Detailed Description

RasterData is a purely abstract interface to be implemented by classes that want to be displayed in a LayerComponent. It asks for features like providing access to size and data information as well as possibilities for data loading and unloading.

Note:

Classes that implement the RasterData interface need to have their pixel data represented as a normalized, two-dimensional array of double in row-major order!

Member Function Documentation

virtual void vrvis::RasterData::getSizeInPixels (  int &  rPixelsX, int &  rPixelsY )  const [pure virtual]

Return the size of the rastered data in pixels. Parameters: [out]  rPixelsX  Return width in pixels. [out]  rPixelsY  Return height in pixels. Implemented in vrvis::ImageBand< DataTypeT >.

virtual double* vrvis::RasterData::getValues (  void   )  const [pure virtual]

Return a pointer to the memory where the pixel values are stored. The RasterData should be loaded first. Returns: Pointer to the double data storage. See also: load() Implemented in vrvis::ImageBand< DataTypeT >.

virtual void vrvis::RasterData::load (  void   )  [pure virtual]

Load the pixel data the implementing class represents into memory. Implemented in vrvis::ImageBand< DataTypeT >.

virtual void vrvis::RasterData::unload (  void   )  [pure virtual]

Free all memory allocated by the pixel data. Implemented in vrvis::ImageBand< DataTypeT >.
