[Qemu-devel] [PATCH] Makefile.target: set icon for binary file on Mac OS X

IIUC sips modifies ../pc-bios/qemu-nsis.ico (adding a resource fork?),
so it's not possible to put it in Makefile.target.  If "sips" is invoked
twice by two different recursive invocations of Makefile.target, bad
things can happen.

I think we can simply distribute tmpicns.rsrc as pc-bios/qemu.rsrc instead.

These two commands can be added after

$(QEMU_PROG_BUILD): $(all-obj-y) ../libqemuutil.a ../libqemustub.a
        $(call LINK,$^)

instead of adding a new rule.  There is no need for the comments.

Ok. Will implement your suggested changes. Thank you.

Why not just use the sips --out option to specify a different
output file? That way we automatically put the current icon
into the executable, and don't have to update a hand-created
qemu.rsrc file in git if we change the icon in future (and I
bet if we don't have the rules for doing this in the makefile
then nobody will remember how to do it).

As a bonus we don't have to keep that file full of ugly high-bit-set
characters in C comments in git :-)

I suspect the Windows icon is not a great match for Mac OS X which likes
to have big sizes (48x48 or 128x128).  If you want to generate the .rsrc
file automatically, the right source probably would be the .svg file,
and doing the conversion in the Makefile probably isn't entirely
feasible.  It would need extra build dependency and rounding errors
would make it harder to achieve reproducible builds.

And depending on the complexity of the SVG not all methods produce the
same result. Although it was years ago I recall having a hard time
getting gradients to render correctly with ImageMagick. You'll want to
compare the ImageMagick/GraphicsMagick and rsvg (apt:librsvg2-bin on
Debian) outputs.
Although the current ImageMagick seems to work fine on the logo here.
But you'll have to find how to properly specify the size of the SVG (and
not use -scale since it'll resize the bitmap, and make it 128x127).

OTOH:

rsvg-convert -w 128 -h 128 ./pc-bios/qemu_logo_no_text.svg > qemu-r.png

seems to generate a proper png with transparency.

It seems inkscape can do it as well, but it's probably a larger dependency:

Definitely true.

Plus the sips command doesn't work with svg files.

Ok, so I'll apply v3 to my tree as soon as I get a Tested-by.  Please
take a look into providing a .rsrc file with larger-sized icons (I think
you can add more than one to a single .rsrc file?) and, when you do
that, document in pc-bios/README how the resources were built.

Thanks,

Paolo

When I was inspecting the icon using the genie feature of Mac OS X's dock, the icon looked very sharp at full size, so I didn't see a problem with it. What size do you have in mind?

I was thinking of 16x16, 32x32, 48x48 and 128x128.

What advantages do you think this would give us? Doesn't Mac OS X already resize the icon for you?

128x128 is used in the Finder in some cases IIRC.  Downsizing from
128x128 to 16x16 isn't great, so whatever sizes are already in the .ico
file should be kept (these are 16x16, 32x32 and 48x48) especially if you
saw that the 48x48 icon is sharp in the dock.  But remember that this is
just a nit.
