+ POI-HDGF - Java API To Access Microsoft Visio Format Files + Overview + + + +
+ + +
+ Overview + +

HDGF is the POI Project's pure Java implementation of the Visio file format.

+

Currently, HDGF provides a low-level, read-only api for + accessing Visio documents. It also provides a + way + to extract the textual content from a file. +

+

At this time, there is no usermodel 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 + vsdump + to get a feel for how Visio files are structured.

+

To get a feel for the contents of a file, and to track down + where data of interest is stored, HDGF comes with + VSDDumper + to print out the contents of the file. Users should also make + use of + vsdump + to probe the structure of files.

+ + This code currently lives the + scratchpad area + 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. + + +
+ Steps required for write support +

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.

+
    +
  1. Re-write the decompression support in LZW4HDGF to be + less opaque, and also under the ASL.
    2. +
  2. Add compression support to the new LZw4HDGF.
    3. +
  3. Have HDGF just write back the raw bytes it read in, and + have a test to ensure the file is un-changed.
    4. +
  4. 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.
    5. +
  5. 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.
    6. +
  6. Have HDGF re-generate the offsets in pointers for the + locations of the streams. Plus test to ensure file is + un-changed.
    7. +
  7. 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
    8. +
  8. Alter the data of one command, but keep it the same + length, and check visio can open the file when written + out.
    9. +
  9. Alter the data of one command, to a new length, and + check that visio can open the file when written out.
