exif(n) EXIF parsing exif(n) NAME
exif - Tcl EXIF extracts and parses EXIF fields from digital images SYNOPSIS
package require Tcl 8.2 package require exif ?1.0? exif::analyze channel exif::fieldnames DESCRIPTION
The EXIF package is a recoding of Chris Breeze's Perl package to do the same thing. This version accepts a channel as input and returns a serialized array with all the recognised fields parsed out. There is also a function to obtain a list of all possible field names that might be present, which is useful in building GUIs that present such information. COMMANDS
exif::analyze channel channel should be an open file handle rewound to the start. It does not need to be seekable. channel will be set to binary mode and is left wherever it happens to stop being parsed, usually at the end of the file or the start of the image data. You must open and close the stream yourself. If no error is thrown, the return value is a serialized array with informative English text about what was found in the EXIF block. Failure during parsing or I/O throw errors. exif::fieldnames This returns a list of all possible field names. That is, the array returned by exif::analyze will not contain keys that are not listed in the return from exif::fieldnames. Of course, if information is missing in the image file, exif::analyze may not return all the fields listed in the return from exif::fieldnames. This function is expected to be primarily useful for building GUIs to display results. N.B.: Read the implementation of exif::fieldnames before modifying the implementation of exif::analyze.

CREEPY - A geolocation information aggregator DESCRIPTION
creepy is an application that allows you to gather geolocation related information about users from social networking platforms and image hosting services. The information is presented in a map inside the application where all the retrieved data is shown accompanied with rele- vant information (i.e. what was posted from that specific location) to provide context to the presentation. FEATURES
Map providers available : Google Maps - Virtual Maps - Open Street Maps Location information retieval from : Twitter's tweet location: Coordinates when tweet was posted from mobile device. Place (geographical name) derived from users ip when posting on twitter's web interface. Place gets translated into coordinates using geonames.com" Bounding Box derived from users ip when posting on twitter's web interface.The less accurate source , a corner of the bounding box is selected randomly. Geolocation information accessible through image hosting services API EXIF tags from the photos posted. Social networking platforms currently supported: Twitter Foursquare (only checkins that are posted to twitter). Image hosting services currently supported : flickr - information retrieved from API twitpic.com - information retrieved from API and photo exif tags yfrog.com - information retrieved from photo exif tags img.ly - information retrieved from photo exif tags plixi.com - information retrieved from photo exif tags twitrpix.com - information retrieved from photo exif tags foleext.com - information retrieved from photo exif tags shozu.com - information retrieved from photo exif tags pickhur.com - information retrieved from photo exif tags moby.to - information retrieved from API and photo exif tags twitsnaps.com - information retrieved from photo exif tags twitgoo.com - information retrieved from photo exif tags NOTES
Automatic caching of retrieved information in order to reduce API calls and the possibility of hitting limit rates. GUI with navigable map for better overview of the accumulated information 4 Maps providers (including Google Maps) to use. Open locations in Google Maps in your browser Export retrieved locations list as kmz (for Google Earth) or csv files. Handling twitter authentication in an easy way using oAuth. User credentials are not shared with the application. User/target search for twitter and flickr. AUTHOR
