I tried the getResource command in revolution, it doesn't seem to
work with Mac OS X .rsrc files. For instance when I run this script
from a button:
on mouseUp
local myFilePathName
local myResourceData
local myResult
put "/Users/Dave/Desktop/iTunesImages/myFile.rsrc" into
myFilePathName
put getResources(myFilePathName) into myResourceData
put the result into myResult
end mouseUp
myResourceData and myResult are both empty, yet when I look at the
file with ThemePark it show the Icons and Files ok. The myFile.rsrc I
used here was taken from iTunes in the Resources folder inside the
App Package.
What I really want is to convert the pngs and icns into JPEG images.
The getResources function works on the resource fork only, added back in
the OS 8.5 days and increasingly Apple is migrating away from using
resource forks so it's not so useful under OS X.*
So while that explains why you're not getting what you're looking for
with that, I'm confused about what's in iTunes .rsrc file. It seems its
icons are stored in several dozen .icns files within the bundle's
"Resources" folder. With a tool or external that can extract the image
data from them (could conceivably be done with a script too) it would
seem those icns files are where you would obtain those images.
Yet the iTunes .rsrc file weighs in at more than 10MB. What's in it?
* I'll take this opportunity to make another prediction about Apple:
one of the next major changes to the OS seems likely to be migrating
away from HSF to the same file system used by Unix/Linux. The downside
to this migration is the final end of the old resource forks, but the
upside would be complete compatibility with most of the non-Microsoft
world while further marginalizing Windows, drawing attention to it being
a technological island.
Similar in scope to the other major transitions (68k->PPC, Classic->OS
X, PPC->Intel) this will be somewhat disruptive during the transitional
phase, but will also carry an upside for vendors as the previous
transitions did by artificially enhancing demand for software upgrades
which would otherwise be dependent on features alone.
I'll go further out on a limb to predict this will be announced within
the next three years.
