	Parse MDZ .mdz file format (center variant).

Function Documentation

bool parse_mdz_center	(	const char *	source,
		int	length,
		mpfr_t	cx,
		mpfr_t	cy,
		mpfr_t	cz
	)

Parse MDZ .mdz file format (center variant).

File format example:

aspect 1.77777
cx -0.75
cy 0.0
size 5.33333

Size \(s\) is the real width, convert to radius \(r\) (half imaginary height) by using the aspect \(a\): \(r = \frac{s}{2 a}\). Double precision floating point has enough precision and enough range for any real-world aspect ratio.

Parameters

source	A null-terminated input file already loaded into memory.
length	Length of the input file (without the extra null terminator).
cx	For output of the real part of the view center. It is already mpfr_init2()'d.
cy	For output of the imaginary part of the view center. It is already mpfr_init2()'d.
cz	For output of the view radius. It is already mpfr_init2()'d.

Returns

Success (true) or failure (false).
