◆ compile_pdf()

std::string line::io::tikz_detail::compile_pdf	(	const std::string &	tex,
		const util::TempDir &	dir )

inline

exportToPDF: compile tex in a fresh directory and return the PDF path.

The directory belongs to dir, so the caller copies the PDF out before it goes.

◆ java_fixed()

std::string line::io::tikz_detail::java_fixed	(	double	v,
		int	prec )

inline

Java's String.format("%." + prec + "f", v).

The digits are the shortest decimal expansion that reads back as v (what Double.toString prints), rounded half up at prec decimals, which is FormattedFloatingDecimal.applyPrecision. A negative value keeps its sign even when it rounds to zero, as Java's does ("-0.00").
