Detailed Description

Modifier drawing an image.

Constructor & Destructor Documentation

ImageModifier()

stmg::ImageModifier::ImageModifier ( Init &&  oInit )

explicitnoexcept

Constructor.

Parameters

oInit

The initialization data.

Member Function Documentation

drawTile()

FLOW_CONTROL stmg::ImageModifier::drawTile ( const Cairo::RefPtr< Cairo::Context > &  refCc, StdThemeDrawingContext &  oDc, const Tile &  oTile, int32_t  nPlayer, const std::vector< double > &  aAniElapsed  )

overridevirtualnoexcept

Draw tile (with player skin).

Parameters

refCc	The cairo context. Cannot be null.
oDc	The theme drawing context. Cannot be null.
oTile	The tile to draw.
nPlayer	The player the tile "belongs" to. -1 means no player. Must be >= -1.
aAniElapsed	The tile animations current value.

Returns

Whether the caller should continue or stop painting.

Implements stmg::StdThemeModifier.

registerTileSize()

void stmg::ImageModifier::registerTileSize ( int32_t  nW, int32_t  nH  )

overrideprotectedvirtualnoexcept

Register tile size.

Make sure to unregisterTileSize() when done with this size.

This method should be implemented to cache images for frequently used sizes.

Subclasses of ContainerModifier should not propagate this to contained Modifier instances since StdTheme does it automatically.

Parameters

nW	The tile width. Must be positive.
nH	The tile height. Must be positive.

Reimplemented from stmg::StdThemeModifier.

unregisterTileSize()

void stmg::ImageModifier::unregisterTileSize ( int32_t  nW, int32_t  nH  )

overrideprotectedvirtualnoexcept

Unregister tile size.

Called when a tile size no longer needed. See registerTileSize().

Parameters

nW	The tile width. Must be positive.
nH	The tile height. Must be positive.

Reimplemented from stmg::StdThemeModifier.
