apple scripting for Preview in Mojave

iMac (Retina 5K, 27-inch, Late 2015); Processor 4GHz Intel Core I7; Memory 16GB 1867 Mhz DDR3; Startup Disk iTB Fusion; MacOS Mojave (10.14)

I had previously had run an Apple Script on the Preview Application running OS 10.12. That script doesn't run on 10.14. In fact, when I open the Script Editor in the Utilities Folder and look for applications that it will work with Preview isn't listed. Are there plans to add Preview scripting features? I have a desperate need to use Preview to convert PDF files to JPEG files after opening the PDF file from the Print Directory.

I used the following Apple Script in OS 10.12.

-- Click the “File” menu.

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "click menu bar item \"File\" of menu bar 1 of application process \"Preview\""

my doWithTimeout( uiScript, timeoutSeconds )

-- Export…

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "click menu item 13 of menu 1 of menu bar item \"File\" of menu bar 1 of application process \"Preview\""

my doWithTimeout( uiScript, timeoutSeconds )

-- Press ⌘V

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "keystroke \"v\" using command down"

my doWithTimeout( uiScript, timeoutSeconds )

-- Make a selection from the popupbutton.

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "click pop up button 1 of group 2 of sheet 1 of window 1 of application process \"Preview\""

my doWithTimeout( uiScript, timeoutSeconds )

-- PDSC Picture Folder

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "click menu item \"PDSC Picture Folder\" of menu 1 of pop up button 1 of group 2 of sheet 1 of window 1 of application process \"Preview\""

my doWithTimeout( uiScript, timeoutSeconds )

-- Make a selection from the popupbutton.

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "click pop up button 1 of group 1 of sheet 1 of window 1 of application process \"Preview\""

my doWithTimeout( uiScript, timeoutSeconds )

-- JPEG

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "click menu item \"JPEG\" of menu 1 of pop up button 1 of group 1 of sheet 1 of window 1 of application process \"Preview\""

my doWithTimeout( uiScript, timeoutSeconds )

-- Click the “Save” button.

delay 0.15

set timeoutSeconds to 2.000000

set uiScript to "click UI Element \"Save\" of sheet 1 of window 1 of application process \"Preview\""

my doWithTimeout( uiScript, timeoutSeconds )

-- Press ⌘W

delay 0.5

set timeoutSeconds to 2.000000

set uiScript to "keystroke \"w\" using command down"

my doWithTimeout( uiScript, timeoutSeconds )

on doWithTimeout(uiScript, timeoutSeconds)

set endDate to (current date) + timeoutSeconds

repeat

try

run script "tell application \"System Events\"

" & uiScript & "

end tell"

exit repeat

on error errorMessage

if ((current date) > endDate) then

error "Can not " & uiScript

end if

end try

end repeat

end doWithTimeout
