public class ProjectTiler extends Object
|Constructor and Description|
|Modifier and Type||Method and Description|
Return a lazy sequence of Rectangle instances, each specifying a tile that contains at least parts of one Patch.
public static final Project createRetiledSibling(Project srcProject, String targetDirectory, int tileWidth, int tileHeight, int exportImageType, boolean onlyVisibleImages, int nExportThreads, boolean createMipMaps) throws Exception
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
Projectrepresents 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
Layers of the original
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.
srcProject- The project to create a sibling of.
targetDirectory- The directory in which to create all the necessary data and mipmap folders for the new Project.
tileWidth- The width of the tiles to create for the data of the new project.
tileHeight- The height of the tiles.
exportImageType- Any of
ImagePlus.COLOR_RGB, otherwise an
onlyVisibleImages- Whether to consider visible images only.
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).
createMipMaps- Whether to generate the mipmaps when done or not.
Exception- IllegalArgumentException When
ImagePlus.COLOR_RGB, or when the directory exists and cannot be written to.
