The specified font value shall match a resource name in the <b>Font</b> entry of the default resource dictionary (referenced from the <b>DR</b> entry of the interactive form dictionary; see "Table 224 — Entries in the interactive form dictionary"). A zero value for <i>size</i> means that the font shall be <i>auto-sized</i>: its size shall be computed as an implementation dependent function.

+The default appearance <ins onMouseEnter="mouseEnter(this)" data-issue="318">byte</ins> string shall contain at most one <b>Tm</b> (text matrix) operator.

If the default appearance <ins onMouseEnter="mouseEnter(this)" data-issue="318">byte</ins> string contains no <b>Tm</b> operator, the viewer shall insert one in the appearance stream (with appropriate horizontal and vertical translation components) after the default appearance string and before the text-positioning and text-showing operators for the variable text.
