This section describes each mark available in ImageGear ART component, and its associated attributes.
Some ART marks, such as Attach-a-Note, Text Stamp, and Typed Text, may require Wang compatibility mode enabled to be saved properly. On the contrary, the Highlighter mark should be saved without Wang compatibility mode on. |
Wang/Kodak viewer included with Windows would only understand Wang-compatible annotations. |
These constants define a range of user marks reserved for customer use. ImageGear will never use this range of the mark IDs for its purposes. |
