If this evaluates to True, then the comment is replaced by ``# doctest: +SKIP``. If False, then the comment is just removed. The expression is evaluated in the ``globals`` scope of `func`. For example, if the module global ``HAVE_AMODULE`` is False, and module global ``HAVE_BMODULE`` is False, the returned function will have docstring:: >>> something # doctest: +SKIP >>> something + else # doctest: +SKIP >>> something # doctest: +SKIP  z# doctest: +SKIP) __doc__splitSKIP_REmatchappendgroupseval __globals__AttributeError__init__join)funclines new_linesliner0codespaceexprs r&doctest_skip_parserr?Cs0 LL  t $EI d# =   T " !LLNT 9D**++|&88 !"99Y'DL K 9D--3344|&88 9s"!B005C('C(cSU;aSU-n[USS9nURnSSS5 [R"WXS9 [R"XAS9n[ R "U5 U$!,(df  NP=f![a U$f=f)z/Save and read an image using a specified plugin.F)suffixdeleteN)plugin)rnamerimsaveimreadosremove Exception)imagerDrB temp_filefnamenews r& roundtriprOrs &v 6% 8I 9IIeU* ))E )C  % J 9 8   J s A-A>- A;> B  B c[[R"55n[X U5n[R "X#5 US:n[X@U5n[R "XER [55 [U5n[X`U5n[R "Xr5 [U5nUR5S;a(US-n[XU5n [R "X5 O,[XU5n [R "U [U55 [U5n [XU5n [R "X5 g)zwCheck roundtrip behavior for color images.

This decorator is useful to ensure that separate threads execute concurrently and correctly while releasing the GIL. It is currently skipped when running on WASM-based platforms, as the threading module is not supported. Parameters ---------- workers : int, optional The number of times the function is run in parallel. warnings_matching : list or None This parameter is passed on to `expected_warnings` so as not to have race conditions with the warnings filters. A single `expected_warnings` context manager is used for all threads. If None, then no warnings are checked. rcr>^^[(aT$SSKm[R"T5UUUU4Sj5nU$)Nrc4>[T5 /n[TS- 5H$nTRTXS9nURU5 M& UHnUR 5 M T"U0UD6 UHnUR 5 M SSS5 g!,(df  g=f)Nr)targetargskwargs)rrangeThreadr1startr7) rzr{threadsithreadr8 threadingwarnings_matchingworkerss r&inner/run_in_parallel..wrapper..inners"#45w{+A&--T-TFNN6*,&FLLN&d%f%%FKKM&655s A3B  B)rr functoolswraps)r8rrrrs` @r&wrapper run_in_parallel..wrappers2 7K   "  " r(r )rrrs`` r&run_in_parallelrs* Q;;0 Nr()offsetc \Sn[R"5SRnURU-nURR nUSU3nUHVnUR SUR3nSUSUSURRSUR3n X:XaMQU 5e g) aAssert correct stacklevel of captured warnings. When scikit-image raises warnings, the stacklevel should ideally be set so that the origin of the warnings will point to the public function that was called by the user and not necessarily the very place where the warnings were emitted (which may be inside some internal function). This utility function helps with checking that the stacklevel was set correctly on warnings captured by `pytest.warns`. Parameters ---------- warnings : collections.abc.Iterable[warning.WarningMessage] Warnings that were captured by `pytest.warns`. offset : int, optional Offset from the line this function is called to the line were the warning is supposed to originate from. For multiline calls, the first line is relevant. Defaults to -1 which corresponds to the line right above the one where this function is called. Raises ------ AssertionError If a warning in `warnings` does not match the expected line number or file name. Examples -------- >>> def test_something(): ... with pytest.warns(UserWarning, match="some message") as record: ... something_raising_a_warning() ... assert_stacklevel(record) ... >>> def test_another_thing(): ... with pytest.warns(UserWarning, match="some message") as record: ... iam_raising_many_warnings( ...
