Michael Klink commented on PDFBOX-5851:
---------------------------------------
{quote}/P12 is a pattern. What's missing here is to set this to a pattern
colorspace. The PDF created by the CreatePatterns.java example looks like this:
{noformat}
50 500 200 200 re
/cs1 cs <==== this is missing
/p1 scn
f{noformat}{quote}
That code is invalid!
Between defining the path and painting it no **cs** or **scn** is allowed.
> When this PDF is rendered with the "f" Operator, a black screen appears.
