Re: [libredwg] Reed-Solomon patch.

[Felipe Castro]

Till, only after 2 months I'm having the time to get back looking at the code here, thanks for your suggestion, I'll take a look at those string offsets.


LibreDWG is put in the "featured resource" page of LibrePlanet, although it is not been updated for a long time. Some volunteer?

I would suggest that the string and handle chains are handled like in R2007. Have a look at the r2007 branch and if you are lucky not much has to be changed.

In R2010 and R2013 there are no need to use the Reed-Solomon algorithm, they are based closely to versions R2004, with some other stuff from R2007, but no fancy encoding. I think there's a post about these moves from AutoDesk here, but I don't remember where...

I was trying to decode R2010, but I have an issue, where to get the string chain for the header variables section. Anyone can help on this with more informtation?

I notice that Alex Papazoglou submitted a patch that expedites
Reed-Solomon encoding and decoding for DWG R2007 files.

Does this mean libredwg is now capable of reading these files? If so,
then the Libreplanet wiki needs to be updated.
http://libreplanet.org/wiki/Group:LibreDWG

That page also suggests that we don't have information for R2010 and
R2013 DWG formats, but I believe that the latest ODA document
describes these.

If I understand correctly, the changes between R2007 and R2010 are
quite minor, so does this give us the capability to read R2010 files?
And later?

Many thanks,

Dave
