Detailed Description

Tile information for an IFD.

Note: Strips are considered a special case of tiles where the tile width is the image width.

Constructor & Destructor Documentation

ome::files::tiff::TileInfo::TileInfo ( ome::compat::shared_ptr< IFD > ifd )

protected

Constructor.

Parameters

ifd	the directory the tile belongs to.

Member Function Documentation

dimension_size_type ome::files::tiff::TileInfo::bufferSize ( ) const

Get the buffer size needed to contain a single tile.

Returns: the buffer size.

References impl.

dimension_size_type ome::files::tiff::TileInfo::tileColumn ( dimension_size_type index ) const

Get the column index for the given tile index.

Parameters

index the tile index.

Returns: the column index.

References impl.

Referenced by tileCoverage(), and tileRegion().

Here is the caller graph for this function:

dimension_size_type ome::files::tiff::TileInfo::tileColumnCount ( ) const

Get the total number of columns.

Returns: the column count.

References impl.

dimension_size_type ome::files::tiff::TileInfo::tileCount ( ) const

Get the total number of tiles.

Returns: the tile count.

References impl.

std::vector< dimension_size_type > ome::files::tiff::TileInfo::tileCoverage ( PlaneRegion region ) const

Get a list of the tiles covering an image region.

Note: The tiles may extend outside the specified region, and the same area may be covered by multiple tiles if the samples are planar.

Parameters

region the image region to cover.

Returns: a list of tile indexes.

References ome::files::PlaneRegion::h, impl, ome::files::tiff::SEPARATE, tileColumn(), tileIndex(), tileRow(), ome::files::PlaneRegion::w, ome::files::PlaneRegion::x, and ome::files::PlaneRegion::y.

Referenced by ome::files::tiff::IFD::readImage().

Here is the caller graph for this function:

dimension_size_type ome::files::tiff::TileInfo::tileHeight ( ) const

Get the height of a tile.

Returns: the height of a tile.

References impl.

dimension_size_type ome::files::tiff::TileInfo::tileIndex	(	dimension_size_type	x,
		dimension_size_type	y,
		dimension_size_type	s = `0`
	)		const

Get the tile index covering the given coordinates.

Parameters

x	the image column.
y	the image row.
s	the image subchannel.

Returns: the tile index.

References impl.

Referenced by tileCoverage().

Here is the caller graph for this function:

PlaneRegion ome::files::tiff::TileInfo::tileRegion	(	dimension_size_type	index,
		const PlaneRegion &	clip
	)		const

Get the region covered by the given tile index.

If the tile index is invalid, the region will be of zero size. The clip region is a bounding box which will be intersected with the tile index to compute the returned region.

Note: For tiles at the image edges, the region size may differ from the tile size if the image size is not an exact multiple of the tile size. Clip to the full image size to obtain the usable area.

Parameters

index	the tile index.
clip	the clip region.

Returns: the region covered.

PlaneRegion ome::files::tiff::TileInfo::tileRegion ( dimension_size_type index ) const

Get the region covered by the given tile index.

If the tile index is invalid, the region will be of zero size.

Note: This method does not take into account tiles which overlap the edge of the image, and will always return the full tile size including areas outside the image. Use the clip variant of this method to clip tiles to the image edge.

Parameters

index the tile index.

Returns: the region covered.

References impl, tileColumn(), and tileRow().

dimension_size_type ome::files::tiff::TileInfo::tileRow ( dimension_size_type index ) const

Get the row index for the given tile index.

Parameters

index the tile index.

Returns: the row index.

References impl.

Referenced by tileCoverage(), and tileRegion().

Here is the caller graph for this function:

dimension_size_type ome::files::tiff::TileInfo::tileRowCount ( ) const

Get the total number of rows.

Returns: the row count.

References impl.

dimension_size_type ome::files::tiff::TileInfo::tileSample ( dimension_size_type index ) const

Get the sample index for the given tile index.

Note: Only meaningful for planar images.

Parameters

index the tile index.

Returns: the sample index.

References impl.

TileType ome::files::tiff::TileInfo::tileType ( ) const

Get the type of a tile.

Returns: the tile type.

References impl.

dimension_size_type ome::files::tiff::TileInfo::tileWidth ( ) const

Get the width of a tile.

Returns: the width of a tile.
