Best way to create Windows .ico file for Emacs?

[KARR, DAVID (ATTCINW)]

I'm sure this is a FAQ, but I've spent several minutes searching
resources for the proper way to do this, but I just can't find it.

I have Cygwin Emacs 23.0.92 installed, which includes the "emacs.icon"
file, which I believe is an XPM file.  I need to create a Windows ICO
file.  Searching the net, I find 8 zillion tools for image conversion,
including many that provide the path that I need (xpm->ico), but what
I'm wondering is if there's a tool already installed (or available) with
Cygwin that can do this.  I looked through the ImageMagick man page and
didn't see it, which was the only obvious thing I knew to look at.

Hmm, it says "convert: Improper image header `emacs.icon'.
convert: missing an image filename `ico:emacs.ico'."

Perhaps this isn't actually an XPM file?  The header looks like this:

/* Format_version=1, Width=64, Height=64, Depth=1,
Valid_bits_per_item=16
 */
        0xFFFF,0xFFFF,0xFFFF,0xFFFF,0x8000,0x0000,0x0000,0x0001,
        0x8000,0x0000,0x007E,0x1C01,0x8000,0x0000,0x0006,0x1C01,

No, that's definitely not an XPM.  I would search the sources and see
how this is used; I suspect this is #include'd somewhere.

However, emacs includes emacs.png's and emacs.svg which are installed
into the hicolor-icon-theme.  Why not use those?  You have two options:

1) Use convert(1) for a 1->1 conversion.

2) In Ports, png2ico(1) allows embedding multiple images (e.g. different
sizes) into an ICO.

The emacs source contains several windows .ico files in the directory
nt/icons.  You can either download the source and locate them or you can
find them in the CVS repository:

   http://cvs.savannah.gnu.org/viewvc/emacs/nt/icons/?root=emacs

That's a Sun ICON file.  It looks like ImageMagick doesn't support
that, but PBMTools does:

$ icontopbm emacs.icon | convert - emacs.ico

Got it.  That's what I needed.  Thanks.
