How to get different silhouette widths for 2 maps
Hi there, I am trying to create a video with two maps overlay with different silhouette widths. It is easy to do with 2 images, but how I can do it in a video setting? If I change the width to 6, all maps changes the width to 6. Thanks! -Hong
Hi Hong, I don't think there is any way to do it directly in ChimeraX. There is only one global silhouettes state (on or off) and one silhouette width per running instance of ChimeraX. As far as I know: You'd have to do something really fancy like save the individual image frames for two separate movies (using the two different silhouette linewidths), then use some image editing program (e.g. in Gimp or whatever you've been doing already for 2 images) to combine the pair of images for each frame, and then some other method to assemble the time series of pairwise-combined images into a movie.

Hi Hong, Elaine is right that the silhouettes are calculated on the entire scene placing black edges where the depth jumps, so no way to apply different silhouette widths to different maps. But a trick you could use is to select one of the maps to show a green selection outline. The color and width of the selection outline can be set with command graphics selection color black width 6 The selection outline is different than a silhouette, it only goes around the perimeter of the map while a silhouette also highlights jumps in the middle of a single map. But maybe it will be what you need. Tom
