Constructor Details

TestLoaderImage

public TestLoaderImage(TestLoader loader)

Constructs a TestLoaderImage with a given TestLoader.

Parameters:

loader - The TestLoader to use for non image-related loading.

TestLoaderImage

public TestLoaderImage(TestLoader loader, StackReader stackReader)

Method Details

openChannelFromTestPath

public Channel openChannelFromTestPath(String testPath)

Opens a channel from a test path.

Parameters:

testPath - The test path to the image file.

Returns:

The opened channel.

openChannelFromFilePath

public Channel openChannelFromFilePath(Path filePath)

Opens a channel from a file path.

Parameters:

filePath - The file path to the image file.

Returns:

The opened channel.

openStackFromTestPath

public Stack openStackFromTestPath(String testPath)

Opens a stack from a test path.

Parameters:

testPath - The test path to the image file.

Returns:

The opened stack.

openStackFromFilePath

public Stack openStackFromFilePath(Path filePath)

Opens a stack from a file path.

Parameters:

filePath - The file path to the image file.

Returns:

The opened stack.

compareTwoImages

public boolean compareTwoImages(String path1, String path2) throws FileNotFoundException

Compare two images that are located on the file system in the same test-folder

Parameters:

path1 - first-path to compare

path2 - second-path to compare

Returns:

true if the images are equal (every pixel is identical, and data-types are the same)

Throws:

FileNotFoundException - if one or both of the files cannot be found

compareTwoImages

public static boolean compareTwoImages(TestLoaderImage loader1, String path1, TestLoaderImage loader2, String path2, boolean ignoreResolutionDifferences) throws FileNotFoundException

Compare two images that are located on the file system (possibly in different test folders)

Parameters:

loader1 - loader to use for path1

path1 - first-path to compare

loader2 - loader to use for path2

path2 - second-path to compare

ignoreResolutionDifferences - if true any differences in image-resolution are not considered

Returns:

true if the images are equal (every pixel is identical, and data-types are the same)

Throws:

FileNotFoundException - if one or both of the files cannot be found

openObjectsFromTestPath

public org.anchoranalysis.image.voxel.object.ObjectCollection openObjectsFromTestPath(String testDirectoryPath)

Opens an object collection from a test path.

Parameters:

testDirectoryPath - The test path to the directory containing the object collection.

Returns:

The opened object collection.

openObjectsFromFilePath

public org.anchoranalysis.image.voxel.object.ObjectCollection openObjectsFromFilePath(Path folderPath)

Opens an obj-mask-collection from a path to a file

Parameters:

folderPath - the path to a folder

Returns:

an object-mask collection

Throws:

TestDataLoadException - if data cannot be loaded

compareTwoObjectCollections

public boolean compareTwoObjectCollections(String path1, String path2)

Compare two obj-mask-collection that are located on the file system in the test-folder

Parameters:

path1 - first-path

path2 - second-path

Returns:

true if the object-mask-collection are equal (every object-pixel is identical)

resolveTestPath

public Path resolveTestPath(String testPath)

Resolves a test path to an actual file system path.

Parameters:

testPath - The test path to resolve.

Returns:

The resolved file system path.

doesPathExist

public boolean doesPathExist(String testFilePath)

Checks if a test path exists.

Parameters:

testFilePath - The test path to check.

Returns:

true if the path exists, false otherwise.

getLoader

public TestLoader getLoader()

Delegate loader (for non image-related loading)
