bool	parse_mdz_corners (const char *source, int length, mpfr_t cx, mpfr_t cy, mpfr_t cz)
	Parse MDZ .mdz file format (corners variant).

Function Documentation

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

Parse MDZ .mdz file format (corners variant).

File format example:

precision 80
aspect 1.33333
xmin -2.5
xmax 1.5
ymax 1.5

Converting from corners is tricky, but luckily .mdz specifies the precision needed so we don't have to guess it. Then:

cz = (xmax - xmin) / (2 * aspect)
cx = (xmax + xmin) / 2
cy = (ymax - cz)

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).
