isdf
Single-function package which takes an input image.Image and returns an *image.Gray16 Signed Distance Field representation. See example code for simple usage in a command line app.
This code has been adpated from image-sdf.
Usage Example
package main
import (
...
"github.com/vrav/isdf"
)
func main() {
// import an image, decode it if necessary
// see isdf-example.go for an example
...
// convert to 1/4 size SDF image with spread of 32
sdfImage := isdf.ImageToSDF(inputImage, 32.0, 4.0)
// continue on to save the image or use as-is
...
}

Functions ¶
func ImageToSDF ¶
ImageToSDF converts an image using the image.Image interface to its Signed Distance Field representation. Spread affects the width of the distance fields while downscale decreases the resolution of the output image. A downscale value of 2.0 will turn a 512px image to 256px; 4.0 will result in a 128px output image. Converting from a high resolution image to a low resolution image results in better quality.
