Modify TIFF Tags without Loading the Image
Tags can be modified without loading the image, using the ImageX.ReadAllMetaData and ImageX.SaveAllMetaData methods. (See Query Images).
Modify TIFF Tags in a Loaded Image
Once a TIFF image has been loaded into an ImageX object, the tags can be modified by accessing the tag collection associated with the ImageX object (Tags).

Please see the TIFF and EXIF file specification for more information about tags. |
Modify JPEG Comments
JPEG, JPEG2000, JLS, or WSQ files may have a list of comments. ImagXpress® enables you to modify comments of an image loaded into ImageX, as follows:
- Count the comments: The JPEGCommentCount property returns the number of comments contained in the file.
- Get the comment: The ReturnJpegComment method returns the text associated with a specified comment.
- Add a comment: The AddJpegComment method adds a comment to the comment list.
- Delete a comment: The DeleteJpegComment method deletes a comment from the comment list.
