Flexible Line Spacing

By default, the paragraph line spacing is fixed to the value of the line-spacing characteristic. To allow flexible line spacing so that, for example, you can include inline graphics that are larger than the line spacing, set the min-leading characteristic to something other than its default value of #f. A useful value for min-leading is the same value as the line-spacing characteristic.

Use min-leading in a style specification, in a paragraph flow object, or where the characteristic will be inherited by a paragraph flow object.
