[FeatureRequest] Save QRCode to SVG, PDF or EPS as well as PNG #44

Open namsor opened 3 years ago

namsor commented 3 years ago

Hi ! Thanks for this library. It would be nice to be able to save the QRCode to SVG, PDF or EPS as well as PNG.

For example, adding dependency to https://github.com/tdewolff/canvas/ the qrcode.go could have

// Canvas returns the QR Code as an image.Image. func (q QRCode) Canvas() canvas.Canvas { // Based on Image... }

and this can be saved to appropriate format using, c := q.Canvas() c.WriteFile("out.svg", svg.Writer) c.WriteFile("out.pdf", pdf.Writer) c.WriteFile("out.eps", eps.Writer) c.WriteFile("out.png", rasterizer.PNGWriter(3.2))

Attached a draft modification.

Best, E.
