I have published resvg version 0.3.0

I added a query_all function which return the pos and size of nodes with id.

Resvg.query_all("rustacean.svg")
[
  %Resvg.Native.Node{
    id: "Layer-1",
    x: -63.99300003051758,
    y: 90.14399719238281,
    width: 1304.344970703125,
    height: 613.6170043945312
  }
]

The precompiled nif is now working on windows system.

Hello Kip,

Your work with image, and specifically the use of Operation.svgload_buffer(svg), was a significant source of inspiration while I was developing this library.

I encountered several issues with libvips / vix that led me to try alternative:

1. Windows Support: One of my primary requirements was compatibility with Windows. Unfortunately, as of the time of development, vix did not support it.

2. Font Loading with librsvg: I was unable to successfully get libvips to load my specific font.

3. SVG local file resolution: Another challenge I faced pertained to the svg element <image> in librsvg when resolving local files.

I found resvg to be more compatible with my requirements. Resvg allowed you to specify the :resources_dir, facilitating the resolution of images from this path:

path = "/project/assets/"
svg_string = """
  <svg xmlns="http://www.w3.org/2000/svg" width="400" height="200"
    xmlns:xlink="http://www.w3.org/1999/xlink"
  >
    <image xlink:href="mdn-logo.png" width="200" height="200" />
    <image xlink:href="mdn-logo.png" x="200" width="200" height="200" />
  </svg>
"""
Resvg.svg_string_to_png_buffer(svg_string, resources_dir: path)

Moreover, I found that resvg provided results that closely matched those from the browser. This aspect was particularly important to me as I heavily rely on the browser to create the svg templates and making adjustments.

The :rustler_precompiled nif does not work on windows but the self compiled work. I’m new to rustler and friends. I will try to fix it asap.

Amazing thank you @MRdotB!
The Livebook example needed {:resvg, "~> 0.3"}, to succeed and it got the NIF like charm! Congrats, I’m imagining Windows is not a top priority for the majority of image processors, but you managed to figure it out! Thank you!

If for some reason that’s not possible in revsg you can do it in image with:

"<svg> .....</svg>"
|> Image.from_svg!()
|> Image.write(conn)

Unfortunately the underlying vix isn’t supported on Windows so if that’s a requirement then this isn’t the solution for you. Also it uses librsvg as the svg renderer, not libresvg.
