+ <title>Overview</title>
+
+ <p>HDGF is the POI Project's pure Java implementation of the Visio file format.</p>
+ <p>Currently, HDGF provides a low-level, read-only api for
+ accessing Visio documents. It also provides a
+ <link href="http://svn.apache.org/repos/asf/poi/trunk/src/scratchpad/src/org/apache/poi/hdgf/extractor/">way</link>
+ to extract the textual content from a file.
+ </p>
+ <p>At this time, there is no <em>usermodel</em> api or similar,
+ only low level access to the streams, chunks and chunk commands.
+ Users are advised to check the unit tests to see how everything
+ works. They are also well advised to read the documentation
+ supplied with
+ <link href="http://www.gnome.ru/projects/vsdump_en.html">vsdump</link>
+ to get a feel for how Visio files are structured.</p>
+ <p>To get a feel for the contents of a file, and to track down
+ where data of interest is stored, HDGF comes with
+ <link href="http://svn.apache.org/repos/asf/poi/trunk/src/scratchpad/src/org/apache/poi/hdgf/dev/">VSDDumper</link>
+ to print out the contents of the file. Users should also make
+ use of
+ <link href="http://www.gnome.ru/projects/vsdump_en.html">vsdump</link>
+ to probe the structure of files.</p>
+ <note>
+ This code currently lives the
+ <link href="http://svn.apache.org/viewcvs.cgi/poi/trunk/src/scratchpad/">scratchpad area</link>
+ of the POI SVN repository.
+ Ensure that you have the scratchpad jar or the scratchpad
+ build area in your
+ classpath before experimenting with this code.

+ <title>Steps required for write support</title>
+ <p>Currently, HDGF is only able to read visio files, it is
+ not able to write them back out again. We believe the
+ following are the steps that would need to be taken to
+ implement it.</p>
+ <ol>
+ <li>Re-write the decompression support in LZW4HDGF to be
+ less opaque, and also under the ASL.</li>
+ <li>Add compression support to the new LZw4HDGF.</li>
+ <li>Have HDGF just write back the raw bytes it read in, and
+ have a test to ensure the file is un-changed.</li>
+ <li>Have HDGF generate the bytes to write out from the
+ Stream stores, using the compressed data as appropriate,
+ without re-compressing. Plus test to ensure file is
+ un-changed.</li>
+ <li>Have HDGF generate the bytes to write out from the
+ Stream stores, re-compressing any streams that were
+ decompressed. Plus test to ensure file is un-changed.</li>
+ <li>Have HDGF re-generate the offsets in pointers for the
+ locations of the streams. Plus test to ensure file is
+ un-changed.</li>
+ <li>Have HDGF re-generate the bytes for all the chunks, from
+ the chunk commands. Tests to ensure the chunks are
+ serialized properly, and then that the file is un-changed</li>
+ <li>Alter the data of one command, but keep it the same
+ length, and check visio can open the file when written
+ out.</li>
+ <li>Alter the data of one command, to a new length, and
+ check that visio can open the file when written out.</li>
+ </ol>
