<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>

<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>
