I need to SAVE AND REOPEN an image with ImageEn with the following features:
1. Layers preserved: This works well with the .IEN format.
2. Custom marker (metadata?): I need to store a custom marker (e.g., MY_CUSTOM_MARKER) in the file so that when reopening the file, I can take a custom action accordingly.
3. Short meta text for each Layer: When reopening the image and clicking on a Layer, I need to retrieve the meta text stored in that Layer.
Which image formats support all these features in ImageEn natively?
Instead of using a custom marker, I have decided to create my own image file format - TIEFileFormatInfo makes it easy. Can I still save and reopen Layers in my custom File Format?
UPDATE: The UserDataInLayer demo is a nice example of storing user data in Layers. Thank you, ImageEn!
