iPhone 3G Digital Image

6 posts in this topic

#1 ·  Posted (edited)

This code reads and displays the extended properties of a digital image [date taken resolution that sort of thing].

;Read an image file

#include <extprop.au3>

#include <array.au3>

$path = FileOpenDialog("Select a file to read attributes",@ScriptDir,"All (*.*)")

$prop = _GetExtProperty($path,-1)

_ArrayDisplay($prop,"Property Array")

With a iPhone 3G Camera photos are tagged with location data if Location Services is turned on. You can use location data with some applications and photo-sharing websites to track and post where you took your pictures.

For some reason the above code does not display the tagged location information. Why is that so?

Edit:

In Windows Photo Gallery when you select the image and display the properties under 'GPS' the Latitude and Longitude information is displayed which is the information I would like to be able to read using AutoIT.

Ant.. :)

I think it would help a lot if you would post a link to extprop.au3 or the au3 file itself. We can't help you if we don't have that information.

Now send me an iPhone to test and I'll help you out :). Sorry, had to. I don't have one nor do I have a picture taken with one so I can't really test. My guess is that the location data is stored somewhere the function isn't looking, such as in the header of the image.

The location info should be in a Exif-tag, i don't think there are any udf to read that currently, but a good place to start would be Lazycats udf for reading exif info
