Hi Daniel,
How would you compare the WMF and EMF formats to Escher Drawing layer
objects included in an XLS or PPT?
This is a question about the format.
Java2D can read only JPEG and PNG, that is we parse a ppt file,
read a
JPEG and pass it to the target Java2D object. But how to convert WMF
or PICT into java.awt.Image?
PICT I'm not sure about -- if there is a project out there which
can render
it, I'd love to know.
Apple supports PICT with QuickTime. And they have a Java API. So,
it's a solution for MacOSX or Windows, but not necessarily for Linux.
Batik has a renderer for WMF, so that isn't an issue.
The FreeHEP project has a renderer for EMF, so that isn't an issue
either.
A renderer is not the same as an interpreter. Knowing Yegor, I am
sure he was describing the problem of interpreting any "random" valid
PPT file including interpreting any included graphic object. While
you are describing the solution of rendering a file. A point to keep
in mind, renderers may be limited to producing their own particular
flavor of a validly formatted file. They won't necessarily implement
every feature of the file format. Keep this in mind when using POI.
I think that you can categorize POI users along two axes:
(1) Interpreter and/or Renderer.
(2) File Format. HSSF (XLS), HSLF (PPT), HWPF (DOC) and the
beginnings of HDGF (VSD/Visio) format investigation just today by Nick.
POI seems to grow as developers appear to fill out the features in
these "cells" to the extent of their time, interest and ability.
Regards,
Dave Fisher
Daniel
