    • handleBandRasterLineRead

      boolean handleBandRasterLineRead(Band destBand, int destOffsetX, int destOffsetY, int destWidth, int destHeight, ProductData destBuffer, int destBufferPos)
      Called when a complete line has successfully been read.
      Parameters:
      destBand - the destination band which identifies the data source from which to read the sample values
      destOffsetX - the X-offset in the band's raster co-ordinates
      destOffsetY - the current line (Y-offset) in the band's raster co-ordinates
      destWidth - the width of region to be read given in the band's raster co-ordinates
      destHeight - the height of region to be read given in the band's raster co-ordinates
      destBuffer - the destination buffer which receives the sample values to be read
      destBufferPos - the offset within the buffer where the line which just has been read in is stored

      boolean handleBandRasterRectRead(Band destBand, int destOffsetX, int destOffsetY, int destWidth, int destHeight, ProductData destBuffer)
      Parameters:
      destBand - the destination band which identifies the data source from which to read the sample values
      destOffsetX - the X-offset in the band's raster co-ordinates
      destOffsetY - the current line (Y-offset) in the band's raster co-ordinates
      destWidth - the width of region to be read given in the band's raster co-ordinates
