Release 2.0.4 (Jan 5, 2019) -- compared to 2.0.3

  • Fix potential threadpool deadlock issue that could happen if you were
    (among possibly other things?) simultaneously calling make_texture from
    multiple application threads. #2132
  • ImageInput read_image/scanline/tile fixed subtle bugs for certain
    combination of strides and channel subset reads. #2108
  • TIFF: Fix problems with JPEG compression in some cases. #2117
  • TIFF: Fixed error where reading just a subset of channels, if that subset
    did not include the alpha channel but the image was "unassociated alpha",
    the attempt to automatically associate (i.e. "premultiply" the alpha) upon
    read would get bogus values because the alpha channel was not actually
    read. Now in this case it will not do the premultiplication. So if you are
    purposely reading RGB only from an RGBA file that is specifically
    "unassociated alpha", beware that you will not get the automatic
    premultiplication. #2122
  • Python: define __version__ for the module. #2096
  • IBA::channel_append() previously always forced its result to be float, if
    it wasn't previously initialized. Now it uses the uaual type-merging
    logic, making the result the "widest" type of the inputs. #2095
  • ImageSpec::find_attribute now will retrive "datawindow" and "displaywindow"
    (type int[4] for images int[6] for volumes) giving the OpenEXR-like bounds
    even though there is no such named metadata for OIIO (the results will
    assembled from x, y, width, height, etc.). #2110
  • ImageCache/TextureSystem: more specific error message when tile reads
    appear to be due to the file having changed or been overwritten on disk
    since it was first opened. #2115
  • oiiotool: New -evaloff and -evalon lets you disable and enable
    the expression substitution for regions of arguments (for example, if
    you have an input image filename that contains {} brace characters that
    you want interpreted literally, not evaluated as an expression). #2100
  • oiiotool --dumpdata has more intelligible output for uint8 images. #2124
  • maketx: the -u (update mode) is slightly less conservative now,
    no longer forcing a rebuild of the texture just because the file uses
    a different relative directory path than last time. #2109
  • WebP: fix bug that gave totally incorrect image read for webp images that
    had a smaller width than height. #2120
  • Developer goodies: string_view now adds an optional pos parameter to the
    find_first_of/find_last_of family of methods. #2114
  • Dev goodies: Strutil::wordwrap() now lets you specify the separation
    characters more flexibly (rather than being hard-coded to spaces as
    separators). #2116
