You can use commands under the [Tools] menu to export the current game or all games in the current filter to a text file.
Three text file formats are available: PGN (portable game notation), HTML (for web pages) and LaTeX (a popular typesetting system).
When exporting, you can choose to create a new file, or add the games to an existing file of games exported by Scid.
When exporting in HTML or LaTeX format, Scid will automatically add a diagram wherever a diagram nag ("D") or a comment that starts with the character "#" appears in the game.
Scid can export games to an HTML file. For diagrams to appear, you will need the diagram images (distributed with Scid in the directory "bitmaps/") to be in a subdirectory bitmaps/ under the directory the HTML file is in.
Scid can export games to a LaTeX file. Games be printed two columns to a page and moves are in figurine algebraic notation.
See the Using LaTeX with Scid help page for more information.
