Hi,

digital cameras add a lot of information into the JPEG files they generate.

This info is loaded into the Image object when executing Image.FromFile(filespec).
The info can be interrogated, item by item, by calling Image.GetPropertyItem(itemID).

AFAIK the info is preserved (not updated) when such image gets operated upon;
So as long as you modify and then save the Image to another file, you will still have
all the original properties, which may have become invalid, since they contain size,
datetime, etc, which may have been modified or become meaningless by the applied modifications.

When you create a new image from an existing one, as in new Bitmap(myImage),
the properties are not copied.

BTW you can add or modify properties using Image.SetPropertyItem().

Regards,


Luc Pattyn
