Subject: [iText-questions] re:
com.lowagie.text.pdf.PdfContentByte.clip()
Hello
all!
In my
project I need to make iText & JFreeChart APIs to work on UNIX
running without graphical subsystem. iText works well, however JFreeChart
requires java.awt.Graphics2D and java.awt.Font classes which in turn require X
environment. To overcome this limitation I introduced my own implementation of
Graphics class which relies on com.lowagie.text.pdf.PdfContentByte
methods. Then I went through all classes of JFreeChart and changed references
to Graphics2D on references to my class. Also I changed java.awt.Font on
com.lowagie.text.Font. After two days of working it all started working as I
expected. However there are few things that need to be
fixed.
It was
pretty easy to implement such methods as fill(), draw() and drawText(). Now I
am stack with implementation of clip(), getClip() and setClip() methods.
PdfContentByte class features method clip. Below is the API
documentation on this method:
Modify the current
clipping path by intersecting it with the current path, using the nonzero
winding number rule to determine which regions lie inside the clipping
path.
It is not clear what
the clipping path is and how I can manage it. According to the documentation
iText deals with two paths: clipping path and current path.
PdfContentByte's methods like lineTo affect current path. How I set and get
the state of clipping path? Are there any examples of using clip
method?
Thank you very much! Any help will be greatly
appreciated.
