I thought that Icon-O-Matic would read an icon rdef file, but apparently not...
However, the (text) icon data in the rdef is just a hex representation
of the (original) binary hvif, which Icon-O-Matic *will* read.
So -- as a service to the community (:-)) -- I present a little Ruby script
that converts an rdef (containing *only* the 'VICN' section back into
an hvif, "rdef2hvif.rb":
#! /bin/env ruby
open(ARGV[0]) {|f|
out = ""
outname = File.basename(ARGV[0], ".rdef")+".hvif"
f.each_line {|ln|
part = ln[/\$"(.*)"/,1]
if part then
i = 0
while (v = part[i,2]) != ""
byte = v.hex
out << byte
i += 2
end
end
}
open(outname, "w") {|hvif| hvif.write(out)}
}
If you haven't got Ruby, get it from HaikuDepot. (I would have
written it in Python, but it's so long since I've used it that I'd
have had to look *everything* up, rather that just half of it!)
To use it just make the script executable and run:
rdef2hvif.rb <source>.rdef
where <source>.rdef is a file containing only the icon data
(use an editor if necessary). It should generate "<source>.hvif",
which you can import into I-O-M and export an SVG.
HTH,
