The documentation is far from complete.
I want to add a dashed line for instance.
So, that must be a gfx according to the page module. But there is no gfx module, the line feature is hidden in Content.
Content gives me this information about a dashed line:
So, what is the array supposed to be filled with?
And so I can make a very long list with examples.
This is a sad, very sad, because the module looks like it has a million features and is a ideal solution to write a PDF.
Please stop the development and invest time in documentation.
