Constructor Details

OpenslideImageServer

public OpenslideImageServer(URI uri,
 String... args)
                     throws IOException

Create an ImageServer using OpenSlide for the specified file.

The only supported arg is --no-crop, to specify that any bounding box should not be applied (which was the default in QuPath <= v0.1.2).

Parameters:

uri -

args -

Throws:

IOException

Method Details

getURIs

public Collection<URI> getURIs()

Description copied from interface: ImageServer

Get the URIs for images required for this server. In the simplest case, this is a singleton list returning a URI representing a local file. However, some ImageServers may not have an associated URI at all, whereas others may depend upon multiple URIs (e.g. if concatenating images).

Note: A URI alone may not be sufficient to recreate even a simple ImageServer; see ImageServer.getBuilder().

Returns:

createID

protected String createID()

Description copied from class: AbstractImageServer

Create a unique ID for the server, which can be returned as the default value of AbstractImageServer.getPath(). A suggested implementation is

 getClass().getName() + ": " + URI + parameters

This will be called on demand whenever AbstractImageServer.getPath() is first required.

Specified by:

createID in class AbstractImageServer<BufferedImage>

Returns:

close

public void close()

Specified by:

close in interface AutoCloseable

Overrides:

close in class AbstractImageServer<BufferedImage>

dumpMetadata

public String dumpMetadata()

Retrieve a JSON string representation of the properties, as stored as key-value pairs by OpenSlide.

Returns:

getServerType

public String getServerType()

Description copied from interface: ImageServer

A string describing the type of server, for example the name of the library used (Openslide, Bioformats...)

Returns:

readTile

public BufferedImage readTile(TileRequest tileRequest)
                       throws IOException

Description copied from class: AbstractTileableImageServer

Read a single image tile.

Specified by:

readTile in class AbstractTileableImageServer

Parameters:

tileRequest -

Returns:

Throws:

IOException

getAssociatedImageList

public List<String> getAssociatedImageList()

Description copied from interface: ImageServer

Get a list of 'associated images', e.g. thumbnails or slide overview images.

Each associated image is simply a T that does not warrant (or require) a full ImageServer, and most likely would never be analyzed.

Specified by:

getAssociatedImageList in interface ImageServer<BufferedImage>

Overrides:

getAssociatedImageList in class AbstractImageServer<BufferedImage>

Returns:

See Also:

• ImageServer.getAssociatedImage(String)

createServerBuilder

protected ImageServerBuilder.ServerBuilder<BufferedImage> createServerBuilder()

Description copied from class: AbstractImageServer

Create a ServerBuilder, which can be used to construct an identical ImageServer. This should also include the current metadata. It is permissible to return null for an ImageServer that cannot be recreated via a ImageServerBuilder.ServerBuilder.

Specified by:

createServerBuilder in class AbstractImageServer<BufferedImage>

Returns:

getAssociatedImage

public BufferedImage getAssociatedImage(String name)

Description copied from interface: ImageServer

Get the image for a given associated image name.

Specified by:

getAssociatedImage in interface ImageServer<BufferedImage>

Overrides:

getAssociatedImage in class AbstractImageServer<BufferedImage>

Parameters:

name -

Returns:

See Also:

• ImageServer.getAssociatedImageList()

getOriginalMetadata

public ImageServerMetadata getOriginalMetadata()

Description copied from interface: ImageServer

Get the original metadata read during creation of the server. This may or may not be correct.

Returns:

See Also:

• ImageServer.getMetadata()

getArgs

public List<String> getArgs()

Get the optional arguments used to construct this server.

Returns:

an unmodifiable list of string arguments, or an empty list if no arguments are used
