#61 ASCII to XBM conversion script

[Eric Melski]

Attached is the Tcl source to convert ASCII art
diagrams like:
<pre>
@@@@@
.@@@.
..@..
</pre>

into XBM format suitable for passing into [image create
bitmap -data ...]. This script is prompted by TIP 71
and is submitted as an
alternative to the suggestion of simply adding more
hardcoded
bitmaps into Tk.
