[ome-users] Release of Bio-Formats 6.0.0

[David Gault (Staff)]

Dear all,

Today we are releasing Bio-Formats 6.0.0  This is a major update that includes support for the updated OME-TIFF file format<http://docs.openmicroscopy.org/latest/ome-model/ome-tiff/specification.html>, which now supports multi-resolution tiled images (so-called pyramidal file format). For more info, see http://blog.openmicroscopy.org/file-formats/community/2018/11/29/ometiffpyramid/.  This new version of Bio-Formats also includes support for the KLB format for light sheet microscopy.

  *   Java 8 is now the minimum supported version

  *
Sub-resolution reading:
     *
added MetadataList and CoreMetadataList classes
     *

     *
deprecated getCoreMetadataList, seriesToCoreIndex, coreIndexToSeries, getCoreIndex and setCoreIndex in IFormatWriter
  *

  *
* Tiled writing API changes:
     *
updated IFormatWriter to use setTileSizeX(0) and setTileSizeY(0) as a way to disable tiling (breaking)
     *
updated FormatWriter to set 0 as the default values of getTileSizeX() and getTileSizeY (breaking)
  *
IFormatWriter.getCompressionTypes now returns the types for the selected writer only
  *
Metadata handling:
     *
added getter methods to MetadataTools for retrieving OME enumerations by value
