+ + # Return Exif tags + tags = exifread.process_file(f) + +*Note:* To use this library in your project as a Git submodule, you should:: + + from import exifread + +Returned tags will be a dictionary mapping names of Exif tags to their +values in the file named by path_name. +You can process the tags as you wish. In particular, you can iterate through all the tags with:: + + for tag in tags.keys(): + if tag not in ('JPEGThumbnail', 'TIFFThumbnail', 'Filename', 'EXIF MakerNote'): + print "Key: %s, value %s" % (tag, tags[tag]) + +An ``if`` statement is used to avoid printing out a few of the tags that tend to be long or boring. + +The tags dictionary will include keys for all of the usual Exif tags, and will also include keys for +Makernotes used by some cameras, for which we have a good specification. + +Note that the dictionary keys are the IFD name followed by the tag name. For example:: + + 'EXIF DateTimeOriginal', 'Image Orientation', 'MakerNote FocusMode' + + +Tag Descriptions +**************** + +Tags are divided into these main categories: + +- ``Image``: information related to the main image (IFD0 of the Exif data). +- ``Thumbnail``: information related to the thumbnail image, if present (IFD1 of the Exif data). +- ``EXIF``: Exif information (sub-IFD). +- ``GPS``: GPS information (sub-IFD). +- ``Interoperability``: Interoperability information (sub-IFD). +- ``MakerNote``: Manufacturer specific information.

It either + has to return a string or markup object. +2. if an object has an ``__html__`` method it is called. +3. otherwise the default format system of Python kicks in and the result + is HTML escaped. + +Here is how you can implement your own formatting: + +.. code-block:: python + + class User(object): + + def __init__(self, id, username): + self.id = id + self.username = username + + def __html_format__(self, format_spec): + if format_spec == 'link': + return Markup('{1}').format( + self.id, + self.__html__(), + ) + elif format_spec: + raise ValueError('Invalid format spec') + return self.__html__() + + def __html__(self): + return Markup('{0}').format(self.username) + +And to format that user: + +.. code-block:: python + + >>> user = User(1, 'foo') + >>> Markup('

User: {0:link}').format(user) + Markup(u'

Logical Hebrew ?? +# +# Both "ISO" charsets use a completely identical set of code points, whereas +# "windows-1255" and "x-mac-hebrew" are two different proper supersets of +# these code points. windows-1255 defines additional characters in the range +# 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific +# diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6. +# x-mac-hebrew defines similar additional code points but with a different +# mapping. +# +# As far as an average Hebrew text with no diacritics is concerned, all four +# charsets are identical with respect to code points. Meaning that for the +# main Hebrew alphabet, all four map the same values to all 27 Hebrew letters +# (including final letters). +# +# The dominant difference between these charsets is their directionality. +# "Visual" directionality means that the text is ordered as if the renderer is +# not aware of a BIDI rendering algorithm. The renderer sees the text and +# draws it from left to right. The text itself when ordered naturally is read +# backwards. A buffer of Visual Hebrew generally looks like so: +# "[last word of first line spelled backwards] [whole line ordered backwards +# and spelled backwards] [first word of first line spelled backwards] +# [end of line] [last word of second line] ... etc' " +# adding punctuation marks, numbers and English text to visual text is +# naturally also "visual" and from left to right. +# +# "Logical" directionality means the text is ordered "naturally" according to +# the order it is read. It is the responsibility of the renderer to display +# the text from right to left. A BIDI algorithm is used to place general +# punctuation marks, numbers and English text in the text. +# +# Texts in x-mac-hebrew are almost impossible to find on the Internet. From +# what little evidence I could find, it seems that its general directionality +# is Logical. +# +# To sum up all of the above, the Hebrew probing mechanism knows about two +# charsets: +# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are +# backwards while line order is natural. For charset recognition purposes +# the line order is unimportant (In fact, for this implementation, even +# word order is unimportant). +# Logical Hebrew - "windows-1255" - normal, naturally ordered text. +# +# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be +# specifically identified. +# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew +# that contain special punctuation marks or diacritics is displayed with +# some unconverted characters showing as question marks. This problem might +# be corrected using another model prober for x-mac-hebrew. Due to the fact +# that x-mac-hebrew texts are so rare, writing another model prober isn't +# worth the effort and performance hit. +# +#### The Prober #### +# +# The prober is divided between two SBCharSetProbers and a HebrewProber, +# all of which are managed, created, fed data, inquired and deleted by the +# SBCSGroupProber. The two SBCharSetProbers identify that the text is in +# fact some kind of Hebrew, Logical or Visual. The final decision about which +# one is it is made by the HebrewProber by combining final-letter scores +# with the scores of the two SBCharSetProbers to produce a final answer. +# +# The SBCSGroupProber is responsible for stripping the original text of HTML +# tags, English characters, numbers, low-ASCII punctuation characters, spaces +# and new lines. It reduces any sequence of such characters to a single space. +# The buffer fed to each prober in the SBCS group prober is pure text in +# high-ASCII. +# The two SBCharSetProbers (model probers) share the same language model: +# Win1255Model. +# The first SBCharSetProber uses the model normally as any other +# SBCharSetProber does, to recognize windows-1255, upon which this model was +# built. The second SBCharSetProber is told to make the pair-of-letter +# lookup in the language model backwards. This in practice exactly simulates +# a visual Hebrew model using the windows-1255 logical Hebrew model. +# +# The HebrewProber is not using any language model. All it does is look for +# final-letter evidence suggesting the text is either logical Hebrew or visual +# Hebrew. Disjointed from the model probers, the results of the HebrewProber +# alone are meaningless. HebrewProber always returns 0.00 as confidence +# since it never identifies a charset by itself. Instead, the pointer to the +# HebrewProber is passed to the model probers as a helper "Name Prober". +# When the Group prober receives a positive identification from any prober, +# it asks for the name of the charset identified. If the prober queried is a +# Hebrew model prober, the model prober forwards the call to the +# HebrewProber to make the final decision. In the HebrewProber, the +# decision is made according to the final-letters scores maintained and Both +# model probers scores.

The application will work even with `__name__`, thanks + to how resources are looked up. However it will make debugging more + painful. Certain extensions can make assumptions based on the + import name of your application. For example the Flask-SQLAlchemy + extension will look for the code in your application that triggered + an SQL query in debug mode.
