From: Rowland McDonnell on
So here's me, trying to attach a picture of a Vincent Black Lightning[1]
to my copy of Richard Thomson's `1952 Vincent Black Lightning'.

What I see displayed using the various iTunes views of attached artwork
looks low-res and/or badly anti-aliased.

Okay, so test to see if something's gone wrong with the transfer of data
from `downloaded image' to `applied to the track in iTunes'. How to
test? I copied the image attached in iTunes by Get Info -> Artwork and
copying the image I saw there (after putting a totally different image
in the paste buffer to confirm that this step functioned).

`Open new image using Clipboard' in GraphicConverter shows me what I
copied from iTunes.

Lo and behold, what I get is the full resolution image as downloaded
from:

<http://upload.wikimedia.org/wikipedia/commons/5/52/VINCENT_Black_Lightn
ing.jpg>.

But as displayed in iTunes, it's ropey.

Does anyone have a clue what's going on and what might be done about it?

Rowland.

---------------------------------------------------------------

Sorry about this, but I get enthusiastic when I meet Vincents. One used
to be parked up on the street down the road from me when I was young -
on summer's weekends, you'd often see it. Black and chrome and shiny
and lust-provoking. Smelt hot too, some of the times I passed - not
being parked outside just for pose value, then.

[1] If I had one, I'd give it modern brakes and modern suspension
improvements. And a modern fuel filter[2]. And possibly modern wheels
so I could use modern tyres. And then I'd *have* to fit a supercharger
and nitrous oxide injection so I could run away from the Vincent Owners
Club members trying to hunt me down and kill me.

[2] Anyone else see Richard Hammond run into a problem in that line on
Top Gear? - riding a Vincent Black Shadow[3] IIRC.

[3] The Black Lightning is basically a Black Shadow with go-faster
mods. REAL go-faster mods, for serious racing or just going bloody
fast. I'm not sure I'd want 150mph on a bike with brakes like that.
They were considered good brakes in the 1950s, compared to other 1950s
motorcycle brakes[4]...

[4] I had a 1970s Iron Curtain two-stroke with a better front brake than
the monster in the picture. No, really - a twin leading shoe drum,
about the same size and so better[5], and it actually turned off
properly when you let go of the lever. Huh? Read up on Vincent brakes.
The bikes are magnificent, but not without a few flaws.

[5] The Vincent brake illustrated is the usual Vincent two-sided
single leading shoe (sls) front brake; so while it's actually got two
leading shoes, because each side is one leading shoe only, it counts as
`two sls brakes' rather than as a twin leading shoe (tls) brake.
They're bloody wide drums, mind, so they're two proper-sized sls brakes
at the front, but tls is better all other things being equal. My CZ
braked like it was hitting a brick wall during my ownership[6], although
that did take weekly maintenance (clean out the dust and re-adjust the
shoe balance). Since my riding style (and hence life) depends on having
brakes that really work, I did the maintenance.

[6] When it was all sweet, I could pull a stoppie in the right
conditions. Pretty damned astonishing on a 1970s Iron Curtain 125 and
I'm pretty sure you can't do it on a stock Vincent. The CZ brake[7] was
meant to be good enough to halt the 350 twin with side car, and I had
the single cylinder 125.

[7] Yeah, just the one design. All CZ's road motorcycle wheels were
identical. You got front or rear fitment or tls or sls brake depending
on the plate that went over the side - holding the shoes, actuators,
torque reaction fitment (CZ had an odd arrangement), etc. One design of
brake shoe needed, one design of brake cam, etc., etc.

(The casting was marked `CZ Jawa Desta'. Desta did forklift trucks
IIRC, but I might be mistaken. I assume that the Czech authorities ran
CZ/Jawa/Desta as a single concern with multiple brands.)

So one set of tooling does for all front and rear wheels on all
motorcycle designs. Which is practical when the range is nothing but
utilitarian two-strokes ranging from 125cc single to 350cc twin. The CZ
moped originated with a different firm and I think they always made it
in a different factory - anyway, totally different line of development
and manufacture.

I'm not sure what you did, but I copied the image for which you gave a
url, using Cmd-Shift F4 and select, to produce a .png. Dropped that onto
the picture space for a tune in iTunes 9.1.1, OS 10.4.11.

It displays full rez in iTunes when I click on the thumbnail- the way
they all do.

This may be another round in your struggle with 10.6?

You are sure what I did: I downloaded the original file - as I mentioned
above (you kept that part of my original post in place above).

Except, of course, that we have previously established that is not the
case. We have established the need for file drag-drop since copy-paste
often fails to provide a full-res image.

I think it's more likely that my eyes are better than yours, and that
what you call `full rez' is what I call a ropey version possibly due to
iTunes doing antialiasing the bad way.

You speak for yourself. In this case the copied image is of excellent
quality.

But I repeated it your way. Works perfectly in iTunes 9.1.1, just as
before. Looks very similar too.

So I still don't know what's going wrong except for your ongoing battle
with 10.6.3.

Is there any way you can put a screenshot up for me to see for myself?

What do you mean by that?

The image I see is - as far as I can make out by peering closely at my
1920x1200dpi 24" LCD iMac's screen - suffering from particularly bad
anti-aliasing when displayed here by iTunes.

My eyes are quite a lot younger than yours and almost certainly better.

Graphic Converter does particularly good anti-aliasing - but when I turn
Graphic Converter's anti-aliasing off and shrink the Graphic
Converter-displayed version down to the size displayed by iTunes, it
looks perfect in comparision.

So it's not that. The Vincent is displayed at much less than optimum
resolution for some reason - quite unlike other artwork I've added using
the same method with iTunes 9 and MacOS X 10.6.

Peter, there is no on-going battle with 10.6.3. I have no idea where
you get these ideas from.

To put things in perspective, I've had trouble getting artwork into
iTunes before now - the last trouble, using iTunes v<recent> on MacOS X
10.6.Iforget, was resolved by someone suggesting that I drag-and-drop
the file rather than going via the clipboard, because the clipboard
route was buggy. And so it came to pass that I learnt how to avoid a
bug in MacOS X 10.6.

This is different - it's a new problem

Rowland.
