My teacher sends us the notes after lecture in pdf format but he sends them all with a black background. Is there anyway I can get rid of the black background and just make it white so I don't waste ink when I print them?
Thanks!
MacBook Air, OS X Yosemite (10.10.5)
Are you familiar with Automator? You can make a simple 'application' that can extract the text in PDF's that have 'actual text' - Some PDF's may have images that display as text - that cannot be extracted so be sure to check your files work & don't delete the originals, it really depends on the format the teacher creates.
Open /Applications/Automator, create a new document, make it an 'Application'.
Find this next item in the 'Library' (use the search field) & drag it to the side that says 'Drag actions or files here to build your workflow'.
Add 'Extract PDF text', set the desired option, Rich text will include some of the styling, or use plain text.
Eventually it should look like this…
Note: image from 10.9.
Save this as application as 'PDF to Text' on your Desktop. Drag any PDF's onto & it will create a TextEdit document for reading.
There are other potential options in Automator, such as the 'Quartz filters', which may be able to make the PDF black & white & if you tweak the brightness it may be more legible.
You can also make a 'Service' instead of an Application that can run on a right click in certain menus or from the 'Application Name > Service' menu, Automator gives you a lot of power if you take a few minutes to plug things together.

Yup Automator is pretty neat.
If you get stuck post to the Mac OS technologies, you'll get better help on this topic over there. Post a link here & I may follow you over there 🙂
Good luck with it.
Why to you suppose he doest that? Why don't you ask him to make the change. Then he may explain it to you.
Because he likes the color orange and it looks better with a black background when presenting to the class compared to having a white background.
Thank you so much! Automator is amazing!
Drew, I just want to say this is a very nice solution!
Well done, in my opinion.

Automator has some nice tricks hidden up it's sleeve.
