I have a script to shrink pictures that stopped working under 10.15.

I’ve lost track of this thread, and this may be known, but the increased file size could be a result of the following line:

save openedFile with icon

Change it as follows to see reduced file sizes:

save openedFile

In my testing with a 270 KB PNG original, the output file contained 410 KB with icon and 87 KB without icon. This is with Yvan’s must-work script from post 25.

Peavine, greetings.

Changing that line makes no difference. As before, a 1.8 MB jpeg becomes 2.2MB. A 3.2MB png stays the same size. All that happens is that the size of the icon picture becomes bigger.

I am really stumped that it works on your end and not on mine.

I am on OS 10.15.4 on a MM 2020.

I don’t understand that either. There’s some other factor at work that we are missing.

I understand that you want to use Image Events but have your tried my script from post 13. It uses sips and this could be helpful to understand what’s happening. On my Catalina computer, this script worked with PNG and JPEG files on boot and external drives.

Yvan I am back at the machine. Tested. And as before no cigar. A 1.8 MB jpeg becomes 2.2MB. A 3.2MB png stays the same size. All that happens is that the size of the icon picture becomes bigger.

Why would it not work?

Peavine, as to post 13.
It works and it does not.

It changes a png from 3.2MB to 590KB regardless of what we put in the sips dialog.

And an 1.8MB jpeg reduces to 45kb with the script below.

As said, it even works like this and has the same result.

I don’t know what happening then. Sorry I couldn’t help.

May you run :

Yvan (post 34) here is what it reports for a jpeg pic:

origDimensions : 3264, 1836
origResolution : 72.0, 72.0
newDimensions : 800, 450
newResolution : 72.0, 72.0

however the pic went from 1.8 to 2.2 MB. So, it shrunk its size as in dimensions but enlarged the size as in KB.

For a png a similar thing happens. The size (MB) stays the same and it reports:

origDimensions : 1920, 1080
origResolution : 72.0, 72.0
newDimensions : 800, 450
newResolution : 72.0, 72.0

The aim of my original script was to redse KB. So, the 1.8 MB became like 110 KB.

Yvan as to the script in post 36, nothing happens. Well I get a box to click.

OS 10.15 test:Users:e:Desktop:1 copy 5.png
‘/Users/e/Desktop/1 copy 5.png’

So, it did what it was supposed to do, If you look at the script in message 36, the call to SIPS was deliberately disabled.

Now that we know that the needed infos are correctly passed, try the version with the call to SIPS enabled:

on open draggeditems
	--set draggeditems to choose file of type {"public.jpeg"} with multiple selections allowed
	set text1 to my recolle(draggeditems, linefeed)
	repeat with aFile in draggeditems
		set contents of aFile to quoted form of POSIX path of aFile & space
	end repeat
	set text2 to my recolle(draggeditems, linefeed)
	
	display dialog text1 & linefeed & text2
	do shell script "sips --resampleHeightWidthMax 800 " & draggeditems
end open

May you send one or two of your pictures to my mail address : <koenigyvan mac com>

Yvan KOENIG running High Sierra 10.13.6 in French (VALLAURIS, France) samedi 23 mai 2020 19:10:30

Same result as before.

send.

Thank you.

Really simple.
Your jpeg is one of the ‘corrupted’ ones which are available since a few months.
When I looked at its contents with an hexadecimal editor I found a large number of null bytes at its end.
These bytes prevent SIPS or Image Events to achieve their job.
I removed these extraneous bytes so, the original file (1754025 bytes) became a 1560661 bytes one.
When I treated it with SIPS I got a 52949 bytes one.

Some days ago I wrote a script designed to clean such ‘corrupted’ files.
Shane Stanley gave me a more efficient one.
Here it is.

Yvan,

Here’s another approach. It’s still a bit on the dirty side, but I see the first file I tried contained FFD900 more than once. The problem is to avoid accidentally running the code on a file that has already been trimmed. There’s probably a more efficient way, but it shouldn’t be too bad:

use AppleScript version "2.5" -- macOS 10.11 or later
use framework "Foundation"
use scripting additions

set theFile to choose file
--search for FFD900
set b64String to "/9kA" -- FFD900 in Base64
set b64Data to current application's NSData's alloc()'s initWithBase64EncodedString:b64String options:0
set theData to current application's NSData's dataWithContentsOfURL:theFile
set dataLen to theData's |length|()
set theRange to theData's rangeOfData:b64Data options:(current application's NSDataSearchBackwards) range:{0, dataLen}
if |length| of theRange = 3 then
	-- make sure only nulls after it by making base64 string of the rest, then looking for other than A or = in it
	set maxRange to current application's NSMaxRange(theRange)
	set endData to theData's subdataWithRange:{maxRange + 1, dataLen - maxRange - 1}
	set endB64 to (endData's base64EncodedStringWithOptions:0)
	set newRange to endB64's rangeOfString:"[^A=]" options:(current application's NSRegularExpressionSearch)
	if |length| of newRange is 0 then
		-- we know it's only nulls
		set eof theFile to ((location of theRange) + 2)
	end if
end if

