Conversion of AFX format (Auto/FX) to any other image format seems to be not possible. However, you may be able to print it to PDF using a virtual PDF printer installed.
We have been informed by Auto F/X representatives, that using a 3rd party conversion program in order to convert .afx images to something else (like .jpg), would be a violation of user agreements of Auto F/X products and may result in the software being deactivated. Users are not allowed to alter file structure Auto F/X software and some converters can trigger the deactivation.Open AFX file Open PDF file
