We were checking IWA and we realized that function Appeon saveas Native PDF, doesn't work in IWA. It exports a blank document. We saw that in a Web browser it works. Then we found in the powerserver help that it is unsupported. As it:

NativePDF (*.pdf) -- generates a standard native PDF file. Be aware of the following limitation of the PDF file generated in this way:

NativePDF is unsupported in IWA apps.

PDF (*.pdf) -- prints the page as an image file and then saves the image file as a PDF file. Be aware of the following limitations of the PDF file generated in this way:

The PDF file is not editable and can only be created in a monitor with 32-bit color quality settings or above.

As a workarround, we can choose second option, but users coundn't search in the PDF.

What can we do? Appeon recomend use IWA, better than a web browser, but we are finding limitations... Do you know if appeon will fix this issue?

Hi Juan;

   Correct, as the IWA application is really still a Web App implementation (generated code) from a PowerServer deployment. PS has its own PDF handling scheme. It is not based on the NativePDF feature. So any direct PDF commands will be executed internally as PS (aka jScript) code.

   Now, pushing the IWA App's PDF processing to the server side would now allow NativePDF processing.

FYI: http://chrispollach.blogspot.com/2017/10/pdf.html

Note: The above link shows how to implement this using the PB2017 web service feature. For PB2019, you could also utilize the new C# Web API web service instead as the calling shell

Food for thought.

Regards ... Chris
