read TIFF tags

I'm new to C# , I use MS visual studio.NET 2003.
I have some TIFF images, I want to write a program using c# that reads an
image (.tiff) and prints all its tags. can anyone guid me to the right way?
Thanks

re: read TIFF tags

I've done this. It would require getting your hands on the Adobe Tiff file
byte order documentation. It's a big job, as TIFF files are quite
extensible. They can hold multiple images, store all sorts of meta data
about the images, and even store them in big-endian or little-endian byte
order. I believe there are some libraries around that can parse TIFFs as
well. I couldn't tell you how good any of them are.

re: read TIFF tags

First you need the TIFFspec...

http://partners.adobe.com/public/dev...iff/index.html

Then you open your image as a bitmap
Get the propertyitems and you can go from there...

System.Drawing.Bitmap newbit = new
System.Drawing.Bitmap("c:\\temp\\test.tif");

System.Drawing.Imaging.PropertyItem[] newprop;

newprop=newbit.PropertyItems;

Property Items seem to have a structure of...
Id - number value to match the tag id in the spec....
Len
Type
Value

and this matches what you can find in the spec....
