.

| * Introduce PixelBuffer API to enable PBOsRomain Guy2013-04-111-51/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform asynchronous texture uploads to free up the CPU. This change does not enable the use of PBOs unless a specific property is set (Adreno drivers have issues with PBOs at the moment, Mali drivers work just fine.) This change also cleans up Font/FontRenderer a little bit and improves performance of drop shadows generations by using memcpy() instead of a manual byte-by-byte copy. On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance behaves like a simple byte array. The extra APIs introduced for PBOs (map/unmap and bind/unbind) are pretty much no-ops for CPU pixel buffers and won't introduce any significant overhead. This change also fixes a bug with text drop shadows: if the drop shadow is larger than the max texture size, the renderer would leave the GL context in a bad state and generate 0x501 errors. This change simply skips drop shadows if they are too large. Change-Id: I2700aadb0c6093431dc5dee3d587d689190c4e23

|\ \ | |/ | | | | | | | | | | into jb-mr2-dev * commit '21af446ce9704bdc465bf15755148c5de50ea019': First OpenGL ES 3.0 based optimization
| * First OpenGL ES 3.0 based optimizationRomain Guy2013-04-041-4/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* | Phase 1 of refactoring SystemServer.Dan Morrill2013-04-041-29/+39
|/ | | | | | | | | | SystemServer is currently a monolithic class that brings up key system services. This change is the first phase of refactoring it to be more configurable. Specifically, it adds a set of on/off switches used to control startup of individual services. Future plans include finer grained controls and a more explicit and consistent startup sequence for these services. Change-Id: I7299f5ce7d7b74a34eb56dffb788366fbc058532
* Optimize text GL setupRomain Guy2013-03-201-4/+8
| | | | | | | | Only performs the GL setup steps when at least one glyph is drawn. This change also skips various draw operations when the specified paint draws with alpha = 0. Change-Id: I9eda148b0503acffc552ee19196f5d52e958a1a2
* Reduce number of glDraw calls when drawing textRomain Guy2013-03-191-80/+41
| | | | | | | | This change moves the mesh buffer from FontRenderer to CacheTexture to help reduce the number of texture binds and glDraw calls when drawing text that spans across multiple textures. Change-Id: I7de574d88313ca3672879ca878c253ff5f131fc1
* Minimize texture binds when drawing textRomain Guy2013-03-191-14/+15
| | | | | | | | | | | When several CacheTextures are used to draw text, sort the draw batches by texture ID to minimize state changes in the driver. This change also tweaks the font cache size and renames a property that was too long to be set using setprop. Change-Id: I0a36dfffe58c9e75dd7384592d3343c192d042b1

* Support 3D rotations when drawing textRomain Guy2013-02-281-0/+10
| | | | | | | | | | | | | If a perspective transform is set on the Canvas, drawText() should not attempt to rasterize glyphs in screen space. This change uses the old behavior instead (i.e. rasterize the glyphs at the native font size and apply the transform on the resulting mesh.) This change also adds an optimization: empty glyphs (spaces) do not generate vertices anymore. This saves a lot of vertices in text heavy applications such as Gmail.

* Another optimization of glyph cache uploadsSangkyu Lee2012-11-281-18/+31
| | | | | | | | | | | | Previously, cache textures were updated whenever mCurrentCacheTexuture was changed. Since updating cache textures needs glTexSubImage2D call, frequent changing of mCurrentCacheTexture (which can easily happen when an app uses lots of unique glyphs even with precaching) caused many glTexSubImage2D calls and bad framerates. This patch optimized isssueDrawCommand function. Consequently, changing mCurrentCacheTexture doesn't cause glTexSubImage2D call any more and it will improve font rendering performance.

* Optimize glyph cache texture uploadsChet Haase2012-09-231-7/+10
| | | | | | | | | | | | Only upload the changed area of the glyph cache, not the entire bitmap. Note that we can't do the full-on optimization here of copying a sub-rect of the bitmap because of GL ES 2 limitations, but we can at least copy the horizontal stripe containing the dirty rect, which can still be a big savings over uploading the entire bitmap.
