- There may be more going on here than meets the eye, so to speak :-).
-
- Look at the RTF code in:
- /usr/lib/NextStep/Resources/English.lproj/HelpTemplate/Index.rtfd/TXT.rtf
-
- Just guessing, but it looks to me like they encode both a color
- value (red56,green70,blue144) that the Text object will use to
- display certain text on a color device, AND a gray value (gray333)
- that it will use to display the same text on a gray-scale device.
-
- However, look at the tiff files in the subdirectory. These appear
- to be used to draw index rule lines of various sizes. All the ones
- I checked used (51,68,153) for the color and showed as pure NX_DKGRAY
- in 2-bit mode. (I think this is the same color on the 0->255 scale
- as was posted earlier by Izumi Ohzawa as (0.2,0.26667,0.6) on the
- 0->1 scale.)
