EXIF support

Heres a list of all the metadata tags my code understands. (Really it's a list of the tags that .Net understands, my code just knows how to find the fields that exist, extract the data and make it user-friendly).

I think the one you want to see is ExifUserComment. How do you set that? My camera doesn't put anything there automatically (nor should it), I'm guessing you use a 3rd party program like ACDSee?

Remember, only a small portion of these fields are going to be supported by your camera. Fields that are not written to the image do not appear when using the afformentioned foreach loop I showed before.

Also, those are the code field names. I have "pretty" display names for each one of those fields. They're hard-coded in my classes right now, but I will move them out to a resource table. They'll all be there in English, but someone would need to translate the resource table to other languages supported by MediaPortal. The translation of a resource table isn't hard, it's all XML. Anyone want to offer? Don't worry though, if a field isn't translated it will just be displayed with the default resource entry (which will be English).

Hi,

yes - to set the comment u need a 3rd party app (i.e. acdsee, paintshop, jalbum).
I could do translations to german.

I could do translations to german

Thanks ralf, PM me with an e-mail address and I'll e-mail you the resx file when it's ready to be translated.

Alright guys, I'm trying to move forward on this. I spent some time tonight and have the code mostly ready. I also got the string descriptions out to a resource table, but I'm not quite yet ready to have someone translate. Here's why:

When I started this project I was able to obtain a list of well-known meta tags, which makes up the list you saw a few posts ago. Using ACDSee and some online research I have done my best to come up with descriptive terms for the fields you saw. The descriptions I came up with are what is now in the resource table. However, some of the field names were just a little to cryptic for me to come up with good names for them. The field "T6Option", for example, has been described literally as "T6 Option".

I have posted the resource table up on SolerSoft at the following URL:

http://www.SolerSoft.com/MediaPortal/ImageProperty.zip

Before anyone begins translating it into another language, I'd like some image saavy people to look at this resource table and see if they can fix any of my lacking descriptions. Any and all help is appreciated.

The file within the zip file has the .resx extension. .resx is just a different file extension for XML, so you may safely change the file extension to XML and use your favorite editor if you don't have Visual Studio.

Thanks in advance to anyone that helps.

Regards,

eXe

Don´t know if I understood your problem completely, but I found an official description of EXIF Version 2.2. from the JEITA on the Kodak web-site.

You´ll find descriptions of the fields in words and parameters.

Look at this PDF:

http://www.kodak.com/global/plugins/...fStandard2.pdf

could not find T4Option or T6Option, though.

Thank you TomTom for that document. It is helping me improve my library quite a bit. I'll have to work on this more Wednesday evening (I hope) and then we'll have something to translate.

Also, I think the code's mostly ready, so we could start talking about how to include it.

if you need any help then dont be afraid 2 ask;-)
when i'm awake I'm on IRC efnet #Mediaportal

Hey guys, just wanted to let you know I havn't given up on this yet. Frodo gave me all the information I need to integrate it, I just haven't had time. I'll be on vacation this weekend but maybe I can have something next week?

I'm not trying to make excuses, but my company has been keeping me extra busy due to a customer conference in July. I'm not going to try and wait till thats over to get this done, but I will have a lot more time after that.

[tomtom21000]

The job comes first.
Take your time.

Hi eXentric, I am just curious if you are still around and interested.

I guess your code won´t make it into version 0.1 for sptember, first. But anyway, do you still plan to work on this? If not, do you mind passing your "almost ready code" to the project? Maybe someone else can take a look at the integration, if you are still under pressure with your job?
