+# UNO-based Graphics Backend
+
+UNO-based graphics backend, lesser impedance to modern graphics APIs
+than vcl.
+
+## The canvas Framework
+
+The `canvas` framework is the successor of the system GUI and graphics
+backend VCL. Basic functionality is available, supplying just as much
+features as necessary to provide a VCL-equivalent feature set (except
+proper BiDi/CTL support).
+
+The `canvas` framework consists of the following two modules, `canvas` and
+`cppcanvas`. Additionally, a new generic graphics tooling is used (but
+not exclusively by the canvas, Armin's drawinglayer module also make
+use of it), which resides in `basegfx`.
+
+The UNO API used by the canvas is primarily under
+`css::rendering`, with `css::rendering::XCanvas`
+being the central interface.
+
+## The slideshow Engine
+
+The `slideshow` engine has replaced the former Impress-embedded
+presentation framework with a fully independent UNO component, and it
+is based on the canvas. Some features used there are only available
+from `canvas`, like double-buffering, and hardware-accelerated
+alpha-blending (currently not on all platforms).
+
+## Cairo canvas
+
+Cairo `canvas` is one of backends of canvas component. `canvas` is mostly
+used for slideshow rendering and also for emf+ rendering. we hoped it
+will even be used by drawing layer, but it didn't happen (yet?) for
+API look at `offapi/com/sun/star/rendering/`, the implementation is in
+`canvas` and `cppcanvas` modules.
+
+Cairo `canvas` backend uses Cairo library for rendering. Main advantage
+is support of alpha transparency and in some cases accelerated
+rendering.
+
+The backend itself is quite old and stable, not many changes in that
+area lately, mostly changes for emf+ rendering, communication with
+vcl and bugfixes
+
+## Future Works
+
+Look at Cairo `canvas` and situation when it is used
+(mostly slideshow).
+
+## TODO
+There still might be more cases when we
+can save some roundtrips when exchanging data with vcl.

+
+ Use this helper to handle the XCanvas part of your

+ and CanvasBase as a single template, but that would duplicate
+ a lot of code now residing in CanvasHelper only.
+
+ This template basically interposes itself between the full
+ interface you implement (i.e. not restricted to XCanvas. The
+ problem with UNO partial interface implementation actually is,
+ that you cannot do it the plain way, since deriving from a
+ common base subclass always introduces the whole set of pure
+ virtuals, that your baseclass helper just overridden) and your
+ implementation class. You then only have to implement the
+ functionality <em>besides</em> XCanvas.
+
+ <pre>
+ Example:
+ typedef ::cppu::WeakComponentImplHelper < css::rendering::XSpriteCanvas,
+ css::lang::XInitialization,
+ css::lang::XServiceInfo,
+ css::lang::XServiceName > CanvasBase_Base;
+ typedef ::canvas::internal::CanvasBase< CanvasBase_Base, CanvasHelper > ExampleCanvas_Base;
+
+ class ExampleCanvas : public ExampleCanvas_Base,
+ public SpriteSurface,
+ public RepaintTarget

+ Base( const Mutex& ) constructor (like the
+ WeakComponentImplHelper template has). As the very least,
+ the base class must be derived from uno::XInterface, as some
+ error reporting mechanisms rely on that.
+
+ @tpl CanvasHelper
+ Canvas helper implementation for the backend in question. This
+ object will be held as a member of this template class, and
+ basically gets forwarded all XCanvas API calls. Furthermore,
+ every time the canvas API semantically changes the content of
+ the canvas, CanvasHelper::modifying() will get called
+ (<em>before</em> the actual modification takes place).
+
+ @tpl Mutex
+ Lock strategy to use. Defaults to using the
+ BaseMutex-provided lock. Every time one of the methods is
+ entered, an object of type Mutex is created with m_aMutex as
+ the sole parameter, and destroyed again when the method scope
+ is left.
+
+ @tpl UnambiguousBase

+
+ @tpl CanvasHelper
+ Canvas helper implementation for the backend in question
+
+ @tpl Mutex
+ Lock strategy to use. Defaults to using the
+ BaseMutex-provided lock. Every time one of the methods is
+ entered, an object of type Mutex is created with m_aMutex as
+ the sole parameter, and destroyed again when the method scope
+ is left.
+
+ @tpl UnambiguousBase
+ Optional unambiguous base class for XInterface of Base. It's
+ sometimes necessary to specify this parameter, e.g. if Base
+ derives from multiple UNO interface (were each provides its
+ own version of XInterface, making the conversion ambiguous)
+
+ @see CanvasCustomSpriteHelper for further contractual
+ requirements towards the SpriteHelper type, and some examples.

