Function Documentation

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

Parse Kalles Fraktaler .kfr file format.

File format example:

Re: -0.75
Im: 0.0
Zoom: 1E0

Line endings are typically CRLF as Kalles Fraktaler is a Windows program. The zoom field $z$ contains a number that gets larger as you zoom in, but it is easy enough to convert to a radius $r$: $r = \frac{2}{z}$. Also, Kalles Fraktaler displays upside down. Rendered images look like they do in Kalles Fraktaler when the imaginary coordinate is inverted, so we do that too.

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).
