Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static interface	ExportScalePyramid.AfterEachPlane	Callback that is called after each "plane of blocks" is written, giving the opportunity to clear caches, etc.
static interface	ExportScalePyramid.DatasetIO<D,T extends net.imglib2.type.NativeType<T>>	Writing and reading back data for each resolution level.
static class	ExportScalePyramid.DefaultLoopbackHeuristic	Simple heuristic: use loopback image loader if saving 8 times or more on number of pixel access with respect to the original image.
static interface	ExportScalePyramid.LoopbackHeuristic	A heuristic to decide for a given resolution level whether the source pixels should be taken from the original image or read from a previously written resolution level in the output dataset.

Write an image to a chunked mipmap representation.

Type Parameters:

T - Pixel type

D - Dataset handle

Parameters:

img - the image to be written.

type - instance of the pixel type of the image.

mipmapInfo - contains for each mipmap level of the setup, the subsampling factors and block sizes.

io - writer for image blocks.

executorService - ExecutorService where block-creator tasks are submitted.

numThreads - How many block-creator tasks to run in parallel. (This many tasks are submitted to the @code

loopbackHeuristic - heuristic to decide whether to create each resolution level by reading pixels from the original image or by reading back a finer resolution level already written to the hdf5. may be null (in this case always use the original image).

afterEachPlane - this is called after each "plane of blocks" is written, giving the opportunity to clear caches, etc. may be null.

progressWriter - completion ratio and status output will be directed here. may be null.

Throws:

IOException
