Editing Cartoon (section)

==Black and White Representation==
'''UPDATE''': This method is essentially obseleted by the new setting '''set ray_trace_mode,2'''.  More information on this at [[Ray]].
For those who want a nifty black and white representation of their protein try the following:
# Ray trace your protein of choice in a cartoon representation use a BLACK background
# Save the image
# Load the image in GIMP. [[Image:Bw1.jpeg|thumb|Black BG Ribbon|center|350px]]
# Desaturate or Grayscale the image. [[Image:Bw2.jpeg|thumb|Grayscale|center|350px]]
# Run the filter: Filter->Edge-Detect->Edge. [[Image:Bw3.jpeg|thumb|Edge Detect|center|350px]]
# Select: Layers->Color->Invert. [[Image:Bw4.jpeg|thumb|Invert Color|center|350px]]
# Different methods of edge detection will give you different results.  In the last example, I used Laplace Edge-Detect, then painted an all white layer beneath the current layer to achieve the results. [[Image:Bw5.jpeg|thumb|Other Styles|center|350px|Comments]]


I'm sure there are other ways to do this.  If you want to include it in a publication make sure you ray traced it large enough.  For that, see [[Publication_Quality_Images|Creating Publication Quality Images]].
