virtual bool ome::bioformats::FormatReader::isInterleaved ( ) const
pure virtual

Get whether or not the channels are interleaved.

This method exists because X and Y must appear first in the dimension order. For interleaved data, getDimensionOrder() returns XYCTZ or XYCZT and this method returns true.

Note that this flag returns whether or not the data returned by openBytes() is interleaved. In most cases, this will match the interleaving in the original file, but for some formats (e.g. TIFF) channel re-ordering is done internally and the return value of this method will not match what is in the original file.

Returns
true if the channels are interleaved, false otherwise.

+ Here is the caller graph for this function:

virtual bool ome::bioformats::FormatReader::isInterleaved ( dimension_size_type  subC) const

Parameters
subCthe subchannel index.
