  Re: What does a subpart with color=24 mean?
 
(...) It will be the constrast color for the constrast color. Which may be the same as the main color -- but it may not. Also, some viewers (like L3Lab) may balk at rendering a file which uses color 24 in a line type 1. Steve (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
(...) Does that mean that it would be appropriate for a renderer to just swap the main and contrast colors when it encounters such a line, or what? I just want know what a renderer is supposed to do. (...) Well, doing grep '^1 24 ' on the parts (...) (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
(...) Not exactly -- just use the current contrast color as the main color for the subfile. Whenever a subfile is rendered, it should already be looking up the local contrast color based on the local main color. Steve (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
(...) Right... but what should the contrast color be defined as within the subfile? The same? >> Mark (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
(...) The contrast color within the subfile would be defined in the normal way - use the main color for the subfile, and look up the contrast color from the color table. The fact that the originating linetype 1 used color code 24 shouldn't matter by (...) (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
Okay... that makes sense. But what if the contrast color for the current file's main color is just an RGB value rather than a color index? What should the subfile's contrast color be set to in that case? Thank you for your help, by the way. >> Mark (...) (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
(...) In the case of some kind of direct color, I guess the rendering program is free to do whatever it wants. The simplest action would be to default to black (either LDraw 0, or RGB #000000). I'd be interested to hear what actual rendering (...) (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
(...) Actually, that grep doesn't return anything. '^[ \t]*1 24' does return hits from three files, though. Every single place in the library that this is used, it's used in a reference to one of the edge primitives. The edge primitives use color 24 (...) (18 years ago, 5-Sep-06, to lugnet.cad.dev)
 
  Re: What does a subpart with color=24 mean?
 
(...) Well, one that I have gives a warning message that says it can't handle color 24 and substitutes 16 for such lines. But I wasn't sure if that was correct behaviour. Another one that I've played with quietly accepts such lines, but appears to (...) (18 years ago, 5-Sep-06, to lugnet.cad.dev)
