The Acrobat Reader is a program for reading PDF files, which are designed to ensure that documents can be read on different systems without losing any of their formatting in relation to the original source.
Editing a PDF is almost impossible if you do not have Adobe Acrobat DC, or such a similar application. Most of us have it for free Adobe Reader, which basically allows you to only read PDF files.
Although the program menu is missing all the commands related to it construction, editing, or repairing a document file, the reader still has enough features to be able to read a PDF file to their liking.
Reading these files, which are usually under an all-white background with black letters, is especially tiring at night, especially if you don't have a light on in your room. light.
In addition, there are texts where color combinations are failing and difficult to read. You can change how text appears through the Adobe Acrobat Reader menu to keep up with your preferences. Let's see how.
Open a PDF file (any file) in Adobe Reader. Go to the menu at Edit and then on Preferences (Preferences). In the new window that opens, click the tab Accessibility (Accessibility) and select the option Replace Document Colors (Replacing document colors).
Στη συνέχεια, επιλέξτε του Use High-Contrast Colors (Χρήση χρωμάτων υψηλής αντίθεσης) και επιλέξτε ένα Colour σχεδίου από τις διαθέσιμες προεπιλογές. Αν δεν χρειάζεστε υψηλή χρωματική αντίθεση, αλλά απλά θα θέλατε να κάνετε το έγγραφο ευκολότερο να διαβαστεί με χαμηλό φωτισμό, π.χ. το βράδυ, επιλέξτε το Custom Color (Προσαρμοσμένο χρώμα) αντ ‘αυτού. Στη συνέχεια μπορείτε να επιλέξετε το χρώμα της σελίδαs, and the text of the document, simply inverting the existing selection so that the page color is black, and the text is white.
The only downside is that this will affect all of the documents you open with Adobe Reader, so you will have to reset the initial options when you finish reading at night or reading in better light.
