3b748a44c6bd2ea05fe16839caf73dbe50bd7ae9 18-Apr-2013 Romain Guy <romainguy@google.com> Pack preloaded framework assets in a texture atlas

When the Android runtime starts, the system preloads a series of assets
in the Zygote process. These assets are shared across all processes.
Unfortunately, each one of these assets is later uploaded in its own
OpenGL texture, once per process. This wastes memory and generates
unnecessary OpenGL state changes.

This CL introduces an asset server that provides an atlas to all processes.

Note: bitmaps used by skia shaders are *not* sampled from the atlas.
It's an uncommon use case and would require extra texture transforms
in the GL shaders.

WHAT IS THE ASSETS ATLAS

The "assets atlas" is a single, shareable graphic buffer that contains
all the system's preloaded bitmap drawables (this includes 9-patches.)
The atlas is made of two distinct objects: the graphic buffer that
contains the actual pixels and the map which indicates where each
preloaded bitmap can be found in the atlas (essentially a pair of
x and y coordinates.)

HOW IS THE ASSETS ATLAS GENERATED

Because we need to support a wide variety of devices and because it
is easy to change the list of preloaded drawables, the atlas is
generated at runtime, during the startup phase of the system process.

There are several steps that lead to the atlas generation:

1. If the device is booting for the first time, or if the device was
updated, we need to find the best atlas configuration. To do so,
the atlas service tries a number of width, height and algorithm
variations that allows us to pack as many assets as possible while
using as little memory as possible. Once a best configuration is found,
it gets written to disk in /data/system/framework_atlas

2. Given a best configuration (algorithm variant, dimensions and
number of bitmaps that can be packed in the atlas), the atlas service
packs all the preloaded bitmaps into a single graphic buffer object.

3. The packing is done using Skia in a temporary native bitmap. The
Skia bitmap is then copied into the graphic buffer using OpenGL ES
to benefit from texture swizzling.

HOW PROCESSES USE THE ATLAS

Whenever a process' hardware renderer initializes its EGL context,
it queries the atlas service for the graphic buffer and the map.

It is important to remember that both the context and the map will
be valid for the lifetime of the hardware renderer (if the system
process goes down, all apps get killed as well.)

Every time the hardware renderer needs to render a bitmap, it first
checks whether the bitmap can be found in the assets atlas. When
the bitmap is part of the atlas, texture coordinates are remapped
appropriately before rendering.

5dc7fa709646799a5207a5d217f70aa02bf4a3aa 12-Mar-2013 Romain Guy <romainguy@google.com> Add TaskManager API

This API can be used to run arbitrary tasks on a pool of worker
threads. The number of threads is calculated based on the number
of CPU cores available.

The API is made of 3 classes:

TaskManager
Creates and manages the worker threads.

Task
Describes the work to be done and the type of the output.
A task contains a future used to wait for the worker thread
to be done computing the result of the task.

TaskProcessor
The processor dispatches tasks to the TaskManager and is
responsible for performing the computation required by
each task. A processor will only be asked to process tasks
sent to the manager through the processor.

A typical use case:

class MyTask: Task<MyType>

class MyProcessor: TaskProcessor<MyType>

TaskManager m = new TaskManager();
MyProcessor p = new MyProcessor(m);
MyTask t = new MyTask();
p.add(t);

// Waits until the result is available
MyType result = t->getResult();

3D rotations can undo scale/skew transforms; since FreeType only accepts
2x2 matrices we can end up generating very large glyphs that are drawn
at a 1:1 scale on screen. For instance, if the current transform has a
scale of 2000 set on both X and Y axis and a perspective Z factor set to
Z, the actual scale factor on screen ends up being 1. We would however
generate glyphs with a scale factor of 2000 causing the font renderer
to blow up.

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.

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.

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.

a stencil buffer to be always present. In addition, extra wiring is
required in JNI and display lists.

This change only adds the necessary JNI/C++ APIs and some extra
plumbing to start the real work on properly supporting region
clipping.

A new debug define called DEBUG_CLIP_REGIONS can be used to draw
the current clip region. It is off by default, as is region
clipping.

The default implementation of clipPath() and clipRegion(), now
in native, mimics the previous Dalvik implementation to prevent
regressions.

e816baea651476aca4407200d4a5e629b9ab8dfa 09-Aug-2012 Chet Haase <chet@google.com> Optimize interactions with glyph cache

There are two fixes here:
- precaching: instead of caching-then-drawing whenever there is a new
glyph, we cache at DisplayList record time. Then when we finally draw that
DisplayList, we just upload the affected texture(s) once, instead of once
per change. This is a huge savings in upload time, especially when there are
larger glyphs being used by the app.
- packing: Previously, glyphs would line up horizontally on each cache line, leaving
potentially tons of space vertically, especially when smaller glyphs got put into cache
lines intended for large glyphs (which can happen when an app uses lots of unique
glyphs, a common case with, for example, chinese/japanese/korean languages). The new
approach packs glyphs vertically as well as horizontally to use the space more efficiently
and provide space for more glyphs in these situations.

