signaturepad

问题 I'm trying to understand how I can do a signature capture in React Native. My App is created with create-react-native-app and Expo and I'd prefer to not have to eject the app to get this functionality to work. Would it be possible to wrap something like this in a webview? https://github.com/szimek/signature_pad I've also looked at this project, https://github.com/RepairShopr/react-native-signature-capture but it requires me to eject the app and use react-native link . Looking for any advice

问题 I've been using Thomas J. Bradley's jQuery Signature Pad plugin for capturing drawn signatures and it works well. What I'd like to do is also allow typed signatures as shown in demo but have it output the same data as a drawn signature (JSON representation). Since the data output is actual coordinates of the cursor as it moves over the canvas, I'm guessing it would have to emulate that mouse or touch movement. I found another Stackoverflow answer about drawing text on the canvas. Is there a

问题 I'm using the signature-pad JavaScript library to have people digitally sign documents (this is just for testing, nothing legally binding, etc.) but I'm having a hard time passing the signature result back to Flask/Python from JS. The following code is my HTML form, it submits the form.stu_name field perfectly, and even triggers my JS to "submit"(meaning the code executes and a new window opens displaying the signature) but I'm not sure how to submit the JS result back to Flask - see the

问题 I'm currently working on an Angular2 project and I'm trying to use a JS library (https://github.com/szimek/signature_pad) for signature input. I've tried using the library as is, with my code as follows: // .ts file import * as SignaturePad from 'signature_pad'; export class ... { private signaturePad: SignaturePad; ngOnInit() { let canvas = document.querySelector("canvas"); this.signaturePad = new SignaturePad(canvas); } } . // .html file <div...> <canvas></canvas> </div> and I get the

问题 I am using angular2-signaturepad library to work with signature in my angular project. Here is my code: signature.module.ts import { NgModule } from '@angular/core'; import { IonicPageModule } from 'ionic-angular'; import { SignaturePage } from './signature'; import { SignaturePadModule } from 'angular2-signaturepad'; @NgModule({ declarations: [ AssinarPage, ], imports: [ IonicPageModule.forChild(AssinarPage), SignaturePadModule ], }) export class SignaturePageModule {} signature.ts export

问题 I'm trying to get a Classic ASP version of this app to save images to my server: https://github.com/szimek/signature_pad I've tried various combinations of using the Base64 output but have not had any success. I've searched this site and Googled but haven't been able to find anything that makes sense to me. If anyone has any ideas on how to convert the output from Signature Pad to a server side image I would be very grateful! The JS code is: var wrapper = document.getElementById("signature

问题 As stated in the title I'm trying to upload an image to my S3 bucket with rails' Active Storage from a element that is nested within a rails form. So far I've been able to use <%= f.input :signature, type: file_field(:user, :signature), %> to upload an image with Active Storage. The User class has_one_attached :signature . The images upload correctly when I use a file_field, so that's not part of the problem. So far my simple_form has: <div class="signature_pad text-center form-group"> <div

问题 I'm developing a Xamarin.Forms application with Prism framework in a MVVM architecture. I need to collect the signature from the screen, so I decided to include the SignaturePad library. With NuGet I included Xamarin.Controls.SignaturePad and Xamarin.Controls.SignaturePad.Forms packages. In page layout (built with XAML) I have the signature widget: <signature:SignaturePadView x:Name="padView" HeightRequest="130" CaptionText="Sign" CaptionTextColor="Black" ClearText="Clean" ClearTextColor=
