How LaTeX writes PDFs
- • pdfTeX embeds Type1 fonts such as Computer Modern.
- • Kerning and ligatures are written into each line.
- • Equations are built from many small pieces.
What that means when you compare two versions
- • Body text and headings edit well; kerning is preserved around your change. Equations are best changed in the source and recompiled.
What happens to the rest of the page
- • The differences between the two files are highlighted.
- • Useful before sending a revised draft.
Questions people ask
+Do I need both files?
Yes. Add the old and the new version to compare them.
+Is it better to edit in LaTeX?
If you have the original LaTeX file and a lot to change, yes. For quick changes to the PDF itself, editing the PDF is faster and keeps it exactly as sent.