On my side I encapsulated it in a script which filter Jpegs in every cases in droplet as well as in applet.

use AppleScript version "2.5" -- macOS 10.11 or later
use framework "Foundation"
use scripting additions

on run
	set theFiles to choose file with prompt "Sélectionner un ou plusieurs fichiers jpg" of type {"public.jpeg"} with multiple selections allowed
	repeat with aFile in theFiles
		my removeGarbage(aFile)
	end repeat
end run

on open theFiles -- alas list of drag & dropped items
	tell application "System Events"
		repeat with aFile in theFiles
			if type identifier of aFile is "public.jpeg" then my removeGarbage(aFile)
		end repeat
	end tell
end open

on removeGarbage(theFile)
	-- handler written by Shane Stanley on 2020/04/30
	--search for FFD900
	set b64String to "/9kA" -- FFD900 in Base64
	set b64Data to current application's NSData's alloc()'s initWithBase64EncodedString:b64String options:0
	set theData to current application's NSData's dataWithContentsOfURL:theFile
	set dataLen to theData's |length|()
	set theRange to theData's rangeOfData:b64Data options:(current application's NSDataSearchBackwards) range:{0, dataLen}
	if |length| of theRange = 3 then
		-- make sure only nulls after it by making base64 string of the rest, then looking for other than A or = in it
		set maxRange to current application's NSMaxRange(theRange)
		set endData to theData's subdataWithRange:{maxRange + 1, dataLen - maxRange - 1}
		set endB64 to (endData's base64EncodedStringWithOptions:0)
		set newRange to endB64's rangeOfString:"[^A=]" options:(current application's NSRegularExpressionSearch)
		if |length| of newRange is 0 then
			-- we know it's only nulls
			set eof theFile to ((location of theRange) + 2)
		end if
	end if
end removeGarbage

In an other message, Shane wrote : If you save it from Script Debugger, you will see in the Resources pane that you can restrict drag-and-drop to just jpeg files.

Try it and let all of us know if this time you get the wanted result.

PS: not sure that the problem is solved for you. Here, when I apply SIPs on your original file, it’s correctly reduced.

Yvan good morning.

I am not able to make it work. I am now testing under 10.13, like you.

Yes the script shrinks the picture and always to 229MB.

I cannot control the size in any way, I tried numbers from 1 to 50000 and the output size is always the same.

So I started testing.

As you see in the script below I can disable almost of all of it and it still works.


on open draggeditems
	--set draggeditems to choose file of type {"public.jpeg"} with multiple selections allowed
	--set text1 to my recolle(draggeditems, linefeed)
	--repeat with aFile in draggeditems
	--set contents of aFile to quoted form of POSIX path of aFile & space
	--end repeat
	--set text2 to my recolle(draggeditems, linefeed)
	
	-- display dialog text1 & linefeed & text2
	-- do shell script "sips --resampleHeightWidthMax 50000 " & draggeditems
end open
#=====

--on recolle(l, d)
--local oTIDs, t
--set {oTIDs, AppleScript's text item delimiters} to {AppleScript's text item delimiters, d}
--set t to l as text
--set AppleScript's text item delimiters to oTIDs
--return t
--end recolle

#=====


This is not possible. So I pasted the clean text in a new one and it does not work.


on open draggeditems    
end open

Now, I am not an expert here, but something is funny. I would guess that there is code that keeps ‘hanging’ in the script. Or?

What do you think and could this be the cause of the challenges I have with the script?

Now my original script:


tell application "Image Events"
    launch
end tell
on open draggeditems
    repeat with currentFile in draggeditems
        tell application "Image Events"
            set openedFile to open (currentFile as alias)
            --Part 3:
            set fileLocation to the location of openedFile
            set fileName to the name of openedFile
            --Part 4:
            scale openedFile to size 800
            save openedFile with icon
            close openedFile
        end tell
        --Part 5:
        tell application "Finder"
            set the name of file fileName of fileLocation to ¬
                (fileName)
        end tell
    end repeat
end open

It still works but I can not influence the size (like in the other proposed script here) anymore. I had 3 scripts, where I had different numbers (here 800) like 700 and 100. This would influence the size. And it still does if I use the originals. But as soon as I copy to a new file or change the number it goes to 54 mb.

I can’t guess what you made wrongly but you did.

The script above does absolutely nothing !
So I don’t understand what means your statement : and it still works.

The script above, which is in fact exactly the same than the first one, does absolutely nothing !
So I don’t understand what means your statement : and it does not work.

Yvan greetings, me reporting. I saved all 3 of them. 800 and 1200 work if I drop a file on it and give different sizes.

1600 does not work saved as an app if I drop a file on it. It does nothing.

If I however run it, it gives me the change to select a file and gives me 3 boxes.

and shrinks it to 320KB.

I suspect we arrived, did we not? I need to test later under 10.15, and will report.

Question, I now run them without repair. I assume there is no need for this?

correct and it still shrunk the picture.

this is what I did. I opened the app with SE, took all the lines out, saved it as the original app and it worked as before. it should not but it did.

do I understand it? no I do not.

a bug? possibly.
