Additional functionality related to this tutorial has been introduced in subsequent versions of

# Text and Font Options

General options for text formatting.

If you have a large block of text containing no explicit newline characters, then

*Mathematica* will automatically break your text into a sequence of lines. The option

PageWidth specifies how long each line should be allowed to be.

WindowWidth | the width of the window on the screen |

PaperWidth | the width of the page as it would be printed |

Infinity | an infinite width (no line breaking) |

n | explicit width given in printer's points |

Settings for the PageWidth option in cells and notebooks.

The option

TextAlignment allows you to specify how you want successive lines of text to be aligned. Since

*Mathematica* normally breaks text only at space or punctuation characters, it is common to end up with lines of different lengths. Normally the variation in lengths will give your text a ragged boundary. But

*Mathematica* allows you to adjust the spaces in successive lines of text so as to make the lines more nearly equal in length. The setting for

TextJustification gives the fraction of extra space which

*Mathematica* is allowed to add.

TextJustification leads to "full justification" in which all complete lines of text are adjusted to be exactly the same length.

Left | aligned on the left |

Right | aligned on the right |

Center | centered |

x | aligned at a position x running from to across the page |

Settings for the TextAlignment option.

TextJustification adjusts word spacing so that both the left and right edges line up.

TextJustification reduces the degree of raggedness, but does not force the left and right edges to be precisely lined up.

When you enter a block of text in a

*Mathematica* notebook,

*Mathematica* will treat any explicit newline characters that you type as paragraph breaks. The option

ParagraphIndent allows you to specify how much you want to indent the first line in each paragraph. By giving a negative setting for

ParagraphIndent, you can make the first line stick out to the left relative to subsequent lines.

LineSpacing->{c,0} | leave space so that the total height of each line is c times the height of its contents |

LineSpacing->{0,n} | make the total height of each line exactly n printer's points |

LineSpacing->{c,n} | make the total height c times the height of the contents plus n printer's points |

ParagraphSpacing->{c,0} | leave an extra space of c times the height of the font before the beginning of each paragraph |

ParagraphSpacing->{0,n} | leave an extra space of exactly n printer's points before the beginning of each paragraph |

ParagraphSpacing->{c,n} | leave an extra space of c times the height of the font plus n printer's points |

Options for spacing between lines of text.

Here is some text with the default setting

LineSpacing, which inserts just 1 printer's point of extra space between successive lines.

Options for fonts.

"Courier" | text like this |

"Times" | text like this |

"Helvetica" | text like this |

Some typical font family names.

Some settings of font options.

*Mathematica* allows you to specify the font that you want to use in considerable detail. Sometimes, however, the particular combination of font families and variations that you request may not be available on your computer system. In such cases,

*Mathematica* will try to find the closest approximation it can. There are various additional options, such as

, that you can set to help

*Mathematica* find an appropriate font. In addition, you can set

FontSubstitutions to be a list of rules that give replacements to try for font family names.

There are a great many fonts available for ordinary text. But for special technical characters, and even for Greek letters, far fewer fonts are available. The

*Mathematica* system includes fonts that were built to support all of the various special characters that are used by

*Mathematica*. There are three versions of these fonts: ordinary (like Times), monospaced (like Courier), and sans serif (like Helvetica).

For a given text font,

*Mathematica* tries to choose the special character font that matches it best. You can help

*Mathematica* to make this choice by giving rules for

and

in the setting for the

FontProperties option. You can also give rules for

to specify explicitly from what font each character is to be taken.
