Problem rendering ejSignature in a modal (bad quality)

[Paul Kocher]

Hi!

It's a bit strange but when I render the signature control in a modal, the quality is really bad. Like this:

When I resize any element of the browser (I noticed when I reduced the size of the dev tools in Chrome) the quality is ok. Like this:

I tried to resize the control using jquery but this didn't quite work. Any idea how I could fix that?

Hi Paul Kocher,    

    

Thanks for contacting Syncfusion support.    

Based on the shared images, we can able to found that the signature div container have been changed programmatically in the Modal Dialog . Hence this will change only the width of signature’s canvas not element’s height and width. And this will also lead to signature drawing misplacement and also the less image quality. So, we suggest you to refresh the Signature canvas element after the control is rendered. This refresh can be called in the modal Dialog open event or any of the page event. 

 

 

   function onopen(e) { 

      

        obj = $("#mysign").ejSignature("instance"); 

        obj._resizeCanvas();  

 

    } 

 

  

Please use this private _resizeCanvas() internal function as of now to refresh the Signature. we have also logged a defect report to provide the “refresh ”as a public method and created a support incident to track the status of this defect has been created under your account. Please log on to our support website to check for further updates.
