 ExecutionTimeRecorder executionTimeRecorder)

Method Details

numberSeries

public int numberSeries()

Description copied from interface: OpenedImageFile

The number of series (distinct sets of images) in the image-file.

Specified by:

numberSeries in interface OpenedImageFile

Returns:

the number of series.

open

public TimeSeries open(int seriesIndex,
 Logger logger)
                throws ImageIOException

Description copied from interface: OpenedImageFile

Open when we don't have a specific-type.

Specified by:

open in interface OpenedImageFile

Parameters:

seriesIndex - the index of the series of the open, zero-indexed.

logger - the logger.

Returns:

a time-sequence of images.

Throws:

ImageIOException - if an error occurs reading the image during this operation.

channelNames

public Optional<List<String>> channelNames(Logger logger)

Description copied from interface: OpenedImageFile

The names of each channel, if they are known.

Specified by:

channelNames in interface OpenedImageFile

Parameters:

logger - the logger.

Returns:

a list of the names, which should correspond (and have the same number of items) as OpenedImageFile.numberChannels(Logger).

numberChannels

public int numberChannels(Logger logger)
                   throws ImageIOException

Description copied from interface: OpenedImageFile

The number of channels in the image-file e.g. 1 for grayscale, 3 for RGB.

Specified by:

numberChannels in interface OpenedImageFile

Parameters:

logger - the logger.

Returns:

the number of channels.

Throws:

ImageIOException - if an error occurs reading the image to determine this information.

bitDepth

public int bitDepth(Logger logger)
             throws ImageIOException

Description copied from interface: OpenedImageFile

The bit-depth of the image voxels e.g. 8 for 8-bit, 16 for 16-bit etc.

Specified by:

bitDepth in interface OpenedImageFile

Parameters:

logger - the logger.

Returns:

the bit-depth.

Throws:

ImageIOException - if an error occurs reading the image to determine this information.

isRGB

public boolean isRGB(Logger logger)
              throws ImageIOException

Description copied from interface: OpenedImageFile

Whether the image-file has RGB encoded voxels.

Specified by:

isRGB in interface OpenedImageFile

Parameters:

logger - the logger.

Returns:

true if the image has RGB or RGBA encoded voxels, false otherwise.

Throws:

ImageIOException - if an error occurs reading the image to determine this information.

numberFrames

public int numberFrames(Logger logger)
                 throws ImageIOException

Description copied from interface: OpenedImageFile

The number of frames in the image-file i.e. distinct images for a particular time-point.

Specified by:

numberFrames in interface OpenedImageFile

Parameters:

logger - the logger.

Returns:

the number of frames.

Throws:

ImageIOException - if an error occurs reading the image to determine this information.

timestamps

public ImageTimestampsAttributes timestamps()
                                     throws ImageIOException

Description copied from interface: OpenedImageFile

The timestamps and file-attributes associated with the image.

Specified by:

timestamps in interface OpenedImageFile

Returns:

timestamps and file-attributes, either newly-created or reused.

Throws:

ImageIOException - if an error occurs reading the image to determine this information.

close

public void close()
           throws ImageIOException

Description copied from interface: OpenedImageFile

Closes the opened image-file, removing any intermediate data-structures.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface OpenedImageFile

Throws:

ImageIOException

dimensionsForSeries

public Dimensions dimensionsForSeries(int seriesIndex,
 Logger logger)
                               throws ImageIOException

Description copied from interface: OpenedImageFile

The Dimensions associated with a particular series.

Specified by:

dimensionsForSeries in interface OpenedImageFile

Parameters:

seriesIndex - the index of the series.

logger - a logger for any non-fatal errors. Fatal errors throw an exception.

Returns:

the corresponding dimensions.

Throws:

ImageIOException - if any filesystem-related input-output failure occurs.

pyramid

public Optional<ImagePyramidMetadata> pyramid()
                                       throws ImageIOException
