ASP.NET Core and Conversion to PDF

Asked On August 31, 2017 01:06 PM UTC

If I understand your Conceptual Overview Diagram for DocIO, the conversion of doc to PDF is not supported yet in ASP.NET Core version of DocIO (whilst it appears that XlsIO already supports xls conversion into PDF).

Two questions:
1) can DocIO of ASP.NET Core convert output doc file into PDF
2) if not, when will this be supported?

Thank you

Hi Zoran,

Thank you for using Syncfusion product.

1. Can DocIO of ASP.NET Core convert output doc file into PDF
DocIO uses the System.Drawing and GDI functionality for Word to PDF conversion. Since the unavailability of this functionality in ASP.NET Core, currently DocIO does not have support for direct Word to PDF conversion in ASP.NET Core.

2. If not, when will this be supported?
We are currently analyzing the feasibilities to implement this feature in our upcoming release. At this moment, we cannot provide any concrete timeline for this feature.

Alternative approach:
Alternatively, service can be used to convert Word document as PDF and then that service can be referred in the ASP.NET Core application.

We have prepared a sample to meet your requirement and in this sample, we have done the following things.
In ASP.NET Core sample,
     1. Loads the existing Word document.
     2. Send input Word document as stream to Web API (service) application.
In ASP.NET Web API (service),
     3. In service side, gets stream (input document), converted it into PDF, and return the response with resultant PDF.
     4. In core side, received the PDF stream and return as PDF file.

Please find the samples which illustrates the same from below link, and let us know if this helps you.
ASP.NET Core sample application:

ASP.NET Web API (service) application:

Steps to follow:
1. Run the ASP.NET Web API service application.
2. Run the ASP.NET Core Web application which referring the service link on it.

Hi Ajay,

Thank you for your update.

Regarding Word to PDF conversion support in ASP.NET Core:
We regret to let you know that the support for “Word to PDF conversion in ASP.NET Core” is not yet implemented. As we mentioned in our previous update, currently Essential DocIO uses the System.Drawing functionality in Word to PDF conversion which is unavailable at ASP.NET Core.

On further analysis, we have found the possible ways to overcome the limitation in font measuring. Currently, we are analyzing the feasibility to overcome the font embedding limitations in Word to PDF conversion. Once we find the solution for this limitation, we will include this feature immediately in ASP.NET Core.

At this moment, we cannot provide any concrete timeline for this feature. We will let you know once this feature has been implemented.

Please let us know if you have any other questions.
