Member Function Documentation

◆ cleanupCaches()

void Maria::GeoLayer::cleanupCaches ( bool  keepCurrentFrame)
virtual

This method is called at regular intervals to clean up cached data, such as OpenGL textures, graphics buffers etc. Only data that can be reproduced automatically should be cleaned up by this method.

Parameters
keepCurrentFrameKeep data that are necessary for the current frame (if applicable).

◆ needsRedraw()

bool Maria::GeoLayer::needsRedraw ( ) const
virtual

Check if a layer requires a redraw on next frame. This will typicall be due to changed content, newly loaded data, etc.

Returns

Reimplemented in Maria::DrawLayer, Maria::ElevationAnalysisLayer, Maria::GeoBitmapLayer, and Maria::MapLayer.

◆ update()

bool Maria::GeoLayer::update ( const std::shared_ptr< RasterProjector > &  viewport,
double  scale,
float  pixelScale 
)
virtual

Update layer for rendering. This method should determine if there is anything to render in the layer, and prepare the layer for rendering.

Parameters
viewport
scaleMap scale for the current view.
pixelScaleScale factor for the pixel allowed pixel size.
Returns
True if the layer should be rendered, false if not.

Reimplemented in Maria::GridLayer, Maria::MapLayer, and Maria::RadioNetworksLayer.
