Detailed Description

Interact with your TiledBitmap

Member Typedef Documentation

Ptr

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

Member Function Documentation

clearCaches()

virtual void TiledBitmapInterface::clearCaches ( ViewInterface::Ptr  vi )

pure virtual

Clear all bitmap caches related to the view.

You'd typically do this if the bitmap has somehow changed appearance, for example when switching to a new Colormap.

Parameters

vi	The ViewInterface for which to clear the caches

Implemented in TiledBitmap.

getBottomLayer()

virtual boost::shared_ptr<Layer> TiledBitmapInterface::getBottomLayer ( )

pure virtual

Retrieve the bottom layer of the TiledBitmap.

This allows you to fill the layer with data yourself, instead of relying on setSource()

See also

setSource()

Implemented in TiledBitmap.

redraw()

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

pure virtual

Redraw a portion of the bitmap.

This is typically called from PresentationInterface::redraw()

See also

PresentationInterface::redraw()

Implemented in TiledBitmap.

setSource()

virtual void TiledBitmapInterface::setSource ( SourcePresentation::Ptr  sp )

pure virtual

Provide bitmap data to the TiledBitmap

Bitmap data will be loaded and pre-scaled in a fashion that least loads cpu and memory.

Parameters

sp	source of the bitmap data

Implemented in TiledBitmap.
