raster - a convenience package to render vector graphics as images

Overview

The raster package helps visualize vector graphics in the form of a PNG image. It can be used with the "golang.org/x/image/vector" package. Using primatives in that package, the raster package provides support for rendering solid lines and approximate circles. It also provides a convenience function to render the vector paths to an image. Documentation for the raster package should be available on go.dev.

The package provides a simple examples/trace.go program that uses the package to render something resembling a PCB copper trace.

$ go run examples/trace.go --dest image.png

creates the following image.png file:

License info

The raster program is distributed with the same BSD 3-clause license as that used by golang itself.

Reporting bugs and feature requests

The package raster has been developed purely out of curiosity for and as part of a project to create simple PCBs using a Snapmaker 2 3D printer (with laser and CNC tool heads). If you find a bug or want to suggest a feature addition, please use the bug tracker.
