Changed

  • NODATA and TRANSPARENT values are merged. [#41]
    • User visible change: paletted PNG output images will have up to 254 color
      values and a 255th value that is transparent.
    • Internal code changes: removes TRANSPARENT_IDX (254) and uses
      NODATA_IDX (255) in its stead. A color of (0,0,0,0) was previously set to
      both the indexes (254 and 255) in the output PNGs and now only 255 will have
      this value. This change ensures the round-trip from single band to RGBA to
      Paletted PNG is consistent.
