These dependencies were not found: * canvas in ./node_modules/pdfh5/js/pdf.js * dommatrix/dist/dommatrix.js in ./node_modules/pdfh5/js/pdf.js, ./node_modules/pdfh5/js/pdf.worker.js * web-streams-polyfill/dist/ponyfill.js in ./node_modules/pdfh5/js/pdf.js, ./node_modules/pdfh5/js/pdf.worker.js

It seems that some dependencies required by PDFH5 are missing. To resolve these dependencies, you can follow these steps:

1. Install missing dependencies: Run the following command in your project's root folder to install the missing dependencies:

   npm install canvas dommatrix web-streams-polyfill

This will install the required packages (`canvas`, `dommatrix`, and `web-streams-polyfill`) and add them to your project's `node_modules` folder.

2. Import the dependencies: In the file `pdf.js` located in `node_modules/pdfh5/js/`, add the following import statements at the top of the file:

   import 'canvas';
   import 'dommatrix/dist/dommatrix.js';
   import 'web-streams-polyfill/dist/ponyfill.js';

Similarly, in the file `pdf.worker.js` located in `node_modules/pdfh5/js/`, add the same import statements at the top of the file.

3. Save the changes and rebuild: After adding the import statements, save the files and rebuild your project. Depending on your build system (Webpack, Rollup, etc.), you might need to run a command like `npm run build` or `npm run dev` to rebuild your project with the updated dependencies.

By following these steps, you should be able to resolve the missing dependencies for PDFH5.
