Writer Compress Decompress

Description

workflow using the TiffWriter? to write and TiffReader? to read

  • read files
  • write full plane, m1 = Md5(plane)
  • read the plane back m2 = Md5(plane)
  • m1 != m2

Writing part tested using no compression, in that case m1 = m2.

Note: tests written for all implemented codec, to check the compress-decompress round trip outside the writer.

(In [7a30786c62c4452f2dab0be27774e8a0f1b42b39/bioformats.git]) Closes #4660, #4706, #4727. See #4134, #4705, #4714.

  • ts-merge: Merge fixes and TiffWriterTest? Ant target. Test writing of tiles, fix remaining bugs in TiffSaver. Add control to add the series to the list only once. Fixed tile based writing. Add method to support IFD. Implement method to set the codec options. Add ability to specify codec options to writer and add tests. Review codec. Support writing of tiles with width less that the image's width.
