Mark,
I was having all kinds of problems with the write to and read from
file method, mostly path issues. Don't forget I have to have this work
in AS, VB and in RR in order to be of use to me on both Mac and
Windows platforms.
And, I was not getting RR to read the file correctly from the hex
data returned straight from the AS script.
Nothing else in my library writes to the users disk and I wanted to
keep this consistent if I could.
So I looked into the clipboard info and found that AS and VB will
convert the raw data into binary on the clipboard. So getting RR to
just read the binary clipboard instead of the hex data seemed like the
logical step. However paste was not working in RR correctly for me and
after a while I thought maybe I was not copying correctly from AS. So,
I looked up in the scripting additions library for clipboard where it
does state:
set the clipboard to v : Place data on an application’s clipboard.
Use inside a ‘tell’ block and activate the application first
set the clipboard to any : the data to place on the clipboard
the clipboard v : Return the contents of an application’s clipboard.
Use in a ‘tell’ block after activating the application
the clipboard
[as type class] : the type of data desired
→ any : the data
clipboard info v : Return information about the clipboard
clipboard info
[for type class] : restricts to information about only this data type
→ list of list : a list of {data type, size} for each type of data on
the clipboard
ANYWAY, after playing around all day and getting frustrated I decided
to go back to my script that just pasted on the clipboard (Finder?)
and do it different this time from within RR instead. It now works
consistently without a paste in RR, but rather a
clipboardData["image"] instead:
Applescript: (This successfully puts the artwork converted to binary
on the clipboard every time, <name> and <playlist> are replaced.)
try
tell application "iTunes"
set myHasArtwork to the artworks of track "<name>" of playlist
"<playlist>"
if myHasArtwork is not "" then
set myTrack to the (data of artwork 1 of track "<name>" of playlist
"<playlist>") as picture
set the clipboard to myTrack as picture
return myTrack
end if
end tell
end try
Then in Revolution:
-- set up a correctly sized invisible image to store the data in and
then use it's ID for my buttons and or other images
put the clipboardData["image"] into tTemp
put tTemp into img "Template"
put the id of img "Template" into theResult
put "Image ID:" && theResult into field "Sample"
-- Now put the new image into a new sized and locked image or set
up for the icon of a btn etc.
put image id theResult into image "Album Artwork"
Well, after a long day, this is now working consistently and if I need
to save the file I can now do it from within RR with a simple path
instead of having to set up paths in AS and VB and RR.
Thank you for you help and suggestions,
Tom McGrath

Tom,
Did you see my last reply regarding your problem concerning PNGs?
I don't know where you got the instruction to activate an
application before setting the clipboard, but this seems like
nonsense to me. The clipboard usually works at system level. It
shouldn't be necessary to do this inside a tell block.
Can't you just have AppleScript return the data to Revolution and
use a Rev script to read the picture from the result, like you did
earlier?
Best,
Mark
