Member Function Documentation

getImageGeometry()

ossimRefPtr< ossimImageGeometry > ossimPointCloudUtilityFilter::getImageGeometry ( )

virtual

Returns the image geometry object associated with this tile source or NULL if not defined.

The geometry contains full-to-local image transform as well as projection (image-to-world). Default implementation returns the image geometry object associated with the next
(left) input source (if any) connected to this source in the chain, or NULL.

Reimplemented from ossimImageSource.

{
   if (!m_util.valid())
      return 0;
   return m_util->m_prodGeom;
}

getNumberOfOutputBands()

virtual ossim_uint32 ossimPointCloudUtilityFilter::getNumberOfOutputBands ( ) const

inlinevirtual

Returns the number of bands in a tile returned from this TileSource.

Reimplemented from ossimImageSource.

Definition at line 35 of file ossimPointCloudUtilityFilter.h.

{ return 1; }

getOutputScalarType()

ossimScalarType ossimPointCloudUtilityFilter::getOutputScalarType ( ) const

inlinevirtual

This will be used to query the output pixel type of the tile source.

Please ignore the argument. It will soon be removed.

Reimplemented from ossimImageSource.

References OSSIM_FLOAT32.

{ return OSSIM_FLOAT32; }

getTile()

bool ossimPointCloudUtilityFilter::getTile ( ossimImageData *  result, ossim_uint32  resLevel  )

virtual

Method to get a tile.

Parameters

result

The tile to stuff. Note The requested rectangle in full image space and bands should be set in the result tile prior to passing. This is the default implementation that is not thread-friendly as it uses the object's tile then simply copies its buffer to the provided tile. Eventually, all image sources should override this method.

Returns

true on success false on error. If return is false, result is undefined so caller should handle appropriately with makeBlank or whatever.

Note

Derived classes should override this method to most efficiently stuff result.
