Dxf2svg in Inkscape

Dxf2svg in Inkscape

The source code is at: 

Src/extension/dxf2svg

It needs .inx files, which are needed for the kml2svg work. 

The dxf_import.inx is at ../Inkscape/share/extensions

**************Quoted Readme of Dxf2svg*****************

Readme

1.  Run make and copy dxf2svg to somewhere that is looked at by the PATH variable.  Or add the current directory to your path

2.  Copy the dxf_import.inx to ../Inkscape/share/extensions

3.  Run Inkscape

4.  Click on open or import and the dxf option should be there

KML import thoughts

Recently, I am doing code review in Inkscape and experimenting transformations for converting KML polygon path to SVG. I have studied KML and SVG files further. I made several simple KML test files to try and see the conversion process. 

My first goal is to import a simple KML file and convert it to SVG.

I am thinking to do importing a simple KML file and converting it to SVG. In Inkscape, it seems complex. I am trying to find out: 

1. How to implement kml2svg in Inkscape, or kml import, similar to other file format import.
2. How transformations from kml to svg is done, and what rules they have. I may need to define many things, such as canvas, origin, anchor of objects/paths, dimensions and so on. 
3. What libraries are needed. 

I have reviewed Inkscape code base and the Java KML conversion program. I should be able to write the Java program in C++. I need to write kml-import, and thought good examples in Inkscape should be available. 

A question: 

Does anyone know kml-import is similar to which file format import? I have seen dxf2svg as an good example. But kml2svg starts with importing an XML file...

Online kml2svg convertor

I have tried and used the kml2svg converter: 

http://kml2svg.free.fr/index.php

This tool is a testing version only. It is useful to try things but is not complete with limitations. 

Its Mercator projection was discussed in:

KML to SVG

This tool converts google earth files(kml and kmz) into vectorial SVG files,
usable in Inkscape, Illustrator and other software.

kml2svg.free.fr converts most of the elements that contains a GE document:

• folders
• placemarks (points, lines, polygones, multigeometries and embeded images)
• tours
• Sketchup ressources (depending of the ressources..)

using the desired earth projection:

• Mercator,
• Miller,
• Cylindrical Equal-Area (Lambert, Behrmann, Tristan Edwards, Peters, Galls, Balthasart),
• Cylindrical Equidistant,
• Sinusoidal,
• Van der Grinten I,
• Polyconic,
• Albers Equal-Area Conic,
• Conic Equidistant,
• Bonne,
• Lambert Conformal Conic,
• Lambert Azimuthal Equal-Area,
• Cassini

SVG to KML

Conversion restrictions :

• It possible to convert only file originally converted by kml2svg, otherwise it is impossible to positionate correctly the draw on the earth surface.
• I recommand the use of INKSCAPE software to edit SVG file befor re-import.
• Only works with MERCATOR projection at this time
• The KML/KMZ format is mor restrictive than SVG, only few objects can be converted :
  • Text is converted in placemark
  • Lines are converted into paths.
  • Polygons and rectangles are converted into polygons
  • Groups and layers are converted into folders
  • Dash & dot lines are converted into plain line
