• Improve argument parsing and help text by @jmuhlich in #128
• Update scikit-image to 0.19 by @jmuhlich in #130

Full Changelog: v1.15.3...v1.16.0

v1.15.3

Bugfixes

Full Changelog: v1.15.2...v1.15.3

v1.15.2

Bugfixes

• Fix some bugs in our usage of tifffile by @jmuhlich in #120

Full Changelog: v1.15.1...v1.15.2

v1.15.1

Bugfixes

• Work around pyjnius mishandling of bool args by @jmuhlich in #118
  (Fixes the error TypeError: Invalid instance of 'java/lang/Integer' passed for a 'java/lang/Boolean' when using pyjnius>=1.4)

Full Changelog: v1.15.0...v1.15.1

v1.15.0

New features

• OME-TIFF files written by Ashlar conform to the official OME-TIFF pyramid specification rather than the unofficial interim pyramid format previously written. (#93)
• The -o argument supersedes the -f and --pyramid arguments by allowing the destination filename and format to be included in the path. For example, -o /path/to/output.ome.tif will write an OME-TIFF pyramid at the given location, (#93)

Bugfixes and other improvements

• Keep the JVM heap (used by the BioFormats file reader) from growing too much (#114)
• Memory usage is dramatically reduced. The current usage is the total size of the first cycle's reference channel tiles plus a fixed overhead of about 400 MB.

Full Changelog: v1.14.1...v1.15.0

v1.14.1

What's Changed

• Fix parsing of channel in filenames by @jmuhlich in #112
• Website updates by @jtefftHiTS

v1.14.0

New features

• Added --flip-mosaic-x and --flip-mosaic-y arguments to allow flipping output mosaic image. (#90)

v1.13.1

Internal enhancements

• Update README to include --flip-x and --flip-y arguments in the usage summary and refresh the installation instructions. (#83, #89)
• Allow ashlar.reg.plot_* functions that can display the stitched image to use a downsampled image. This makes these functions practical for large images which would cause matplotlib.imshow to struggle. (#86)
• The preview_slide script now downsamples images by a factor of 10 by default for improved performance. The factor can be adjusted with the -d argument. (#86)
