Detailed Description

Interface with callback methods for the raster data retriever to call.

There is usually no need to make a user implementation. An implementation to call the methods on is provided by the raster model implementation that has been created using either a MultilevelTiledRasterModelBuilder or a QuadTreeRasterModelBuilder.

Since

2022.1

Member Function Documentation

onCanceled()

virtual void luciad::IMultilevelTiledRasterDataRetrieverCallback::onCanceled ( MultilevelTileCoordinate  tileCoordinate )

pure virtual

Call this method when the request for the raster tile data was canceled.

Parameters

tileCoordinate

the tile coordinate for which the request was canceled.

onDataAvailable()

virtual void luciad::IMultilevelTiledRasterDataRetrieverCallback::onDataAvailable ( MultilevelTileCoordinate  tileCoordinate, const DataEntity &  data  )

pure virtual

Call this method when you have retrieved the raster tile data in its raw form.

Supported mime types for the raster tile data:

Imagery:

• image/png
• image/jpeg
• image/tiff (containing RGB(A))

Elevation:

• image/tiff (containing a single channel with floating point data)

Parameters

tileCoordinate	the tile coordinate for which the raster tile data was retrieved.
data	the raster tile data.

onDataNotAvailable()

virtual void luciad::IMultilevelTiledRasterDataRetrieverCallback::onDataNotAvailable ( MultilevelTileCoordinate  tileCoordinate )

pure virtual

Call this method when there is no data available for the tile coordindate.

Parameters

tileCoordinate

the tile coordinate for which there is no raster tile data.

onError()

virtual void luciad::IMultilevelTiledRasterDataRetrieverCallback::onError ( MultilevelTileCoordinate  tileCoordinate, const std::string &  message  )

pure virtual

Call this method when there is an error to retrieve the raster tile data.

Parameters

tileCoordinate	the tile coordinate for which there is no raster tile data.
message	a message to detail what went wrong.

onImageAvailable()

virtual void luciad::IMultilevelTiledRasterDataRetrieverCallback::onImageAvailable ( MultilevelTileCoordinate  tileCoordinate, const std::shared_ptr< Image > &  image  )

pure virtual

Call this method when you have retrieved the raster tile data and have decoded it as an image.

Supported image types:

Imagery:

• PixelFormat::Rgb888
• PixelFormat::Rgba8888
• PixelFormat::Rgb565

Elevation:

• PixelFormat::Float32

Parameters

tileCoordinate	the tile coordinate for which the raster tile data was retrieved.
image	the raster tile data decoded into an image.
