\ttt
Each transformation expands to <box> (\string\hbox\ in most cases).\par
Each transformation must be followed by a <box>.\bigskip
<box> states for any kind of \TeX\ box; \string\hbox,
\string\vbox,
\string\vtop,
\string\box,
\string\copy\par
<trans> is a list of box transformations \par
<dimexpr> states for dimen in eTeX form \par
<numexpr> states for integer in eTeX form \par
<angle> is an integer or float-like string \par
<gsspec> is a literal pdf content stream \par
<paintop> means pdf painting operator (S, f, B, W...)\par
\bigskip
Some extra macros:\par
\def\type#1{{\detokenize{#1}}}
\type{\tobp{<dimexpr>}} returns PDF dimen (big points with no unit) \par
\type{\enablebpround} makes \type{\tobp} rounding to \type{\pdfdecimaldigits} (equivalent to \type{\roundbp}) \par
\type{\setbpround{<0..4>}} makes \type{\tobp} rounding to <0..4> digits (equivalent to \type{\roundbpto{<0..4>}}) \par
\type{\disablebpround} turns off rounding (equivalent to \type{\asbp}) \par
\bigskip
