Modify TIFF Tags in a Loaded Image

Once a TIFF image has been loaded into ImagXpress®, the tags can be modified by accessing the "Tag" properties and methods within the ImagXpress object.

Tags can be also modified without loading the image, using the FileGetTags and FileSetTags methods. (See Query Image Files).

Modify JPEG Comments in a Loaded Image

JPEG, JPEG2000, JLS, or WSQ files may have a list of comments. ImagXpress enables you to modify comments of an image loaded into ImagXpress, as follows:

Count the comments: The JPEGCommentCount property returns the number of comments contained in the file.
Get the Comments: The JPEGGetComment method returns the text associated with a specified comment.
Add a Comment: The JPEGCommentAdd method adds a comment to the comment list.
Delete a Comment: The JPEGCommentDelete method deletes a comment from the comment list.

The Undo method does not undo changes to JPEG comments or TIFF tags.
