- This page is in the table of contents.
- Vectorwrite is a script to write Scalable Vector Graphics for a gcode file.
- The vectorwrite manual page is at:
- http://www.bitsfrombytes.com/wiki/index.php?title=Skeinforge_Vectorwrite
- Vectorwrite generates a Scalable Vector Graphics file which can be opened by an SVG viewer or an SVG capable browser like Mozilla:
- http://www.mozilla.com/firefox/
- ==Operation==
- The default 'Activate Vectorwrite' checkbox is on. When it is on, the functions described below will work when called from the skeinforge toolchain, when it is off, the functions will not be called from the toolchain. The functions will still be called, whether or not the 'Activate Vectorwrite' checkbox is on, when vectorwrite is run directly.
- ==Settings==
- ===Layers===
- ====Layers From====
- Default is zero.
- The "Layers From" is the index of the bottom layer that will be displayed. If the layer from is the default zero, the display will start from the lowest layer. If the the layer from index is negative, then the display will start from the layer from index below the top layer.
- ====Layers To====
- Default is a huge number, which will be limited to the highest index layer.
- The "Layers To" is the index of the top layer that will be displayed. If the layer to index is a huge number like the default, the display will go to the top of the model, at least until we model habitats:) If the layer to index is negative, then the display will go to the layer to index below the top layer. The layer from until layer to index is a python slice.
- ===SVG Viewer===
- Default is webbrowser.
- If the 'SVG Viewer' is set to the default 'webbrowser', the scalable vector graphics file will be sent to the default browser to be opened. If the 'SVG Viewer' is set to a program name, the scalable vector graphics file will be sent to that program to be opened.
- ==Examples==
- Below are examples of vectorwrite being used. These examples are run in a terminal in the folder which contains Screw Holder_penultimate.gcode and vectorwrite.py.
- > python vectorwrite.py
- This brings up the vectorwrite dialog.
- > python vectorwrite.py Screw Holder_penultimate.gcode
- The vectorwrite file is saved as Screw_Holder_penultimate_vectorwrite.svg
- > python
- Python 2.5.1 (r251:54863, Sep 22 2007, 01:43:31)
- [GCC 4.2.1 (SUSE Linux)] on linux2
- Type "help", "copyright", "credits" or "license" for more information.
- >>> import vectorwrite
- >>> vectorwrite.main()
- This brings up the vectorwrite dialog.
- >>> vectorwrite.getWindowAnalyzeFile('Screw Holder_penultimate.gcode')
- The vectorwrite file is saved as Screw_Holder_penultimate_vectorwrite.svg
