Method Detail

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

handleBandRasterRectRead

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

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
