HSLF's shape renderer supports only about 20 shapes out of 255 defined in the specification. At the moment only
relatively simple shapes are rendered OK (rectangle, triangle, diamond, etc.). More complex shapes such as arrows are
not supported and rendered as a filled bounding box.
However, it's possible to extend this part of HSLF and define new shapes. The outlines are defined in
org.apache.poi.hslf.model.AutoShapes:
http://svn.apache.org/repos/asf/poi/trunk/src/scratchpad/src/org/apache/poi/hslf/model/AutoShapes.java
You will need to edit this class and register new shapes outlines. Each shape is described in terms of
java.awt.GeneralPath - follow the pattern in the existing code.
AutoShapes are described in the Appendix D of OfficeDrawing97-2007BinaryFormatSpecification.pdf, the download link can
be found on http://poi.apache.org/guidelines.html.

Hi All!
Following http://poi.apache.org/slideshow/how-to-shapes.html#Render i can
export a slide into a image, but i obtain a poor quality imagem. More
complex shapes like arrows don't render, in your place appear a black filled
square. What can i do to export with a better quality?
