Detailed Description

Tagged Image File Format (TIFF).

This class is the primary class for reading and writing TIFF files. Use the static open() method to get a working instance. This instance may be used to get IFD instances and then access to image metadata and pixel data.

Member Function Documentation

TIFF::iterator ome::files::tiff::TIFF::begin ( )

Get the first image file directory.

Returns: an iterator referring to the first image file directory

References getDirectoryByIndex().

Referenced by directoryCount().

Here is the caller graph for this function:

TIFF::const_iterator ome::files::tiff::TIFF::begin ( ) const

Get the first image file directory.

Returns: an iterator referring to the first image file directory

References getDirectoryByIndex().

void ome::files::tiff::TIFF::close ( )

Close the TIFF file.

Note that this will be done automatically when the destructor runs. Any further method calls using this object or any child IFD will throw an Exception.

References impl.

directory_index_type ome::files::tiff::TIFF::directoryCount ( ) const

Get the total number of IFDs.

Returns: the IFD count.

References begin(), end(), and impl.

TIFF::iterator ome::files::tiff::TIFF::end ( )

Get the last+1 image file directory.

Returns: an iterator referring to the last+1 image file directory.

Referenced by directoryCount().

Here is the caller graph for this function:

TIFF::const_iterator ome::files::tiff::TIFF::end ( ) const

Get the last+1 image file directory.

Returns: an iterator referring to the last+1 image file directory.

ome::compat::shared_ptr< IFD > ome::files::tiff::TIFF::getCurrentDirectory ( ) const

Get the currently active IFD.

Returns: the IFD.

Exceptions

an	Exception if the IFD could not be accessed.

References ome::files::tiff::IFD::current().

Referenced by writeCurrentDirectory().

Here is the caller graph for this function:

ome::compat::shared_ptr< IFD > ome::files::tiff::TIFF::getDirectoryByIndex ( directory_index_type index ) const

Get an IFD by its index.

Parameters

index the directory index.

Returns: the IFD.

Exceptions

an	Exception if the index is invalid or could not be accessed.

References ome::files::tiff::Sentry::error(), impl, and ome::files::tiff::IFD::openIndex().

Referenced by begin().

Here is the caller graph for this function:

ome::compat::shared_ptr< IFD > ome::files::tiff::TIFF::getDirectoryByOffset ( offset_type offset ) const

Get an IFD by its offset in the file.

Parameters

offset the directory offset.

Returns: the IFD.

Exceptions

an	Exception if the offset is invalid or could not be accessed.

References ome::files::tiff::Sentry::error(), impl, and ome::files::tiff::IFD::openOffset().

TIFF::wrapped_type * ome::files::tiff::TIFF::getWrapped ( ) const

Get the underlying libtiff ::TIFF instance.

If there is any need to use the libtiff C interface to access any functionality not exposed through these C++ wrapper classes, this will provide a pointer to the handle.

Note: Due to not including the libtiff C headers the ::TIFF type isn't available here. After including the main <tiffio.h> header, cast the return value to the correct type:

* ::TIFF *tiff = reinterpret_cast< ::TIFF *>(myfile.getWrapped());
*

Returns: an opaque pointer to the wrapped ::TIFF instance.

References impl.

Referenced by registerImageJTags().

Here is the caller graph for this function:

ome::compat::shared_ptr< TIFF > ome::files::tiff::TIFF::open	(	const boost::filesystem::path &	filename,
		const std::string &	mode
	)

static

Open a TIFF file for reading or writing.

Note: There are additional open flags, documented in TIFFOpen(3).

Parameters

filename	the file to open.
mode	the file open mode (`r` to read, `w` to write or `a` to append).

Returns: the the open TIFF.

Exceptions

an	Exception on failure.

Referenced by ome::files::in::OMETIFFReader::getTIFF(), and ome::files::out::OMETIFFWriter::setId().

Here is the caller graph for this function:

ome::files::tiff::TIFF::operator bool ( )

Check if the TIFF file is valid.

Returns: true if the file is open and available for reading and writing, or false if closed or invalid.

References impl.

void ome::files::tiff::TIFF::writeCurrentDirectory ( )

Write the currently active IFD.

The pixel data accompanying this IFD must have been written using IFD::writeImage() prior to calling this method, or else the TIFF tags for strip and tile offsets will be incomplete and the file will fail to read.
