[Insight-developers] SpatialObjectToImage questions

[Julien Jomier]

Hi Richard,

One way to do it, is to modify the ValueAt() function for a 
LandmarkSpatialObject so it returns the grayscale value of the RGB 
color. Would that work for you?. So basically you set the color of your 
landmarks and the SpatialObjectToImageFilter will use the grayscale 
value of the color.

There is no way to modify the way the landmark are displayed and there 
is no easy way to do it other than writing your own code.

Let me know,

Julien
