Hello,
I still have trouble printing (or painting) any Swing-Component
into an IText-Graphics2d!
Below you find a simple "main" that creates a Graphics2D
from an IText-Template and paints a simple JLabel into this
graphics.
The result is a corrupt PDF-Document that Acrobat-Reader
does not open.
The stdout-output of my program shows what the JLabel does
on the graphics:
Graphics(0-1) Enabling debug
Graphics(0-1) Setting color: java.awt.Color[r=0,g=0,b=0]
Graphics(0-1) Setting font:
java.awt.Font[family=Arial,name=Arial,style=plain,size=18]
Graphics(2-1) Setting color: java.awt.Color[r=0,g=0,b=0]
Graphics(2-1) Drawing string: "Hello" at: java.awt.Point[x=241,y=389]
If I do the same myself on the graphics, I get a fine PDF-document!
(see "main2" below).
So can anybody tell my, what the Component (here JLabel, but I've got the same
problem with any Swing-Component!) does on the graphics and what to do to get
an intact PDF-file???
Thanks a lot for any advice!
Lars
