[Dnhatsave]

Hi everyone,
I like to preview signatures on alfresco share

I follow the instruction and i've coment a part off code

if (this.data.fieldType === 'Sig') { 
	warn('unimplemented annotation type: Widget signature'); 
	return false;
}

of the file components/preview/pdfjs/pdf.worker.js on alfresco share but it dont work.

i like to know how i can achieve the this feature on sinadura?

Don't forget to change pdf.worker-min.js too, and restart Alfresco service.

Kind regards.

Thanks for rapid response @CesarCapillas ,

I don't find the minimal version of the pdf.worker.js

i should change pdf.worker.js for pdf.worker-min.js ??

[CesarCapillas]

Hi:

pdf.worker-min.js is located at the same folder that pdf.worker.js in

/tomcat/webapps/share/components/preview/pdfjs/

It is a minified version of the original javascript, you can copy the changed pdf.worker.js to pdf.worker-min.js first to check everything is working, and later you can minify it with some js tool.

Hope it helps.

Hi cersar,

Im confused, you documentation says

`Configuring Share previews for PDF signatures

In Share AMP, you must extend:

components/preview/pdfjs/pdf.worker.js

commenting this part.

if (this.data.fieldType === 'Sig') { 
	warn('unimplemented annotation type: Widget signature'); 
	return false;
}

`
by default the file pdf.worker.js.old is commented at this line .
what is necessary to preview the signatures?

I've convert the pdf.worker.js to a minified js as you recomend and l've commented the both files
the pdf.worker.js and pdf.worker-min.js on my share amp file.
when i remove this comments the document preview show a infinity loading.

[CesarCapillas]

Hi:

pdf.worker.js.old is just an old reference because it depends on Alfresco Share version.

You must use the pdf.worker.js version for your case and the pdf.worker-min.js minified one, with the corresponding lines commented.

If you find a infinity loading, either you are not using the correct pdf.worker.js version or you minified incorrectly. Surely the minification is the problem, so just copy your commented pdf.worker.js in pdf.worker-min.js preserving both, and deploy for testing. Alfresco Share component is using the minified version.

Be sure too, that maven is not cleaning min files when packaging.

Regards.

Hi cesar,

Now its working :-D, thank you very much for you attention.
I recommend to clarify the Read Me, i thought the pdf.worker.js file was an amp dependency but now i'm sure that is alfresco share dependency.

There is no code :

if (this.data.fieldType === 'Sig') { 
	warn('unimplemented annotation type: Widget signature'); 
	return false;
}

in Alfresco 6.2. Is there something else I need to do in Alfresco 6.2 to see it in the preview?

PS: I can see the sign if it on the first page in the thumbnail.
