On Debian I can convert png to eps files using convert:

hille@debian-amd64-sid:~$ ls -l replaceDialog.*
-rw-rw-r-- 1 hille hille 26755 May  7  2015 replaceDialog.png
hille@debian-amd64-sid:~$ convert replaceDialog.png replaceDialog.eps
hille@debian-amd64-sid:~$ ls -l replaceDialog.*
-rw-r--r-- 1 hille hille 774464 Apr  9 23:04 replaceDialog.eps
-rw-rw-r-- 1 hille hille  26755 May  7  2015 replaceDialog.png

Doing the same on Ubuntu 20.10 fails:

ubuntu@ubuntu2010:~$ convert replaceDialog.png replaceDialog.eps
convert-im6.q16: attempt to perform an operation not allowed by the 
security policy `EPS' @ error/constitute.c/IsCoderAuthorized/408.

b/c the /etc/ImageMagick-6/policy.xml differs between Debian & Ubuntu.

The Makefile has a fallback to netpbm, but this does not work as we do 
not declare a B-D on netpbm. We could simply add it.

What do you think?
