Detailed Description

Basic TIFF reader.

Note: Any derived reader which does not implement its own openBytesImpl() must fill seriesIFDRange.

Member Function Documentation

void ome::bioformats::in::MinimalTIFFReader::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.

Reimplemented from ome::bioformats::detail::FormatReader.

Reimplemented in ome::bioformats::in::TIFFReader.

References ome::bioformats::detail::FormatReader::close(), and tiff.

Referenced by ome::bioformats::in::TIFFReader::close(), and ~MinimalTIFFReader().

Here is the caller graph for this function:

void ome::bioformats::in::MinimalTIFFReader::getLookupTable	(	dimension_size_type	plane,
		VariantPixelBuffer &	buf
	)		const

virtual

Get the color lookup table associated with an image plane.

If no image planes have been opened, or if isIndexed() returns false, then this may throw an exception.

The VariantPixelBuffer will use the X dimension for the value index and the sub-channel dimension for the color samples (order is RGB). Depending upon the image type, the size of the X dimension may vary. It will typically be 2^8 or 2^16, but other sizes are possible.

Parameters

buf	the destination pixel buffer.
plane	the plane index within the series.

Exceptions

FormatException if a lookup table could not be obtained.

Reimplemented from ome::bioformats::detail::FormatReader.

ome::compat::shared_ptr< ome::bioformats::tiff::TIFF > ome::bioformats::in::MinimalTIFFReader::getTIFF ( )

Get open TIFF file.

Note: This will be null if setId has not been called.

Returns: a reference to the TIFF file.

References tiff.

const ome::compat::shared_ptr< ome::bioformats::tiff::TIFF > ome::bioformats::in::MinimalTIFFReader::getTIFF ( ) const

Get open TIFF file.

Note: This will be null if setId has not been called.

Returns: a reference to the TIFF file.

References tiff.

const ome::compat::shared_ptr< const tiff::IFD > ome::bioformats::in::MinimalTIFFReader::ifdAtIndex ( dimension_size_type plane ) const

protected

Get the IFD index for a plane in the current series.

Parameters

plane the plane index within the series.

Returns: the IFD index.

Exceptions

FormatException if out of range.

References ome::bioformats::detail::FormatReader::getSeries(), ome::bioformats::tiff::ifdIndex(), seriesIFDRange, and tiff.

Referenced by getLookupTable(), and openBytesImpl().

Here is the caller graph for this function:

void ome::bioformats::in::MinimalTIFFReader::initFile ( const boost::filesystem::path & id )

protectedvirtual

Initialize the given file.

This will parse header information, etc. and is called by setId. Most subclasses should override this method to perform initialization operations such as parsing metadata.

Parameters

id	the filename to open.

Exceptions

FormatException if a parsing error occurs processing the file.

See also: ome::bioformats::FormatHandler::setId.

bool ome::bioformats::in::MinimalTIFFReader::isFilenameThisTypeImpl ( const boost::filesystem::path & name ) const

protectedvirtual

isThisType file implementation for readers.

Readers which require opening a file in order to determine its type should override this method with their own implementation. Reader implementations should open the specified file using their preferred method and check its validity.

Parameters

name	the file to open for checking.

Returns: true if the file is valid, false otherwise.

Reimplemented from ome::bioformats::detail::FormatReader.

void ome::bioformats::in::MinimalTIFFReader::openBytesImpl	(	dimension_size_type	plane,
		VariantPixelBuffer &	buf,
		dimension_size_type	x,
		dimension_size_type	y,
		dimension_size_type	w,
		dimension_size_type	h
	)		const

protectedvirtual

Obtain a sub-image of an image plane.

Obtain and copy the sub-image of an image plane from the current series into a VariantPixelBuffer of size

w * h * bytesPerPixel * getRGBChannelCount(channel)

Parameters

plane	the plane index within the series.
buf	the destination 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.

Exceptions

FormatException if there was a problem parsing the metadata of the file.
