I have the same problem, signatures that doesn't display in the pdf. It's completely blank.

change pdfjs-dist -> pdf.worker.js
/if (data.fieldType === 'Sig') {
_this2.setFlags(_util.AnnotationFlag.HIDDEN);
}/

Any update on this issue?

O have the same problem, is not a problem with vue-pdf is a problem with pdfjs-dist as @bruncelee said. You can do a modification to pdfjs-dist yourself or you can replace the version of pdfjs-dist for the one I have fork on my repo. Hope it helps

I also have this problem and I Comment the file pdfjs-dist/build/pdf.worker.js line 23178 judge the value of data.fieldType and set this.flags=2,and it`s works finally

go to pdfjs-dist/build/pdf.worker.js and with find phrase tool type: 'Unimplemented widget field type'

you should see code like this:

switch (fieldType) {
     case "Tx":
          return new TextWidgetAnnotation(parameters);

     case "Btn":
          return new ButtonWidgetAnnotation(parameters);

     case "Ch":
          return new ChoiceWidgetAnnotation(parameters);
}
(0, _util.warn)(`Unimplemented widget field type "${fieldType}", ` + "falling back to base field type.");

if you don't have case "Sig" (in my case, i didn't had it), you must add it like image widget

switch (fieldType) {
     case "Tx":
          return new TextWidgetAnnotation(parameters);

     case "Btn":
          return new ButtonWidgetAnnotation(parameters);

     case "Ch":
          return new ChoiceWidgetAnnotation(parameters);

     case "Sig":
          return new SquareAnnotation(parameters);
}
(0, _util.warn)(`Unimplemented widget field type "${fieldType}", ` + "falling back to base field type.");

this modify works for me.

this will render signatures like images, just remember if you add/remove packages with npm or yarn, this modify will overwrite, do this before build application
