- * type is a unique integer ID for this image type.
- *
- * Check() checks file descriptor fd. If file is recognized,
- * sets ids->xsize, ids->ysize, ids->zsize, and ids->subType, and returns TRUE.
- *
- * Iconify() opens ids->name, and creates an ABGR icon, ids->ixsize by
- * ids->iysize by 32 bits deep centered in the int bitmap[ICONSIZE][ICONSIZE]
- * array. Returns FALSE on any error.
- *
- * Info() uses the contents of ids->subType to create a description
- * string in buf. A pointer to the string is returned.
- *
- * Open() performs the action associated with a double-click on the
- * icon, usually firing up a viewer.
- *
- * To add support for a new image type, create versions of each of these
- * routines, then add their names to the ImageFn array in ibrowse.c along
- * with a unique integer image type identifier.
