NAME


cfdg - image generator based on context-free grammars

SYNOPSIS


cfdg [options] input.cfdg [output.png/svg]

DESCRIPTION


Context Free is a system that produces images based on context-free grammars. cfdg is the
command-line program to generate the actual images (in PNG or SVG format) from the
input.cfdg file containing these grammars. If - is specified instead of an input file,
the grammar is read from standard input. The output filename can be left out if the -o
option is used. Note that the output mode (PNG or SVG) is not detected depending on the
specified extension, but must be explicitly set using the -V option.

OPTIONS


All command-line options consist of a single letter, and an optional argument. A summary
of options supported by cfdg is included below.

-w width
Set width of the output image in pixels (for PNG) or millimeters (for SVG)
(default: 500).

-h height
Set height of the output image in pixels (for PNG) or millimeters (for SVG)
(default: 500).

-s size
Set both width and height of the output image in pixels (for PNG) or millimeters
(for SVG) to the same value.

-s widthxheight
Set both width and height of the output image in pixels (for PNG) or millimeters
(for SVG).

-T size
Multiply both width and height of the tiled output image by the same amount.

-T widthxheight
Multiply both width and height of the tiled output image by the given amounts.

-m maximum shapes amount
Set the maximum number of shapes rendered (default: no maximum).

-x minimum shape size
Set the minimum size for a shape to be rendered in pixels/mm (default: 0.3).

-b border size
Set the border size: -1 for a -8 pixel border, 0 for no border, 1 for an 8 pixel
border, or 2 for a variable-sized border.

-v variation code
Set the variation code (default: random). This code determines what the final
image will look like when the input contains non-deterministic rules.

-o filename
Set the output filename. In this filename, %f is replaced by the animation frame
number (if any), %v and %V are replaced by the variation code (in lower or upper
case, respectively), and %% is replaced by a literal %.

-a num Generate num animation frames at 15 fps (only possible using PNG output).

-a timexfps
Generate time x fps animation frames at the specified fps (only possible using PNG
output).

-z Zoom out during animation, when producing an animation using -a.

-V Generate SVG (vector) output.

-Q Generate Quicktime movie output (not available in this Debian package).

-c Crop image output.

-q Quiet mode; suppress non-error output.

-C Check the syntax of the cfdg file, then exit.

-t Time output; output the time taken to render the cfdg file.
