Example 12 with LayerThing

use of ini.trakem2.tree.LayerThing in project TrakEM2 by trakem2.

the class ProjectTiler method createRetiledSibling.

/**
 * Take a {@link Project}, a size for the image tiles, and a target directory,
 * and create a new copy of the current project in that folder but with the underlying
 * images converted to tiles with a translation-only transform (saved as zipped TIFFs,
 * with extension ".tif.zip").
 * The new, returned {@link Project} represents the given project but with much
 * simpler transformations (just translation) for the images and a defined size for
 * the latter, which helps a lot regarding storage space of the XML (and parsing and
 * saving time) and performance when browsing layers (keep in mind that, for a 32k x 32k image,
 * at 100% zoom one would have to load a 32k x 32k image and render just a tiny bit
 * of it). The copied Project preserves the ID of the {@link Layer}s of the original
 * {@link Project}, as well as the dimensions; this means the copy is a sibling of
 * the original, and it is possible to send segmentations from one to the other "as is"
 * (directly, without having to transform along with the images which would not be possible).
 *
 * Image files are stored as
 *
 * The non-image objects of the given project are copied into the new project as well.
 *
 * @param srcProject The project to create a sibling of.
 * @param targetDirectory The directory in which to create all the necessary data and mipmap folders for the new Project.
 * @param tileWidth The width of the tiles to create for the data of the new project.
 * @param tileHeight The height of the tiles.
 * @param exportImageType Any of {@link ImagePlus#GRAY8}, {@link ImagePlus#GRAY16} or {@link ImagePlus#COLOR_RGB}, otherwise an {@link IllegalArgumentException} is thrown.
 * @param onlyVisibleImages Whether to consider visible images only.
 * @param nExportThreads Number of layers to export in parallel. Use a small number when original images are huge (such as larger than 4096 x 4096 pixels).
 * @param createMipMaps Whether to generate the mipmaps when done or not.
 *
 * @throws Exception IllegalArgumentException When {@code exportImageType} is not {@link ImagePlus#GRAY16} or {@link ImagePlus#COLOR_RGB}, or when the directory exists and cannot be written to.
