Detailed Description

TIFF writer with support for OME-XML metadata.

Member Function Documentation

void ome::files::out::OMETIFFWriter::close ( bool fileOnly = false )

virtual

Close the currently open file.

An exception may be thrown when closing the file, for example if there are problems flushing any pending writes, or if there are any inconsistencies in the metadata which prevent completing any final writes. The causes are reader- or writer-dependent, and the exception type is dependent upon the implementation details of the reader or writer in use. It is advised to always explicitly close writers, since if this is automatically called at destruction time, any errors will be lost. If an exception is thrown, the object may be left in an inconsistent state and should not be reused.

Parameters

fileOnly close the open file only if true, or else free all internal state if false; only meaningful for readers, since writers will always free all internal state.

Exceptions

On	error; exception type may vary.

void ome::files::out::OMETIFFWriter::fillMetadata ( )

private

Fill MetadataStore with cached metadata.

Set Image, Channel and TiffData elements.

Here is the caller graph for this function:

boost::optional< bool > ome::files::out::OMETIFFWriter::getBigTIFF ( ) const

Query use of BigTIFF support.

If setBigTIFF has not been used to enable or disable BigTIFF explicitly, BigTIFF support will be disabled by default for data less than 4GiB, unless the data would be larger than 4GiB, in which case it will be enabled by default.

Returns: true if BigTIFF support are enabled, or false if disabled.

std::string ome::files::out::OMETIFFWriter::getOMEXML ( const boost::filesystem::path & id )

private

Get OME-XML for embedding into the specified TIFF file.

Parameters

id	the TIFF in which to embed the OME-XML.

Returns: the OME-XML text for embedding.

	)

virtual

Save an image plane.

Write an image plane from a VariantPixelBuffer of size

getSizeX * getSizeY * bytesPerPixel * getRGBChannelCount()

to the current series in the current file.

Parameters

plane	the plane index within the series.
buf	the source pixel buffer.
x	the `X` coordinate of the upper-left corner of the sub-image.
y	the `Y` coordinate of the upper-left corner of the sub-image.
w	the width of the sub-image.
h	the height of the sub-image.

FormatException if any of the parameters are invalid.

void ome::files::out::OMETIFFWriter::setBigTIFF ( boost::optional< bool > big = true )

Set use of BigTIFF support.

Enable or disable use of BigTIFF support for writing files larger than 4GiB.

Note: libtiff must be compiled with BigTIFF support enabled for this option to have any effect.

Parameters

big	`true` to enable or `false` to disable BigTIFF support.

References bigTIFF.

void ome::files::out::OMETIFFWriter::setId ( const boost::filesystem::path & id )

virtual

Set the current file name.

Note this will throw FormatException if there are problems opening the file.

Parameters

id	the filename to open.

Member Data Documentation

ome::compat::shared_ptr< ::ome::xml::meta::MetadataRetrieve> ome::files::out::OMETIFFWriter::originalMetadataRetrieve

protected

Original MetadataRetrieve.

We replace it with the generated OME-XML metadata store.

Todo:: Overriding getMetadataRetrieve will be a cleaner solution, but need to eliminate all direct use of metadataRetrieve in all writers first.
