tcl and 'winfo rgb'

[Matthias Meier]

Hello,

as far as i know the wish can't be startet without an display.

To convert tcl-colors to html-colors i use

eval format "#%04x%04x%04x" [winfo rgb . seagreen]

How can this be done in 'batch-mode' (without an display)
Is ther a tcl-way to do this?

Thanks, Matthias

[jr]

can you not simply use the values in 'rgb.txt' directly?

Note: if X11 is not installed (eg on a server) rgb.txt won't exist.

(Nothing stopping the OP from grabing a copy rgb.txt from the xorg
code, though...)

Hello Matthias,

The Tcl3D source code distribution (www.tcl3d.org) has a file called
tcl3dUtilColors.tcl. This file contains a list of color names with their
corresponding RGB values and some utility functions.

Hope that helps,

Paul

There's also a table in the tk source code, in xlib/xcolors.c
