Paddy! What?! You read the Manual?! We done need no stinkin' manual!!!! I'm not sure that detail is in the App Store panel that shows all the hits of a search. Anyway, I downloaded and installed at least 6 different apps and it was the easiest and simplest to use. And it actually opened/worked!
ZoozReferring to the image entitled "Finder in top menu bar.png":
is this a window?
Nope. The clue is your own description, "in the top menu bar". Things in the "menu bar" are menus; a list of items that usually are actions you want an app to perform; Tell me "About Finder", open the "Preferences" for this app, "Empty" stuff in the "Trash", show me any "Services" that might be usable in this app, "Hide Finder", "Hide Others" apps. You will note that except where the word "Finder" appears in that menu, it could be referring to any application.
Generally, that "top menu bar" is simply referred to as "The Menu Bar". Windows often places a "menu bar" on every single window. So, in Windows, there is a "top" menu bar, but often umpteen additional menu bars. Apple did away with that even before with the Lisa.
A "window" is a dedicated, delineated area on the screen on the screen where an app can display information or ask for input. A window usually has clearly visible sides and (usually) hides what is 'behind' it. A Finder "window" is what can show you a list of files, documents and apps installed on you drive(s). Those windows help you to "find" things on your drive(s). A "window" is
not a menu.
Your second image is a window showing some of Finder's preferences. That window has the item that I suspected you had not checked: "Show all filename extensions". With it Unchecked, you will never see that all files have an extension on them. An extension is what tells the OS what app is assigned to open that file. It is a period followed (usually) by 3 letters. When the scanner created an image called "Sewing Club" it actually had an extension on it; Sewing Club.jpg. When you added ".jpg" to that name, you actually made the name "Sewing Club.jpg.jpg". That's one reason to check that box, it avoids confusing you and/or the computer and anyone you might send the file to.
The last image ("iText when I click to open it .png") is all I ever saw with iText until yesterday morning when it showed me a list of three different web names. I simply Quit iText and restarted it and got back the original menu offering opening a file or copying text from the screen. I suggest that you do the same and see if it will revert to the original menu as seen in an image below. The "Select Image File" is the item you should use.
A technical point: That image ("iText when I click to open it .png") is not what you see when you "click to open it", it is what you see when you additionally move the cursor over the item labeled "More".
We now know, thanks to
Paddy, that iText actually uses the computing power owned by Google for the heavy lifting required by OCR. If you don't want to touch Google, I can understand. I suspect (because I have not read the details of all the apps I downloaded and trashed) that most of them, especially the free ones, also use Google or some of the other on-line services. I'll leave that as an exercise for the reader.
I do apologize for not reading the details about iText and exposing your texts to Google. I should have known if it sounds too good to be true...
The point is, OCR needs powerful computing power. You can buy a dedicated app or get that power from many apps that use the computers available at places like Google and Amazon... or you can type it all yourself. Either way, work has to be done.
