Detailed Description

Represent some 2D content

Anything that should be shown by Scroom in a window should implement this interface.

Objects implementing this interface are typically returned by NewPresentationInterface::createNew() and OpenPresentationInterface::open().

Member Typedef Documentation

Ptr

using PresentationInterface::Ptr = boost::shared_ptr<PresentationInterface>

WeakPtr

using PresentationInterface::WeakPtr = boost::weak_ptr<PresentationInterface>

Member Function Documentation

getAspectRatio()

virtual Scroom::Utils::Point<double> PresentationInterface::getAspectRatio ( ) const

inlinevirtual

Reimplemented in TransformPresentation.

{ return Scroom::Utils::make_point(1.0, 1.0); }

Here is the call graph for this function:

getProperty()

virtual bool PresentationInterface::getProperty ( const std::string &  name, std::string &  value  )

pure virtual

Return the value of the requested property

Parameters

[in]	name	The name of the requested property
[out]	value	The value of the requested property

Return values

true	if the property existed
false	if the property didn't exist

Implemented in anonymous_namespace{tiledbitmappresentation.cc}::TiledBitmapPresentation, TransformPresentation, TransparentOverlayPresentation, ExamplePresentation, anonymous_namespace{determine-size-test.cc}::PresentationInterfaceStub, and DummyPresentation.

getRect()

virtual Scroom::Utils::Rectangle<double> PresentationInterface::getRect ( )

pure virtual

Return the dimensions of your presentation

Implemented in TransformPresentation, anonymous_namespace{tiledbitmappresentation.cc}::TiledBitmapPresentation, anonymous_namespace{determine-size-test.cc}::PresentationInterfaceStub, TransparentOverlayPresentation, ExamplePresentation, and DummyPresentation.

getTitle()

virtual std::string PresentationInterface::getTitle ( )

pure virtual

Return the title of the presentation

Implemented in TransformPresentation, anonymous_namespace{tiledbitmappresentation.cc}::TiledBitmapPresentation, anonymous_namespace{determine-size-test.cc}::PresentationInterfaceStub, TransparentOverlayPresentation, ExamplePresentation, and DummyPresentation.

isPropertyDefined()

virtual bool PresentationInterface::isPropertyDefined ( const std::string &  name )

pure virtual

Return true if the named property exists

Implemented in anonymous_namespace{tiledbitmappresentation.cc}::TiledBitmapPresentation, TransformPresentation, TransparentOverlayPresentation, ExamplePresentation, DummyPresentation, and anonymous_namespace{determine-size-test.cc}::PresentationInterfaceStub.

redraw()

virtual void PresentationInterface::redraw ( ViewInterface::Ptr const &  vi, cairo_t *  cr, Scroom::Utils::Rectangle< double >  presentationArea, int  zoom  )

pure virtual

Draw the requested ara at the requested zoom level

Parameters

vi	The ViewInterface on whose behalf the request is made
cr	The context to draw the area on
presentationArea	the area that is to be drawn. The given x and y coordinates should map on 0,0 of the given context cr.
zoom	The requested zoom level. One pixel of your presentation should have size 2**zoom when drawn. zoom may be negative.

Implemented in TransformPresentation, TransparentOverlayPresentation, ExamplePresentation, anonymous_namespace{determine-size-test.cc}::PresentationInterfaceStub, DummyPresentation, and anonymous_namespace{tiledbitmappresentation.cc}::TiledBitmapPresentation.
