Constructor Detail

StyledTiledMapRenderer

public StyledTiledMapRenderer(java.awt.Graphics2D g,
                              NavigatableComponent nc,
                              boolean isInactiveMode)

Constructs a new StyledMapRenderer.

Parameters:

g - the graphics context. Must not be null.

nc - the map viewport. Must not be null.

isInactiveMode - if true, the paint visitor shall render OSM objects such that they look inactive. Example: rendering of data in an inactive layer using light gray as color only.

Throws:

java.lang.IllegalArgumentException - if g is null

java.lang.IllegalArgumentException - if nc is null

Method Detail

render

public void render(OsmData<?,?,?,?> data,
                   boolean renderVirtualNodes,
                   Bounds bounds)

Description copied from interface: Rendering

Renders the OSM data in data

Specified by:

render in interface Rendering

Overrides:

render in class StyledMapRenderer

Parameters:

data - the data set to be rendered

renderVirtualNodes - if true, renders virtual nodes. Otherwise, ignores them.

bounds - the bounding box for the data to be rendered. Only objects within or intersecting with bbox are rendered

setCache

public void setCache(Bounds box,
                     org.apache.commons.jcs3.access.CacheAccess<TileZXY,ImageCache> cache,
                     int zoom,
                     java.util.function.Consumer<TileZXY> notifier)

Set the cache for this painter. If not set, this acts like StyledMapRenderer.

Parameters:

box - The box we will be rendering -- any jobs for tiles outside of this box will be cancelled

cache - The cache to use

zoom - The zoom level to use for creating the tiles

notifier - The method to call when a tile has been updated. This may or may not be called in the EDT.

cancelImageFuture

private static void cancelImageFuture(org.apache.commons.jcs3.access.CacheAccess<TileZXY,ImageCache> cache,
                                      TileZXY key,
                                      ImageCache value)

Cancel a job for a tile

Parameters:

cache - The cache with the job

key - The tile key

value - The ImageCache to remove and cancel

generateTiles

private java.awt.image.BufferedImage generateTiles(OsmData<?,?,?,?> data,
                                                   java.util.Collection<TileZXY> tiles,
                                                   int tileSize)

Generate tile images

Parameters:

data - The data to generate tiles from

tiles - The collection of tiles to generate (note: there is currently a bug with multiple tiles)

tileSize - The size of the tile image

Returns:

The image for the tiles passed in

createCompatibleImage

private static java.awt.image.BufferedImage createCompatibleImage(NavigatableComponent nc,
                                                                  int width,
                                                                  int height)

generateRenderArea

private static Bounds generateRenderArea(java.util.Collection<TileZXY> tiles)

Generate the area for rendering

Parameters:

tiles - The tiles that we want to render

Returns:

The generated render area with BUFFER_TILES on all sides.
