PostScript is a page description language run in an interpreter to generate an image, a process requiring many resources. In addition, XFDF does not allow the spawning, or addition, of new pages based on the given data; as can be done when using an FDF file. /Name /F1 and some code (e.g. And more text. And more text. Freeware Qiqqa can create an annotation report that summarizes all the annotations and notes one has made across their library of PDFs. If you know part of the file name or date it was modified, you can narrow your search result and make it quicker and easier. PDF can specify a predefined encoding to use, the font's built-in encoding or provide a lookup table of differences to a predefined or built-in encoding (not recommended with TrueType fonts). There are many software options for creating PDFs, including the PDF printing capabilities built into macOS, iOS,[61] and most Linux distributions, LibreOffice, Microsoft Office 2007 (if updated to SP2) and later,[62] WordPerfect 9, Scribus, numerous PDF print drivers for Microsoft Windows, the pdfTeX typesetting system, the DocBook PDF tools, applications developed around Ghostscript and Adobe Acrobat itself as well as Adobe InDesign, Adobe FrameMaker, Adobe Illustrator, Adobe Photoshop.
