xod | visual programming language

We are using PdfTron to convert a PDF to XOD so that it can be viewed in XPS viewer. PDFTron is deployed on PCF and used as a service.

Encountered a case when a simple scanned pdf file(5mb), on which OCR is already performed, is taking a huge amount of RAM(5.5GB) while converting it to XOD. We are using following configuration to convert it in java:

I have configured my existing Ionic app as a PWA using workbox. All seems to work fine in Firefox. However in Chrome, both on Windows 10 and Android, a number of font files are not found in the cache.

I have verified that those files do exist in the cache:

Does anyone have any idea what is going on? Why can't the files be found in the cache? The result is that my toolbar icons appear as empty rectangles.

My service worker code is very simple:

I am using WebViewer 2.2.2 and trying to show on an ASP.NET MVC 5 view an XOD file stored in Azure Blob storage, url as : https://somename.blob.core.windows.net/containername/GettingsStarted.xod

I get a CORS error in browser console as "CORS not enabled or no matching rule found for this request."

I found the URL https://www.pdftron.com/webviewer/demo/tutorials/xdomain.html to enable CORS. What URL should I provide in proxy.html file as every XOD blob stored in Azure BLOB storage would have a differenert URL.

The portion https://somename.blob.core.windows.net/containername/ would be same but the filename would be different for dirrerent XOD's. So, how can I pass the XOD filename in the proxy.html file?

Is this the correct way to handle the CORS issue https://www.pdftron.com/webviewer/demo/tutorials/xdomain.html or is there another simpler way?

I have a PDFTron Web Viewer control on my ASP.NET page where I can successfully view a static file 'GettingStarted.xod' already provided by PDFTron in the WebViewer folder. The file is returned by a ASP.NET web api REST service. The file displays successfully while running the solution locally. On hosting in Azure, I get the document from the web api successfully but the web page hosting the web viewer doesn't show the file, instead an empty web viewer control is only displayed. Please suggest how can I get the XOD to be displayed in the ASP.NET page hosting the web viewer control. The code for fetching the XOD file in settings.js file on WebViewer directory is as follows:-

PDFTron XOD Viewer not loading XOD File on ASP.NET Core MVC 6 Razor View. Checking the browser console displays error : "Browser Link: Failed to invoke return value callback: TypeError: Unable to get property 'files' of undefined or null reference".

The browser displays message : "Please" in place of the WebViewer control. I see that this comes from PDFTron WebViewer.js file from the code section as below:

PDFTron Web Viewer not displayed on ASP.NET Razor View on using @model. I receive a HTTP 404 - Not Found error. Without using @model, and in the Controller removing return View(doc); and using return View(); the PDFTron Web Viewer displays the XOD document but on using @model the XOD Viewer is not displayed.

Razor View is as follows. Removing the @model XODViewer.DataModel.Document and changing return View(doc); to return View(); makes it work. I need to bind the View to the model class to access the properties of my model on the View.

Does PDFTron not support displaying the Web Viewer control on MVC Razor View bound to a model?

I have a web api controller GET api method in which I call an external REST service to fetch data. I want to show a piece of data (a property from my data model class to hold the external web service data) on asp.net page. The api controller calls a method of a repository class library where I fetch the data from the external REST service and return in my web api controller.

I call my web api contoller get api method in a javascript on the ASP.NET page where I use the PDF Tron web viewer control.

Uisng PDFTron Web Viewer in ASP.NET or HTML page to display PDF or XOD file, I receive the error as - "Failed to load resource file. This could be due to an incorrect worker path or unsupported .res mime type on the server."

Using the Android sample in the WebViewer folder I have an application in Android Studio which when run on my device works and displays the xod file given as expected. However I've tried to change the lines:
