Hi,
I had the same problem. The paint methods from Swing components often use
SwingGraphics.createSwingGraphics(g) to create a new graphic context
derived from the existing context. This results in a call PDFGraphics2D.create
() which returns a new PDFGraphics2D object. The new object owns a duplicate
from the underlying PDFContentByte instance. And in my opinion the newly
created PDFContentByte instance has no affect for the pdf document. I solved
the problem
with a few changes. I don't know exactly, if its correct but it works fine
for us.
Changes in PDFGraphics2D.create():
Old:
g2.cb = this.cb.getDuplicate();
New:
g2.cb = this.cb;
And:
Old:
g2.kid = true;
synchronized (kids) {
kids.add(g2);
}
New:
g2.kid = false;
