For fade colour I just change the colour of the step's additive parts. The cis is then fed to the renderer and a faded image is produced.
It sounds like 'drawing outlines' will require significantly more processing to determine which edge lines will need to have it's colour manipulated.
What about this way? I think there is a pretty easy solution to that that does not require a lot of finding edges etc. let the renderer do it :-)
Render the first Step:
- LDView: All normal
Render the second Step:
- LDView: All normal
Render the second Step ONLY the additional parts:
- LDView: EDGES ONLY, THICKNESS = MAX
- change the color BLACK to a Highlight, e.g. YELLOW or ORANGE
Now merge the original STEP 2 and the Outlines of STEP 2
et voila! :-)
That should be fairly easily to do, the current "fade" feature detects the parts of a step in a similar way. As the control of LDView via the command line is pretty extensive this should be doable.