+ /** Helper template base class for XGraphicDevice implementations.
+
+ This base class provides partial implementations of the
+ XGraphicDevice-related interface, such as XColorSpace.
+
+ This template basically interposes itself between the full
+ interface you implement (i.e. not restricted to XGraphicDevice
+ etc.). The problem with UNO partial interface implementation
+ actually is, that you cannot do it the plain way, since
+ deriving from a common base subclass always introduces the
+ whole set of pure virtuals, that your baseclass helper just
+ overridden) and your implementation class. You then only have
+ to implement the functionality <em>besides</em>
+ XGraphicDevice. If you want to support the optional debug
+ XUpdatable interface, also add that to the base classes
+ (client code will call the corresponding update() method,
+ whenever a burst of animations is over).
+
+ <pre>
+ Example:
+ typedef ::cppu::WeakComponentImplHelper < css::rendering::XGraphicDevice,
+ css::rendering::XColorSpace,
+ css::rendering::XPropertySet,
+ css::lang::XServiceInfo,
+ css::lang::XServiceName > GraphicDeviceBase_Base;
+ typedef ::canvas::internal::GraphicDeviceBase< GraphicDeviceBase, DeviceHelper > ExampleDevice_Base;
+
+ class ExampleDevice : public ExampleDevice_Base
+ {
+ };
+ </pre>
+
+ @tpl Base
+ Base class to use, most probably the
+ WeakComponentImplHelper template with the appropriate
+ interfaces. At least XGraphicDevice should be among them (why else
+ would you use this template, then?). Base class must have an
+ Base( const Mutex& ) constructor (like the
+ WeakComponentImplHelper template has). As the very least,
+ the base class must be derived from uno::XInterface, as some
+ error reporting mechanisms rely on that.
+
+ @tpl DeviceHelper
+ Device helper implementation for the backend in question. This
+ object will be held as a member of this template class, and
+ basically gets forwarded all XGraphicDevice API calls that
+ could not be handled generically.
+
+ @tpl Mutex
+ Lock strategy to use. Defaults to using the
+ DisambiguationHelper-provided lock. Every time one of the methods is
+ entered, an object of type Mutex is created with m_aMutex as
+ the sole parameter, and destroyed again when the method scope
+ is left.
+
+ @tpl UnambiguousBase
+ Optional unambiguous base class for XInterface of Base. It's
+ sometimes necessary to specify this parameter, e.g. if Base
+ derives from multiple UNO interface (were each provides its
+ own version of XInterface, making the conversion ambiguous)

+
+ Use this helper to handle the XIntegerBitmap part of your
+ implementation.
+
+ @tpl Base
+ Base class to use, most probably one of the
+ WeakComponentImplHelperN templates with the appropriate
+ interfaces. At least XSpriteCanvas and SpriteSurface should be
+ among them (why else would you use this template, then?). Base
+ class must have a Base( const Mutex& ) constructor (like the
+ WeakComponentImplHelperN templates have).
+
+ @tpl CanvasHelper
+ Canvas helper implementation for the backend in question
+
+ @tpl Mutex
+ Lock strategy to use. Defaults to using the
+ BaseMutex-provided lock. Every time one of the methods is
+ entered, an object of type Mutex is created with m_aMutex as
+ the sole parameter, and destroyed again when the method scope
+ is left.
+
+ @tpl UnambiguousBase
+ Optional unambiguous base class for XInterface of Base. It's
+ sometimes necessary to specify this parameter, e.g. if Base
+ derives from multiple UNO interface (were each provides its
+ own version of XInterface, making the conversion ambiguous)
+
+ @see CanvasBase for further contractual requirements towards
+ the CanvasHelper type, and some examples.

+How to write a canvas test:
+===========================
+
+The easiest (relatively speaking) way is to copy&paste from somewhere. Use existing tests
+as the base, or canvas/workben/canvasdemo.cxx should be a good source too. If that doesn't
+help, then you'll need to find the right UNO interfaces (see canvas/README). Have "fun".
+
+
+Currently only the vclcanvas implementation is tested, because it's the only one
+capable of working with offscreen surfaces. Other implementations would need to
+be fixed, and then added to the gb_CppunitTest_use_components list in the makefile.

+ /* Concepts:
+ =========
+
+ This OpenGL canvas implementation tries to keep all render
+ output as high-level as possible, i.e. geometry data and
+ externally-provided bitmaps. Therefore, calls at the
+ XCanvas-interfaces are not immediately transformed into colored
+ pixel inside some GL buffer, but are retained simply with their
+ call parameters. Only after XSpriteCanvas::updateScreen() has
+ been called, this all gets transferred to the OpenGL subsystem
+ and converted to a visible scene. The big advantage is, this
+ makes sprite modifications practically zero-overhead, and saves
+ a lot on texture memory (compared to the directx canvas, which
+ immediately dumps every render call into a texture).
+
+ The drawback, of course, is that complex images churn a lot of
+ GPU cycles on every re-rendering.
+
+ For the while, I'll be using immediate mode, i.e. transfer data
+ over and over again to the OpenGL subsystem. Alternatively,
+ there are display lists, which at least keep the data on the
+ server, or even better, vertex buffers, which copy geometry
+ data over en bloc.
+
+ Next todo: put polygon geometry into vertex buffer (LRU cache
+ necessary?) - or, rather, buffer objects! prune entries older
+ than one updateScreen() call)
