Indent and space paragraphs
Indentation specifies the amount of space between text and the bounding box or line that contains the text. Inden-
tation affects only the selected paragraph or paragraphs, so you can easily set different indentations for paragraphs.
• To indent paragraphs, enter a value in the Paragraph panel for an indentation option:
Indents text from the left edge of the paragraph. For vertical text, this option controls the inden-
Indent Left Margin
tation from the top of the paragraph.
Indents text from the right edge of the paragraph. For vertical text, this option controls the
Indent Right Margin
indentation from the bottom of the paragraph.
Indents the first line of text in the paragraph. For horizontal text, the first line indent is relative to
Indent First Line
the left indent; for vertical text, the first line indent is relative to the top indent. To create a first line hanging inden-
tation, enter a negative value.
• To change space above or below paragraphs, enter a value in the Paragraph panel for Space Before
After .
Specify hanging punctuation for Roman fonts
Hanging punctuation controls whether punctuation marks fall inside or outside the margins. If hanging punctuation
is turned on for Roman fonts, then periods, commas, single quotation marks, double quotation marks, apostrophes,
hyphens, em dashes, en dashes, colons, and semicolons appear outside the margins.
❖
Choose Roman Hanging Punctuation from the Paragraph panel menu. A check mark indicates that the option is
selected.
Note: When you use Roman Hanging Punctuation, any double-byte punctuation marks available in Chinese, Japanese,
and Korean fonts in the selected range will not appear outside the margins.
Text composition methods
The appearance of text on the page depends on a complex interaction of processes called text composition. Using the
word spacing, letter spacing, and glyph spacing options you've selected, After Effects evaluates possible line breaks
and chooses the one that best supports the specified parameters.
After Effects offers two composition methods, which you choose from the Paragraph panel menu:
Adobe Single-line Composer
if you prefer to have manual control over how lines break. If spacing must be adjusted, the Single-line Composer first
tries to compress, rather than expand text.
Adobe Every-line Composer
lines in the paragraph in order to eliminate especially unattractive breaks later on. Working with multiple lines of
text results in more even spacing and fewer hyphens. The Every-line Composer approaches composition by identi-
fying possible breakpoints, evaluating them, and assigning a weighted penalty based on these principles:
• Highest importance is given to evenness of letter and word spacing. Possible breakpoints are evaluated and
penalized according to how much they deviate from optimal spacing.
• After breakpoint penalty values are identified for a range of lines, they are squared, magnifying the bad break-
points. The composer then uses the good breakpoints.
Offers a traditional approach to composing text one line at a time. This option is useful
Considers a network of break points for a range of lines and thus can optimize earlier
