Annotation line tools javascript error - "_super is not defined"

[justin.spencer]

Using pdf.js express plus 8.7. When I try to use these line tools, I get the following exception “_super is not defined.” This error looks like a bug to me as there’s no declaration of _super in the code. Please advise.

See uploaded doc for details.
It fails in webviewer-core.min.js

On (“Custom appearances are unavailable in PDFJS Express.”),_super.prototype.Dh.call(this,Ua);var cb=document.createElement(“canvas”)

There’s no declaration of the variable “_super” anywhere in the code so I’m not surprised it fails.

Hi justin.spencer,

I am unable to reproduce your issue on the demo site (8.7)

PDF.js Viewer Demo | PDF.js Express

or on our sample site:
https://pdfjs.express/samples/viewing/viewing/

Do you have any custom code that you can share here that may affect how your tool is being used?

Hi Kevin, the issue for me appears to be in the exportAnnotations method. Do you have an example available for exports?

(sorry about the image, but it wouldn’t let me post code into the forum)

Hi justin.spencer,

Here is our guide on exportAnnotations:

I wanted to double check if you have the license key configured correctly (no need to provide the code as this is a public forum), as the error message mentions “Custom appearances are unavailable in PDFJS Express.”
Here’s a guide on that: PDF.js Express Viewer Download & Integration | Documentation

Hi,

I am still having the same issue. Can you get someone to look into this. The problem is if you go to shapes and draw a line, polyline, ellipse or arc. Then you call instance.annotManager.exportAnnotations({}) in your code you will get the error bellow.

I have used the information in your guides below and i am still having the same issue Open a document, add annotations, download | Documentation and Importing and exporting annotations | Documentation.

Hi Kevin,
that build looks better for all of the controls except for the arc control. See attached… the arc still generates the same exception.

[sodubanjo]

Hi,

Thanks for this build, It seem the Arc is still throwing this error. Can you look into this please.

Thanks

Hi Kevin, PDFJSExpress-8.7.0-36309.zip looks like the same version you gave me last Friday (and the arc control still has an issue). Did you mean to post a newer link?

[sodubanjo]

Hi

I don’t think there is any changes between this build and the previous one. Can you look into this.

Thanks

Hi Kevin,
much better now thanks. However I’m still getting errors with the arc control when I draw off the side of the page (is this a known issue).

[kkim]

Hi justin.spencer,

Thank you for your report.

It looks like this is a separate issue, as it happens for other tools as well when you click outside of the page. For now, you can simply select the annotation and delete it and exportAnnotation will work as normal.
