@mwilliamson

please suggest if any other way @mwilliamson to solve this

Hi Please suggest if any update . Or suggest any way if i can achieve this

Hi Friends,

We can set image width and height by image option. But it apply on all image.

Hi williamson,
I am using your mammoth plugin for docx to html conversion, everything is fine but I am not able retain the width and height of the image kindly suggest any method for this.
Thank You.

This code is working:

mammoth.convertToHtml(
            { arrayBuffer },
            {
              convertImage: mammoth.images.imgElement((image) => {
                return image.read('base64').then((imageBuffer) => {
                  return {
                    src: 'data:' + image.contentType + ';base64,' + imageBuffer,
                    style: 'max-width: 100%',
                  };
                });
              }),
            },
          );

Hi @mwilliamson,

do you maybe have any updates on this? This is the last missing requirement for us to test your library in production.

It would be great to get the size (width and height) that images have within the Word file.

const options = {
  convertImage: mammoth.images.imgElement(async image => {
    return {
      src: // ...
      width: image.width + "mm",  // <-- get image width (maybe as px, pt or mm meisure unit)
      height: image.height + "mm"  // <-- get image height (maybe as px, pt or mm meisure unit)
    };
  })
}

I have attached a Word file, where I added an image that I resized.

No particular updates, and I've just finished my week off work so I have no idea when I'll have time to look at this, I'm afraid.

@mwilliamson

Thank you for your quick reply again @mwilliamson. Hopefully a solution is possible in the near future.

This should be a matter of parsing wp:extent or pic:spPr.a:xfrm.a:ext and grabbing its cx and cy for image width and height, respectively.

Just note that DOCX doesn't preserve the original image dimensions. We can get them from the image buffer, but it depends how Mammoth works (I'm just learning the ropes). I would love to have the resized image dimensions exposed from the parser. If I can figure out this package, I will open a pull request.

@mwilliamson

A solution would be really great. Any updates on this one @mwilliamson?

Nope, no updates.

@mwilliamson

Opened an extremely rough pull request at #445. Would appreciate some guidance and discussion around the implementation in there, @mwilliamson. I see your PR description says new PRs are generally not accepted. I hope we can still discuss and ship this together. I would appreciate your help a ton!

This would be a great addition to Mammoth. Would it be possible to accept this PR?

Note that this pull request still needs some work to be done before it can be merged. I would appreciate if we gave Michael enough time to look into this and don't bump this issue until then. You can also sponsor his work because it's extremely time-consuming to be maintaining a widely-used project. Thanks.

Thanks for the info @kettanaito, I can imagine. Thanks for the link, I (or my start-up) will donate some money this week.

I'm afraid I'm still not accepting pull requests, although if you have minimal example documents from the sources you mentioned (Microsoft, Google Docs, Apple Pages), then they would be helpful to include in this issue.

What will be the best way to share them here?

Also, I'm new joining to the project, is there anywhere I can read about your stance of not accepting PRs? What does that mean for the project's development? Is this an actively maintained project?

I am in a dire need of a good DOCX parser. I've written one myself and it does 90% of what I need but that 10% is tricky. Mammoth nails those 10% well (but has some gaps in other areas, image dimensions being one of them). Waiting isn't part of my development culture so I'd like to know how much I can rely on this library! Thanks.

You should be able to upload the files as part of a comment.

It's generally more work to accept pull requests, especially given there are multiple implementations, than it is just to do the work myself.

What does that mean for the project's development?

It means the project is dependent on when I get the time and motivation to work on it, which is not much in the last few years.

Is this an actively maintained project?

It's actively maintained in that I'll try to address bugs and occasionally add support where it seems useful and in keeping with the philosophy of the project, but I wouldn't expect any significant additions at this point.

If waiting isn't part of your development culture, and Mammoth doesn't already broadly cover what you need, then I'd suggest you shouldn't rely on this library.

Really appreciate the response!
