This is not a bug in dxfWriter, it was the original coloring in the Blender file...

New version online with experimental coloring from the rendered image.
Download dxfWriter 0.0.4

Note, the results from this are highly dependent on the blend file. Best results are achieved when the edges are inside the texture of the objects.
If the edges are at the outline, the result is mostly not so good...
Also the result varies at different sizes, I suggest 1024x1024.
This was a quick hack/test, so please report your results, maybe with attached .blend files... :-)

It adds the color from the rendered image directly to the points/lines inside the dxf file. So ILS SOS's recoloring isn't needed anymore...
And yes in the rendered images the color is from the freestyle module.

yes the bitmap images get the object color. if you need the original coloring also in the bitmap files, the only option is actuall to render twice.
one time with freestyle and one time without freestyle...

just change your directory for ren der output...

- change the render directory
- render with freestyle
- change the render directory again
- render without freestyle

in the first dir are the correctly colored dxf files and wrong bitmap files
in the second dir are the correct bitmpap files

just a workaround until the next release... ;-)

die you enable the rendered colors in the dxfWriter options?
maybe you didn`t update the dxfWriter GUI plugin?

@dream:
dxfWriter doesn't sort the lines, it just takes the edges from freestyle...

new version for Blender 2.70:

New in this version:
- support for Blender 2.70
- new color shader for getting the color from the rendered image (basically the same as in the last version, but displays the correct colors in the render window, instead of white)

Many thanks for this plugin !

It's the best thing I found so far to get vector output from Blender and import to Flash !

Two questions though :
- Can I get DXF output in an older DXF format ? (unlikely because you said you rewrote output to get R14 that supports true color)
- Straight lines are in fact made up from many segments. Is this because of the Freestyle rendering ?

Thanks again !

@magus:
it's great seeing use of this plugin! :-)

@pjgfi:
unfortunately, I'm using currently the R14 format as you said and I don't want to support R13 anymore. since the lack of true color support.
regarding lines, this depends on the original objects/meshes, my plugin just takes the Freestyle lines and puts them into the dxf file.
If I would use the chaining option from Freestyle I could combine them into one line again.
I think I will add this as option.
