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);
