Specifies the way to determine the spacing between lines in a paragraph
The line spacing can be greater than or equal to, but never less than, the specified Paragraph.LineSpacing value.
This option is twice that of single line spacing.
This option sets fixed line spacing, specified by the Paragraph.LineSpacing property.
This option sets line spacing that can be expressed in numbers greater than 1. For example, setting line spacing to 1.15 will increase the space by 15 percent, and setting line spacing to 3 increases the space by 300 percent (triple spacing). The multiplication value is specified by the Paragraph.LineSpacingMultiplier property.
This option is one-and-one-half times that of single line spacing.
This option accommodates the largest font in that line, plus a small amount of extra space. The amount of extra space varies depending on the font that is used.