An optimization for paths is to only create a texture for the original native
Path object, and have all copies of that object use that texture. This works in
most cases, but sometimes that original path object may get destroyed (when the
SDK path object is finalized) while we are still referencing and using that object
in the DisplayList code. This causes undefined errors such as crashes and hanging
as we iterate through the operations of a destroyed (and garbage-filled) path object.

The fix is to use the existing ResourceCache to refcount the original path until
we are done with it.

So even though the child view was all set to recreate its display list
according to the property change, the layer in the tree above it would stay

Some views (such as ImageView and TextView) handle non-opaque alpha
values directly. This was originally an optimization, but we can handle it faster
in many cases without this optimization when DisplayList properties are enabled.
Basically, if a view has non-overlapping rendering, we set the alpha value directly
on the renderer (the equivalent of setting it on the Paint object) and draw each
primitive with that alpha value. Doing it this way avoids re-creating DisplayLists
while getting the same speedup that onSetAlpha() used to get pre-DisplayList properties.

errors due to the way that some transforms were being handled (specifically,
those coming from the old Animations and ViewGroup's childStaticTransformation
field). This change pushes *all* transform/alpha data from View.draw() into
the view's DisplayList, making DisplayLists more encapsulated (and correct).

When a drawPath command is recorded in a display list, a copy of the
source path is made to preserve against possible modifications of the
said source path. Copies are discarded when a display list is cleared,
which usually happens on invalidate(). This means that even if a path
is never modified, the texture generated to draw it on screen is
destroyed every time an invalidate() is issued. This change fixes this
problem by introducing a reference to the source path in the copy.
If both the copy and the source path have the same genID, they are
the same path and can share the same texture.

of showing the drop down popup. ACTV was unfortunately not ready to show

ACTV in a weird state that in turn caused a window to be leaked and really
bad behavior to occur in the lower graphics levels.

This could cause the draw() code of views to be invoked too often
or worse, called with the wrong canvas. For instance, a view backed
by a software layer could get its draw() method called to record a
display list. Using a software layer is the recommended way to use
drawing operations not supported in hardware. Since we would
sometimes call the draw() method with the hardware backend anyway,
the app could crash by executing an unsupported operation.

aa6c24c21c727a196451332448d4e3b11a80be69 29-Apr-2011 Romain Guy <romainguy@google.com> New widget: TextureView
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.

All accelerated lines are now rendered as quads. Hairlines used to
be rendered as GL_LINES, but these lines don't render the same as our

a bug in the way that we were offsetting quads (and not offseting points)
to ensure that our lines/points actuall start on the same pixels as
Skia's.

Bug #4092053

The problem always existed but was made visible by partial invalidation.
When saving a layer, the renderer would try to postpone glClear()
operations until the next drawing command. This however does not work
since the clip might have changed. The fix is rather simple and
simply gets rid of this "optimization" (that turned out to be
usless anyway given how View issues saveLayer() calls.)

This change also fixes an issue with gradients (color stops where
not properly computed when using a null stops array) and optimizes
display lists rendering (quickly rejects larger portions of the
tree to avoid executing unnecessary code.)

This change also fixes two bugs that prevented partial invalidates

redraw the entire screen.

d38e776a3cc8cb53945cbebafbe6f6c2e3501fa5 21-Dec-2010 Xavier Ducrohet <xav@android.com> LayoutLib: support for layers.

Layers require that drawing methods potentially
draw in more than one bitmaps.

To handle this this patch offers the following:
- move all drawing methods to use Drawable
- Drawables are now handled by GcSnapshot since
its the one handling the layers
- moved Canvas_Delegate.createCustomGraphics to
GcSnapshot which does not expose the Graphics2D
objects anymore so its draw() methods are the only
way to draw.
- handles creating layers in GcSnapshot.save() and
blitting them in restore()

Other changes:
- Clean up the create/save API in GcSnapshot
- Fixed drawing bitmaps with alpha and other
composite modes.

63fd87113cea6abec97a6cd966e090e9b590fc3b 21-Dec-2010 Xavier Ducrohet <xav@android.com> LayoutLib: Misc rendering fixes.

- always set up the stroke. Paint may not have the proper
style when drawing lines. stroke should still be setup.

- Fixed vertical linear gradient. Old code generated
a gradient ratio of NaN

- Fixed alpha rendering when using shaders. In that
case the alpha channel from the paint color should be
used in conjunction with the shader.

- Fixed miter limit. Java expects the value to be multiplied
by the stroke width

- Fixed support for drawing ALPHA_8 bitmaps. Java2D doesn't
have bitmaps with only alpha channels, so we keep using
ARGB bitmaps but when drawing them into a bitmap we erase
the color information.

d348b6eaa98e23cb38d90906df109aaa2d20ea7f 20-Dec-2010 Xavier Ducrohet <xav@android.com> LayoutLib: support for Path and BitmapShader using delegates.

Also created delegates for all missing shader, xfermode
and patheffect classes. Moved the logic of the xfermode,
and patheffects that was in Canvas_Delegate into the
xfermode/patheffect classes, and added support (in all
3 clases) for knowing if the shader/xfermode/patheffect
is actually supported or not. Make use of fidelityWarning
in LayoutLog if they are not.
