Not working with pixel dimensions

[yul]

Hello, thanks for sharing this project. I am trying to use this lib for my project, and while micro service version works correct, this lib does not work for the same SVG.
SVG in question is this:

<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="5595" height="5842" viewBox="0 0 5595 5842">
<path d="M 10.423511 5.6126619 H 145.39461"
      style="stroke: rgb(204,204,0); stroke-width: 5; stroke-dasharray: none; stroke-linecap: round; stroke-linejoin: miter; stroke-miterlimit: 4; fill: none; fill-rule: nonzero; opacity: 1;"
      transform="translate(1460.24 1311.29) scale(3.78 3.78) translate(-77.90906050000001, -5.6126619) "
      stroke-linecap="round"/>
<ellipse cx="0" cy="0" rx="16.5" ry="16.5"
         style="stroke: rgb(204,204,0); stroke-width: 5; stroke-dasharray: none; stroke-linecap: butt; stroke-linejoin: miter; stroke-miterlimit: 4; fill: none; fill-rule: nonzero; opacity: 1;"
         transform="translate(419.37 165.71) rotate(90)"/>
<line x1="0" y1="-37.5" x2="0" y2="37.5"
      style="stroke: rgb(204,204,0); stroke-width: 5; stroke-dasharray: none; stroke-linecap: butt; stroke-linejoin: miter; stroke-miterlimit: 4; fill: rgb(0,0,0); fill-rule: nonzero; opacity: 1;"
      transform="translate(119.5 362.11) scale(1 0.99)"/>
<line x1="0" y1="-37.5" x2="0" y2="37.5"
      style="stroke: rgb(204,204,0); stroke-width: 5; stroke-dasharray: none; stroke-linecap: butt; stroke-linejoin: miter; stroke-miterlimit: 4; fill: rgb(0,0,0); fill-rule: nonzero; opacity: 1;"
      transform="translate(447 361.61) scale(1 0.99)"/>
<line x1="0" y1="-37.5" x2="0" y2="37.5"
      style="stroke: rgb(204,204,0); stroke-width: 5; stroke-dasharray: none; stroke-linecap: butt; stroke-linejoin: miter; stroke-miterlimit: 4; fill: rgb(0,0,0); fill-rule: nonzero; opacity: 1;"
      transform="translate(282.99 399.6) rotate(90.07) scale(1 4.42)"/>

The source of problems is the first line with dimensions in pixels. When dimensions are in mm, it works, but it converts them to pixels somehow.

Most recent version of the lib returns this error:

Error: w and h must be numbers

I have tried this:

• change version in package.json to 0.2.3
• copy https://github.com/elrumordelaluz/micro-outline-stroke/blob/master/yarn.lock to project dir
• run yarn

to install the same libraries versions (not sure if I did all correct, though)

result is just a bit different

TypeError: Cannot read property 'bitmap' of undefined

at the same time microservice at https://micro-outline-stroke.now.sh/ returns result correctly.

I'm not sure where to search for the problem, can you give me any advice on this?

@yul sorry for the late reply, trying your code here https://outline-stroke.vercel.app/ I am getting this result:

Please let me know if this is correct or not.
Thank you,

update after read more detailed

Will investigate directly with the lib instead. Will come back to you asap.
