As far as comments and annotations within PDF documents, Preview allows font attribute changes per the following table.
Editable | UnEditable |
---|
Text box | Note |
Speech or Thought bubble |
In a previous response, I have shown how to change font attributes in the editable annotations. If you need to add a note to selected text, make it an empty note (kick the Noteworthy font to the curb) and resign yourself to post-processing within the Comments section of Adobe Acrobat Reader XI. The latter application allows you to change the note created in Preview to any font/attribute you desire, and in the note properties, you can even change the icon style and color. Adobe apparently believes that the audience for Note annotations has risen above the fourth grade.
I know how to change the Preview default font and size from the command line, but there is no access to changing the default Noteworthy (not-worthy) font in the Note annotation. In the Notes application, you can change Noteworthy to Helvetica from within the application. I did this, on the wag that Preview might get the hint too. Nope. The Notes application uses a language specific DefaultFonts.plist file, to which a courageous person can add available fonts to the application. Not so, in Preview. You cannot disable Noteworthy in Font Book, because it is a system font. Deleting this system font file is inadvisable.
