svg2pts

Command line utility to convert the paths in a SVG to a list of points. All paths in the SVG are converted into a list of points with curve interpolation is controlled by command line arguments. Paths with no stroke nor fill are ignored. Output is a sequence of points, X Y\n

Installation

Using snaps:

snap install svg2pts

Using cargo:

cargo install svg2pts

OR with enabled text feature, requires harfbuzz,

cargo install svg2pts --features=text

This will make the svg2pts binary available in your cargo binary directory; usually ~/.cargo/bin.

Usage

svg2pts 0.1.5
Converts all paths in a svg to a list of points. Paths
with no stroke nor fill are ignored. Output is a sequence of points, `X Y\n`. 

USAGE:
    svg2pts [OPTIONS] [ <input> [<output>] ]

FLAGS:
    -h, --help       Prints help information

OPTIONS:
    -a, --accuracy <accuracy>    Set tolerance threshold for bezier curve approximation, 
                                 lower -> higher quality [default: min(<distance>/25.0,0.05)]
    -d, --distance <distance>    Set target distance between points, depends on DPI of SVG.
                                 If distance == 0.0 point distance not normalized.
                                 [default: 0.0]

ARGS:
    <input>     Input SVG file, stdin if not present
    <output>    Output file, stdout if not present"#

Changelog

  • v0.1.5
    • Fix: Commandline argument, output file bug.
    • Change: Lower tolerance threshold for improved default accuracy and scale threshold for small distances.
  • v0.1.4
    • Make text support an optional feature, making the harfbuzz dependency optional.
  • v0.1.3
    • Improved distance normalization: The points generated more accurately follow the paths in the SVG at a variety of distance parameters.
    • Hidden path removal: Paths which have no stroke nor fill value are ignored when generating points.
  • v0.1.2
    • Transformations now applied: Previously path transformations where ignored.
