Getting Token Error on my Controller

Getting this error  [Error] Error: Compile Error: unexpected token: 'ApexPages.StandardController' at line 3 column 37
I'm trying to add the ApexPages so I can add this VF page via page layout editor.

Thanks,  Paul

public with sharing class CapturePSignatureController {

public CapturePSidnature Controller {ApexPages.StandardController} { 
 
 @RemoteAction
 global static String savePSignature(String imageUrl, String accountId) {
 
  
  try {
   Attachment accSign = new Attachment();
   accSign.ParentID = accountId;
   accSign.Body = EncodingUtil.base64Decode(imageUrl);
   accSign.contentType = 'image/png';
   accSign.Name = 'Patient Signature Image';
   accSign.OwnerId = UserInfo.getUserId();
   insert accSign;
   
   return 'success';
   
  }catch(Exception e){
   system.debug('---------- ' + e.getMessage());
   return JSON.serialize(e.getMessage());
  }
  return null; 
 }

}

Couple of problems with this line:  Sidnature should be Signature, curly brackets should be parentheses around the ApexPages parameter.
public CapturePSidnature Controller {ApexPages.StandardController} { 
Let me know how that works for you.

Changed the curly brackets in {ApexPages.StandardController} { to paentheses and now getting this error
[Error] Error: Compile Error: unexpected token: ')' at line 3 column 69

Thanks for the quick response

This is a parameter declaration right?  So needs a parameter name, not just the type.
Then are you going to use that parameter? Do you need a parameter if you are not using it?

Well,  here is my situation.  I am an SA with a functional background, so my coding skills are not the greatest.  I'm trying to build an E-Signature component for a client of mine that is a non-profit (so pro-bono with no technical developer).  I need an esignature capability on the Case record that I call up as an image via custom print preview. Then have a hardcopy of that Case record printed out.
I am close to having it work, as I can make it all happen in "preview" mode.  Problem is it's a hodge podge of code I've found and I guess my controller needs some work to enable the VF page to be seen/added via standard page editor in SFDC, hence the ApexPages.StandardController problem I'm having since I realized that is why I was not seeing my VF Page through the page editor.

Here is my current controller 
global with sharing class CapturePSignatureController {
 
 
 @RemoteAction
 global static String savePSignature(String imageUrl, String accountId) {
 
  
  try {
   Attachment accSign = new Attachment();
   accSign.ParentID = accountId;
   accSign.Body = EncodingUtil.base64Decode(imageUrl);
   accSign.contentType = 'image/png';
   accSign.Name = 'Patient Signature Image';
   accSign.OwnerId = UserInfo.getUserId();
   insert accSign;
   
   return 'success';
   
  }catch(Exception e){
   system.debug('---------- ' + e.getMessage());
   return JSON.serialize(e.getMessage());
  }
  return null; 
 }

}
Here is my current VF Page Code

instead of controller="CapturePSignatureController"  in your page, define it with the standard controller syntax.  Your controller class can still be accessed as it is fully qualified.  standardController="Account" then it will show up in the Account page layout.  But I thought you said you wanted it to appear on the case?
