How to set a image for a form field?

Can pdf-lib be used to programmatically fill form field with a image in a template PDF I tried like this,but failed

const sigAppearanceStream = PDFContentStream.of(   
  PDFDictionary.from({
    Type: PDFName.from('XObject'),
    Subtype: PDFName.from('Form'),
    BBox: PDFArray.fromArray([
      PDFNumber.fromNumber(0),
      PDFNumber.fromNumber(0),
      PDFNumber.fromNumber(200),
      PDFNumber.fromNumber(50),
    ], pdfDoc.index),
    Resources: PDFDictionary.from({
      XObject: PDFDictionary.from({}, pdfDoc.index)
    }, pdfDoc.index),
  }, pdfDoc.index),
    drawImage('MarioEmblem', {
      x: 447,
      y: 520,
      width: marioEmblemDims.width * 0.75,
      height: marioEmblemDims.height * 0.75,
    }),
);

@FilipeAraujo I do plan to greatly improve pdf-lib’s support for signatures and acroform fields. I’m currently working on finishing v1.0.0, which includes a new high level API for pdf-lib’s existing features. After that, one of the things I’d like to work on is better acroform and signature support. I can’t commit to a specific timeline. But hopefully it’ll be done within a few months.

@ConandSherry thanks! however, would it be great to do this without changing the pdf-lib core. @Hopding do you have something in the pipeline related to this? thanks!
