How can I generate Ean18 code to SVG with separator?

[kyuranger]

I want to generate Ean18 to SVG like this:

As you see, the code has a lead, separator and trailer.

This question is similar like #452

However, the solution above using some package only works in Windows and currently I need to run in Linux/MAC/Android/IOS for cross platform.

In addition, that way seems cannot generate to SVG format also.

How can I solve this?

You have to write your own renderer class (similar to AlternateBitmapRenderer).
