#68425 — Invert Screen (Universal Access)

Hi,

I have developed rather severe cataracts over the past year and it is 
becoming increasingly more difficult to use my mac while I await 
treatment.

First, I'm still using Leopard (10.5.8) so my OS is a bit behind the 
times, but maybe someone here can still help me out.

There's an option in Universal Access to invert the screen colours using 
cmd-ctl-opt-8 which makes text much easier to read. Unfortunately, this 
option also makes photos and video entirely uninterpretable.

I'd like to find a way to write a script which will automatically invert 
the video when certain applications are foregrounded and uninvert it for 
others (and also change desktop pictures so the desktop remains 
consistently dark), but I'm not sure if it is even possible to associate 
a script with a particular application. Does anyone know if this is 
possible? and if so do you have a link to someplace which might describe 
how to do this?

Also, while I know how to toggle the video, I've been unable to find 
anyplace where one can actually access the current state of the display. 
I'm assuming there must be some variable accessible via the terminal 
which contains this info, but I have no ideas what it is called. Any 
suggestions?

I suspect this may not be possible but thought I would ask...

It's not really worth all the effort. It's much easier to simply push
cmd-ctl-opt-8 as needed.

OK -- I'm starting to see the scripting the behaviour of individual 
applications is probably not worth it, but I'd still like to find a way 
to have the toggle also effect the desktop pattern -- dark desktops are 
easier on my eyes, but toggling a dark one leads to a blindingly bright 
one.

A 50% gray desktop may be dull, but it will be exacly the same, 
whether reversed or not.

Unfortunately, my eyes require something much darker than that.

So do a simple web search for things like "applescript dark mode" to
find sample code like this, and then modify it to do what you want:

As I mentioned in my initial post, I'm still running leopard.

I don't think I gave you any indication that the above link was the only
web page on the internet regarding scripting a solution. My goodness,
some folks seem to be completely helpless sometimes. Please use your
brain a bit. Like I said, do a simple web search. Since you seem to be
unwilling or unable, I'll go ahead and do just one search for you:

<https://duckduckgo.com/?q=10.5+invert+screen+applescript&t=osx&ia=images&iax=1>

Somewhat unsurprisingly, the very first hit is:

<http://macscripter.net/viewtopic.php?pid=82131>

I will leave further searches for you to do as an exercise in
creativity. 

Enjoy.

I appreciate the assisstance as the above link proved useful.

Just as an aside, the issue isn't an inability to search, but an 
uncertainty over which terms to search for. My attempts were producing 
results which were far too broad, and as I am still getting used to my 
newfound inability to read, sifting through even a relatively small set 
of results is proving troublesome. The search-terms you suggested in 
your first post were Yosemite-specific.

Fair enough. I had forgotten that you were using an older system when I
did that search. The second search was simply putting the terms "10.5",
"invert screen", and "applescript" together in a search query to match
your requirements.

Well, it depends... I too always use the inverted mode in combination 
with enlargement due to my low sight, and I'd indeed like if it was 
possible to find an automatically way when videos and photos - or any 
other graphics in a document ocours.

I once was told from a guy here at Apple Denmark that it isn't possible 
to make this work correctly. So I always use the keyboard commands. It 
irritates me though each time if I'd like to see a picture in real 
colour, since using the commands always gives a sharp flush in the eyes 
when you go from a black background to the normal white - especially if 
I've zoomed to normal size before reverting to normal.

Working in Photoshop is rather easy though. When I've opened a picture, 
it's just to press COM+I to 'invert' the picture. And when the whole 
system already works inverted, the picture is shown in normal colours. - 
But it indeed requires quite a lot of learning to use the various 
settings when/if you want to correct a picture - and don't forget to 
're-invert' the picture before saving - else people with normal sight 
will see the picture like an old film negative.:-)

Cheers, Erik Richard

Even if it was possible, having the computer automatically switch
between "normal" and "invert" modes would likely be even more annoying
... at least when pressing the keys you know it's going to happen and
happens when you want, rather than unexpectedly or when you click on
the wrong application in the Dock, etc.

In OS X Yosemite there is the new "Dark Mode" which is something
similar to what you want - dark backgrounds, white text, and normal
images.

The other way would be to "theme" your Mac. Depending on the version of
Mac OS X, there are utilities around that let you change the fonts,
colours, etc. of applications that follow the rules (there are some
applications that naughtily do not follow the rules though).
