I see that ImageFormat includes exif.

But I can't find out if

I've System.Drawing.Image.FromStream

or something like it

can read and/or write that format.



I'm familiar with Q316563 but it does not mention exif



Thanks in advance

The MSDN site has information that may help you here:
http://msdn2.microsoft.com/en-us/library/xddt0dz7.aspx

Since gdiplus is old (i.e., the only version ever released was version 1.0),
it does not support all of the EXIF image tags.

A more robust solution is to use the COM Interfaces IStorage,
IPropertySetStorage, etc.

These interfaces will allow you to read and write all EXIF image tags, as
well as, all metadata for video, music, compound documents, etc.

See the MSDN online site for details. There ares no .Net classes or methods
implemented. You must implement these interfaces yourself.

In Dotnet there is an ImageFormat.Exif Property.

What is that for?

Thanks

It just lets you know that EXIF metadata is present.

It does NOT relate to a file extension - like maybe- *.EXIF
True?

You could always just try it and see if it works.

Try what?
I wanted to try to read such a file but searched my entire disk and couldn't
find one.
I'll look at the sites now.

Thanks

I checked the sites but they had the same info as my VS help. As I said in
my post, I knew it was an image format property. All the other properties
relate to file extensions.

What I don't know is if exif also relates to an extension.


Does it?

Thanks

Here's the first link from googling "exif files".

http://park2.wakwak.com/~tsuruzoh/Co...ms/exif-e.html

which leads to this:

http://www.leadtools.com/SDK/Raster/...ormat-EXIF.htm

which says their tool "reads and writes the following Exit format: TIFF and
JPG."

Here's the next link which talks about a Jpeg Header and Thumbnail
Manipulator Program, and lists things they can extract from an Exif jpeg
file.

http://www.sentex.net/~mwandel/jhead/

Google is your friend.

So try opening a jpeg and check the ImageFormat.exif property and see if
it's true, and if so, the exif metadata is present, that would be my guess.

at those sties I see things like: Exif Formats (TIFF and JPG) and so I keep
asking the same question:
Is exif a file extension or something that relates to files with other
extensions.

Is it used as a file extension yes or no?


As far as using Google, I get so many hits I must have looked at a hundred
sites but never there nor here found out the answer to my question.

I did find some great info about extracting exif data that I had no idea
some files have.


thanks for trying to help
