| | | | | (...) Hi Mark, I'm pretty sure there is no standard for that, and it depends on which renderer you use. ROSCO (18 years ago, 5-Sep-06, to lugnet.cad.dev)

|
| | | | | (...) OK, I was partly right. There actually is a standard defined for colour extensions, you can view it here (URL) it only applies to colours defined either in ldconfig.ldr, or in the part files or model files themselves. And it is still up to the (...) (18 years ago, 5-Sep-06, to lugnet.cad.dev)

| | | | (...) 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)

| | | | (...) 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)

| | | | | (...) 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)

| | | | | | (...) 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? —Steve Bliss
|
| | | | | | (...) 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? —Mark Tarrabain
|
| | | | | | 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)

| | | | | | (...) 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)

| | | | | | (...) 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)

| | | | (...) 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)
