Introducing JpgMetadataReader.cfc V0.3

another update so soon you ask?

The main difference with this version is I removed the getter and setter functions for ITPC metadata and created the functions:

- getMetadataKeys( type ) - setMetadataKeys( type , keys )

Why did I do this?

Because every digital camera stores some type of it's own meta data. To get access to this you can call:

<cfset stMetaData   = oMetaData.getMetaDataStruct("C:\path\to\jpg\picture.jpg","FujiFilm Makernote")>
...no prizes for guessing the make of digital camera I have!...

So what you can do is set the default keys (to empty string) like this:

<cfset oMetaData.setMetadataKeys("FujiFilm Makernote","valueone,valuetwo,valuethree")>

That way you don't need to worry about lots of "structKeyExists" calls! :-)

Hope this makes sense, and any feed back will be welcomed!
