Stefan Ziegler commented on PDFBOX-4975:
----------------------------------------
I would also need a non-Final PDPageContentStream. My file transformer class
uses PDPageContentStream.appendRawCommands for some font related
transformations because showText(String text) can not be be used here.
appendRawCommands methods are marked as @deprecated. So, we either need the
appendRawCommands methods or we need a non-final PDPageContentStream so that we
can extend PDPageContentStream.

> Currently {{PDPageContentStream}} is final.
> There are some situations where it would be useful to define our own
> {{PDPageContentStream}}.
> For example, in my use-case I want to be able to try multiple fonts in case
> the characters in the text are not all in one font. The library I'm using
> accepts {{PDPageContentStream}} instances, so it would be much easier to pass
> a subclass of {{PDPageContentStream}} with the desired behavior rather than
> overhaul the library itself.
