Shell scripts

Hello,
i want a shell script command, where creates a pdf -file by merging
Jpg-files (or tiff-files) in this one, new print-format.
Then, this pdf- file has to be being created, saving it in the same
path of these image-files;
this means that i've 100 files of items, from where 50% are zip-files
and 50% are tiff-or jpg-files, both in the same path.

i want to clean up with all these image files, converting these in one
PDF file

No. But it would be fine, if the script compresses the images too. Not
to much, let's say Quality 80%, also a compression rate of only 20%

Yes. consumes minor CPU resources and works faster, at all this files

I've not found any information about converting images to PDF, (Image
Events Dictionary) but, but..
it had seemed for me too, that Image Event is capable to do this, hm..

I'll give it a look.


Look at this first code: (has changed the unix-commands for Leopard?)

tell application "Finder"
set results_folder to ((path to desktop) & "Pdfs" as text)
repeat with i from 1 to count items in front window
set this_item to item i of front window
if class of this_item is folder then
set new_name to name of this_item
set source_file to (this_item as alias)
--display dialog (source_file & return & return & new_name & return
& return & (folder of front window as alias) as text)
my process_item(source_file, new_name, results_folder)
end if
end repeat
end tell

on process_item(source_file, new_name, results_folder)
-- NOTE that the variable this_item is a file reference in alias
format
try
set the source_item to the quoted form of the POSIX path of the
source_file
set the target_path to the quoted form of the POSIX path of
(((results_folder as string) & new_name) as string)
with timeout of 900 seconds
do shell script ("pstopdf " & source_item & " -o " & target_path)
end timeout
on error error_message
tell application "Finder"
activate
display dialog error_message buttons {"Cancel"} default button 1
giving up after 120
end tell
end try
end process_item

this command is not the right one, it converts only the old postscript
-format into new pdf-files. I dont'know who to start, for shell script
tutorials. But, how being has sayd Jolly Roger, thats better to ask in
another forum. Thanks nevertheless.

A few questions:

1. What will you do with these PDF files once they are created? I can't
think of how they would be very useful.

2. Are you worried at all about image quality degradation once they are
in the PDF file?

3. Do you want to ignore all files (ZIP files, etc.) except the images
in the source folder, or did you want your script to unzip compressed
images in the folder?

4. Does the PDF have to be created by a shell script, or would pure
AppleScript do?

I believe the Mac OS X built-in "Image Events" scripting addition will
convert images to PDF for you; but I'm not sure if it will let you
combine multiple images.

I'm afraid if you're looking for a command-line tool to convert images
to PDF, this isn't really the right news group to ask. You'll probably
have better luck with a Google web search of maybe a visit to
<http://soureforge.net>.

Import them in a new iPhoto album, choose "Print" and use the "Save as
PDF" option.

Try this Automator action:

who writes such scripts? this Automator-workflow is composed of 4
parts:
1)get selected finder items
2)sort finder items
3)Applescript (unfortunately, it does not work)
4)combine pdf pages

i mean, its very interesting to read this kind of scripting.

thats right! i'm of the same opinion.

>/System/Library/Printers/Libraries/convert command-line tool to convert
each image to PDF.

Yeah, in my new applescript its a basic part of the code.

Thanks very much for your help, Roger,
but i think that i'm burned out for today. i'm simply to tired to
write more one letter;i'll check and adjust the default selection
handler for tomorrow and i wish everybody a good night (is there a
difference between day and night if somebody works or sleeps ? i think
no. So, good night.)

Whoever runs the web site hosting the action, I imagine.

The action works. It's just the AppleScript portion *assumes* you will
have selected image files (as opposed to having a *folder* selected). So
try it with images selected rather than a folder selected. Changing the
script to handle folder selections would be relatively easy.

Notice that the script uses the
/System/Library/Printers/Libraries/convert command-line tool to convert
each image to PDF. You could do *all* of the Automator action steps in
pure AppleScript quite easily. Mainly you would need to figure out how
Automator combines PDFs together in step 4 and do that in pure
AppleScript.

How to use specific shell tools involves deciphering their man pages.
But how to (and how not to) use AppleScript's do shell script is
