NAME

       Geo::GDAL::FFI::Band - A GDAL raster band

SYNOPSIS

DESCRIPTION

       A band (channel) in a raster dataset. Use the Band method of a dataset object to obtain a
       band object.

METHODS

   GetDataType
        my $datatype = $band->GetDataType;

   GetSize
        my @size = $band->GetSize;

   GetBlockSize
        my @size = $band->GetBlockSize;

   GetNoDataValue
        my $nodata = $band->GetNoDataValue;

   SetNoDataValue
        $band->SetNoDataValue($value);

       Calling the method without arguments deletes the nodata value.

        $band->SetNoDataValue;

   Read
        my $data = $band->Read($xoff, $yoff, $xsize, $ysize, $bufxsize, $bufysize);

       All arguments are optional. If no arguments are given, reads the whole raster band into a
       2D Perl array. The returned array is an array of references to arrays of row values.

   ReadBlock
        my $data = $band->ReadBlock($xoff, $yoff, @blocksize, $datatype);

       Reads a block of data from the band and returns it as a Perl 2D array. @blocksize and
       $datatype (an integer) are optional and obtained from the GDAL raster object if not given.

   Write
        $band->Write($data, $xoff, $yoff, $xsize, $ysize);

   WriteBlock
        $band->WriteBlock($data, $xoff, $yoff);

   SetPiddle
        $band->SetPiddle($pdl, $xoff, $yoff, $xsize, $ysize);

       Read data from a piddle into this Band.

   GetPiddle
        $band->GetPiddle($xoff, $yoff, $xsize, $ysize, $xdim, $ydim);

       Read data from this Band into a piddle.

   GetColorInterpretation
        my $ci = $band->GetColorInterpretation;

   SetColorInterpretation
        $band->SetColorInterpretation($ci);

   GetColorTable
        my $color_table = $band->GetColorTable;

       Returns the color table as an array of arrays. The inner tables are colors [c1...c4].

   SetColorTable
        $band->SetColorTable($color_table);
