.SH NAME
qfractalnow \- Explore fractals and generate fractal images.
.SH SYNOPSYS
.B qfractalnow
[OPTIONS]
.SH DESCRIPTION
QFractalNow is a graphical tool, based on Qt library, that allows users to
explore fractals intuitively and generate pictures.
.br
It is multi-threaded and implements advanced algorithms and heuristics that
make computation very fast compared to most existing free fractal generators.
.br
See FractalNow, a command-line tool to generate fractal images.

Specify precision of Multiple Precision (MP) floats (see help for default value).
.
.TP
.B \-a <AntiAliasingMethod> 
Specify anti-aliasing method:
.RS
none          By default.
.br
blur          Gaussian blur.

.RE
.
.TP
.B \-m <MinAAMSize>
Specify minimum size of adaptive anti-aliasing (see help for default value).
.br
Must be an integer strictly greater than 1.
.
.TP
.B \-M <MaxAAMSize>
Specify maximum size of adaptive anti-aliasing (see help for default value).
.br
Must be an integer strictly greater than 1 and MinAAMSize.
.
.TP
.B \-n <AAMSizeIteration>
Anti-aliasing size iteration.
.br
Anti-aliasing size will increase by steps of AAMSizeIteration from MinAAMSize to MaxAAMSize.
.
.TP
.B \-p <AAMThreshold>
Threshold for adaptive anti-aliasing (see help for default value).
.
.TP
.B \-i <QuadSize>
Maximum size of quadrilaterals for linear interpolation.
.RS
Default is good for no visible loss of quality (see help for default value).
.br
1 means no interpolation (all pixels are computed).
.RE
.
.TP
.B \-t <Threshold>
Dissimilarity threshold for quad interpolation.
.RS
Default is good for no visible loss of quality (see help for default value).
.br
A quadrilateral that shows too dissimilar values at its corners will be computed, 
as opposed to interpolated.
