close()

void DummyPresentation::close ( ViewInterface::WeakPtr  vi )

inlineoverridevirtual

Gets called just before the View is destroyed

Precondition

Should be called from within a Gdk critical section (i.e. between gdk_threads_enter() and gdk_threads_leave() calls)

Implements Viewable.

{ return context; }

getPixelAverages()

PipetteLayerOperations::PipetteColor DummyPresentation::getPixelAverages ( Scroom::Utils::Rectangle< double >  area )

inlineoverridevirtual

Returns the average pixel values for each component, contained in the area.

Parameters

area	selected area to get the pixel values from.

Implements PipetteViewInterface.

  {
    return {{"C", 1.0}};

getProperty()

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

inlineoverridevirtual

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

Implements PresentationInterface.

{ return false; }

getRect()

Scroom::Utils::Rectangle< double > DummyPresentation::getRect ( )

inlineoverridevirtual

Return the dimensions of your presentation

Implements PresentationInterface.

{ return {0, 0, 100, 100}; }

getTitle()

std::string DummyPresentation::getTitle ( )

inlineoverridevirtual

Return the title of the presentation

Implements PresentationInterface.

{ return {}; }

isPropertyDefined()

bool DummyPresentation::isPropertyDefined ( const std::string &  name )

Implements PresentationInterface.

{ return PIPETTE_PROPERTY_NAME == name; }

open()

void DummyPresentation::open ( ViewInterface::WeakPtr  vi )

inlineoverridevirtual

Gets called just after the View is created

Precondition

Implements Viewable.

{};

redraw()

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

inlineoverridevirtual

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.

Implements PresentationInterface.
