Zoltan Toth updated TIKA-1817:
------------------------------
Attachment: jcsample-screendump.jpg
jcsample.dxf
I have attached a sample DXF found on the web, as well as a screen dump taken
of the file being rendered by a freeware viewer called DWGSee
(http://www.autodwg.com/dwg-viewer/).
Hopefully, these will provide enough of an idea on what human readable text is
available i.e. It should be a simple matter of searching the sample DXF file
for rendered text content to discover how it is encoded.
Apologies, I should have done this at the beginning :-)
> Extracts entire file content for ASCII DXF files

>
> By definition, ASCII DXF files are encoded in plain text. However. the vast
> majority of their content is not intended to be human readable (see
> https://en.wikipedia.org/wiki/AutoCAD_DXF). Unfortunately for these files,
> Tika simply "extracts" the entire content of the file instead of the
> human-readable portions (i.e. comments etc.) that a CAD tool would render.
> This results in massive amounts of rubbish data being returned with dire
> consequences for applications that rely on this.
> It would be nice if only the human-readable text fields were extracted.
> Failing this, it would still be nice if no text was extracted from these
> files at all.
