## Description

This structure embeds information in a JPEG file's Exif tag , which enables the image to be loaded by the DSi camera.

The `TCL_EncodeAndWritePicture(Ex)` function that is used when encoding embeds to the MakerNote internally, so there is no need to be directly concerned with this structure.

Sometimes it is necessary to evaluate the appropriateness of the decoded JPEG image. For more information, see the `TCL_IsSameImageType` function.

The direct use of any of its members from an application is prohibited.
