Create a custom signature pad in PdfViewer ?

Hello,

It is possible to create a custom signature pad instead of the built-in signature pad ? 

I was trying to make a signature pad with the sfImageEditor, and saving the signature as image and then place it as a stamp in the PdfViewer control but the image used as a stamp as a white background color. The final render isn't correct in this case. 

Thank you in advance

Hi, 

I checked your sample but the background of the "custom stamp" is still white, not transparent. 

I probably misunderstood your first answer, the custom stamp was preserved, howewer I couldn't set a transparent background on this custom stamp/image. 


But, I think the requested feature as already been added :

Hi Rayhane,  
 
At present, we do not have the support to change the background color of the Image obtained from the SfImageEditor control. We have already added the feature request for erasing the free hand drawing support in the image editor along with that we have considered your feature request to modify the background of an image in image editor .You can track the status of the feature from the below link.  
   
   
Please cast your vote to make it count. We will prioritize the features every release based on the demands and we do not have an immediate plan to implement this feature since we committed with already planned work. So, this feature will be available any of our upcoming release.   
   
If you have any more specification/suggestions to the feature request, you can add it as a comment in the portal.  
 
Regards, 
Ashok Kumar Viswanathan.
