    Jpg EXIF decoding and Jpg barcode reading

    Howdy Y'all!

    My boss has asked me to do something difficult and audit all the compay's assets )

    It is my feeling that a lot of our existing process can be automated and I had an idea to use my ipod's camera, geotagging and try to find routines to extract the barcodes already on the assets on a server.

    * I would like to learn how to decode a jpg's meta data and determine the location lat/long and alt and date of the picture by exif using c code.

    * I would also like to know how to read a barcode and/or numeric serial number (asset code) from the same picture also in c.

    Any links to useful c, c++ (console) routines would be much appreciated.

    Happy holidays everybody!

    Yes, you can put each of your search terms into google and do your own reading, for your own job.

    We're on holiday too - enjoy!

    If at first you don't succeed, try writing your phone number on the exam paper.

    Hi,
    Thanks for your post.
    I have extensively downloaded examples from code project and researched exim.org but lack the skills to understand.
    If you don't want to help that's fine but don't use your post to discourage others.
    Thanks!

    He's not discouraging you from trying the project, he's discouraging you from running for help at the first sight of difficulty.

    If you're having trouble understanding, it often helps to break it up, follow the flow of the program, and then google specific syntax that you don't know.

    Really....

    Strange that you didn't actually post any code to demonstrate what you did learn.

    > If you don't want to help that's fine but don't use your post to discourage others.
    If 1 reply discourages you, then software development isn't for you. Try chasing random bugs in complex systems for a few weeks, if you want to really understand how frustrating life can get.

    > My boss has asked me to do something difficult
    So go ask for some training.

    Or confess that you got the job on false pretences. It wouldn't be the first time that someone clueless about their job rolled through looking for help to save their ass.

    Students trying to leech free homework are bad enough, but when people who claim to be employed show up without showing a decent amount of effort, well that takes the biscuit.

    We do all the work for $0, and you get all the credit and $$$ for a job well done.

    Goto vWorker.com if you don't want to learn, and are willing to exchange part of your paycheck for someone else to do the work for you.

    So you might be able to ask a direct question that deserves a direct answer, as opposed to some zen "make me one with everything" ramble with no direction or end in sight.
