when i come back,just for fun, 재미를 위해 다음엔 주제를 바꿔보겠어 the subject will be alternative history.
À mon retour, pour s'amuser, le sujet sera l'uchronie.

this function is guaranteed to return a color index for a requested color, either the exact color or the closest possible alternative.
imagecolorresolvealpha() retourne toujours un index de couleur, disponible dans la palette de l'image im: soit c'est la couleur exacte, soit c 'est la meilleure approximation.

although lookbehind assertions must match fixed length strings, each alternative branch of a lookbehind assertion can match a different length of string. perl 5.005 requires them all to have the same length.
lors de la préparation du masque, il est souvent plus pratique d'utiliser les séquences d'échappement suivantes, plutôt que le caractère binaire qu 'elle représente:

an assertion is a test on the characters following or preceding the current matching point that does not actually consume any characters. the simple assertions coded as \b, \b, \a, \z, \z, ^ and $are described above. more complicated assertions are coded as subpatterns. there are two kinds: those that look ahead of the current position in the subject string, and those that look behind it. an assertion subpattern is matched in the normal way, except that it does not cause the current matching position to be changed. lookahead assertions start with (?= for positive assertions and (?! for negative assertions. for example, \w+(?=;) matches a word followed by a semicolon, but does not include the semicolon in the match, and foo(?!bar) matches any occurrence of "foo" that is not followed by "bar". note that the apparently similar pattern (?!foo)bar does not find an occurrence of "bar" that is preceded by something other than "foo"; it finds any occurrence of "bar" whatsoever, because the assertion (?!foo) is always true when the next three characters are "bar". a lookbehind assertion is needed to achieve this effect. lookbehind assertions start with (? = for positive assertions and (?! for negative assertions. for example, (? !foo)bar does find an occurrence of "bar" that is not preceded by "foo". the contents of a lookbehind assertion are restricted such that all the strings it matches must have a fixed length. however, if there are several alternatives, they do not all have to have the same fixed length. thus (? =bullock_bar_donkey) is permitted, but (? !dogs?_bar_cats?) causes an error at compile time. branches that match different length strings are permitted only at the top level of a lookbehind assertion. this is an extension compared with perl 5.005, which requires all branches to match the same length of string. an assertion such as (? =ab(c_bar_de)) is not permitted, because its single top-level branch can match two different lengths, but it is acceptable if rewritten to use two top-level branches: (? =abc_bar_abde) the implementation of lookbehind assertions is, for each alternative, to temporarily move the current position back by the fixed width and then try to match. if there are insufficient characters before the current position, the match is deemed to fail. lookbehinds in conjunction with once-only subpatterns can be particularly useful for matching at the ends of strings; an example is given at the end of the section on once-only subpatterns. several assertions (of any sort) may occur in succession. for example, (? =\d{3})(? !999)foo matches "foo" preceded by three digits that are not "999". notice that each of the assertions is applied independently at the same point in the subject string. first there is a check that the previous three characters are all digits, then there is a check that the same three characters are not "999". this pattern does not match "foo" preceded by six characters, the first of which are digits and the last three of which are not "999". for example, it doesn't match "123abcfoo". a pattern to do that is (? =\d{3}...)(? !999)foo this time the first assertion looks at the preceding six characters, checking that the first three are digits, and then the second assertion checks that the preceding three characters are not "999". assertions can be nested in any combination. for example, (? =(? !foo)bar)baz matches an occurrence of "baz" that is preceded by "bar" which in turn is not preceded by "foo", while (? =\d{3}(?!999)...)foo is another pattern which matches "foo" preceded by three digits and any three characters that are not "999". assertion subpatterns are not capturing subpatterns, and may not be repeated, because it makes no sense to assert the same thing several times. if any kind of assertion contains capturing subpatterns within it, these are counted for the purposes of numbering the capturing subpatterns in the whole pattern. however, substring capturing is carried out only for positive assertions, because it does not make sense for negative assertions. assertions count towards the maximum of 200 parenthesized subpatterns.
lorsqu'un masque commence par.* et que l'option pcre_dotall est activée, le masque est implicitement ancré par pcre, étant donné qu 'il ne peut que rechercher au début de la chaîne.
