Reserve more place for tag modifications #43

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
It is not a bug, it is more an evolution.

I can't see in your code if you have reserved more place than necessary to 
store all the tag values.

My idea is to avoid to rewrite all the file every time I modify some tag 
values. 

In my application, I can add comment, author and GPS tag, and if I want to 
modify my comment or author, I thought it could be a good idea to have some 
place to modify this tags and not to rewrite all the image file. 
The first time, I need more place, the library allocates more place than 
necessary about 50 or 100 bytes and after, it is necessary to rewrite only the 
IFD to update the new tag values.

Do you think the EXIF format permit this evolution ? And if yes, do you think 
your implementation can do it ?

Thank you in advance.
