DrawPad | A simple MS paint-like Android drawing app | Canvas library

When sending an image of a canvas from an iPad or other touch-based device, my canvas-based signature pad does not save the image to the specified directory. Despite the image data sending perfectly fine when testing from Visual Studio and from the live website on a regular Windows PC, the iPad seems incapable of sending the Base64 code through the JavaScript function.

When creating the reprex for this site, I noticed that I needed to comment out a line in RouteConfig.cs (thanks to Sanjay Sharma) before the app was even able to send an image to my local machine. Since then, I tried seeing if there was any sort of redirect issue that would have caused problems when working from the iPad, but I have found nothing to suggest this.

Built as an ASP.NET Web Forms Site (Visual C# > Web > Previous Versions), this page contains a canvas that works with touch and desktop interfaces. The code used to make the canvas (called upon in "Drawpad") is based on the code found here:

I'm having some trouble with using a third-party module called angular2-signaturepad. Using this guide

The guide states that in order to use this module, you have to add SignaturePadModule to the imports section of app.module.ts. However, our project (using Ionic 2) does not have or use an app.module.ts file. All of our dependencies live in our app.ts, specifically our ionicBootstrap function

Since we don't have the app.module.ts file, I decided to add the SignaturePadModule to app.ts

ionicBootstrap(MyApp, [ disableDeprecatedForms(), provideForms(), DataService, UploadService, StorageService, ConnectionService, HTTP_PROVIDERS, ActionSheetController, AlertController, Device, Diagnostic, LoggingService, SettingsService, SnaggingService, **SignaturePadModule**, provide('Storage', { useClass: Storage })] );

I've created a new ts and template files for my page to display the module:
