extern KADMOS_ERROR KADMOS_API rel_freeimages(RelData *reldata);
reldatarel_do() initialized structure RelData.RE_SUCCESS or KADMOS error type.
If rel_do() had been called with TYPO_KEEPIMG then all images of the segmented single
characters are stored and available after the call. A call of rel_freeimages() frees this memory.
In case of success the function returns RE_SUCCESS, in case of error it returns the related error type.
The error text can be retrieved by calling re_GetErrorText() or be displayed by calling re_DisplayErrorText().
