Displaying a PDF thumbnail is iOS (and Android)

[James Roome]

Hi there,

In my application the user has downloaded some PDFs and I want to show them a thumbnail preview of the 1st page of the PDF.

I've dug around in the API and can't figure it out :(

Any help would be great! :)

Hi James, 

 

At present we do not have “support for converting PDF pages to Images in Xamarin platform”. A support incident to track the status of this implementation has been created under your account. Please log on to our support website to check for further updates

However we have created a workaround for converting PDF pages to images in Windows Azure service and it is available in the below knowledge base link:

Hi, is this possible yet (preferably for Xamarin Forms, not just iOS)? We'd like to convert a PDF page to a full-size image (i.e. not a thumbnail). 

This page (https://www.syncfusion.com/products/file-formats/pdf which I got to from https://www.syncfusion.com/products/xamarin/pdf) seems to suggest you can (see PDF to Image under Conversion) but I can't seem to find anything in the documentation.

Hi James,  

At present, PDF viewer does not support converting PDF pages to images. We have already logged a feature request for the implementation of the support. The feature request can be tracked through our Feature Management System below.

However, PDF pages can be converted to images using native PDF rendering APIs in each platform. PDF viewer too uses native rendering engine to render the pages of the PDF document.  

Please refer to the answer provided in the below forum.

Please let us know if you have any concerns on this.
