is PDF to Image conversion available in AspNet Core?

[Troy Walker]

I'm looking here: https://help.syncfusion.com/file-formats/pdf/working-with-document-conversions#converting-pdf-to-image

and see the sample, but not able to add or find the PdfViewer to my project.json, am I missing something?

I would like to be able to parse a PDF page to an image to create thumbnails or large output to PNG of the page.

[Troy Walker]

I think I may now see the limitation...

If I am now understanding things correctly, the Syncfusion for ASP.NET Core does "not" have the PdfViewer library (Syncfusion.PdfViewer.Windows.dll), so that feature is not available. (?)

Is that feature available in the ASP.NET MVC version? 

 If so, would I be able to add that into my AspNetCore Project, and only target windows platform for it by adding the net461 framework dependency?

[Troy Walker]

well.. I've tried numerous things and am totally ignorant here on how to integrate PdfDocumentView() to my project.

I even removed the aspnetcore framework to use only net461, adding:

(14.4.0.20 versions of)

Syncfusion.AspNet.Mvc5

Syncfusion.AspNet.Mvc5.FileFormats

Syncfusion.AspNet.Mvc5.PdfViewer

to no avail, the PdfDocumentView class is completely missing.

[Troy Walker]

hello again :)

so, I have something now working,  and not all capabilities of the PDF are being converted properly.

here is the code I have working now using net461, which your MVC5 (classic) package (version: 14.4.0.15)

PdfDocumentView pdfDoc = new PdfDocumentView();

pdfDoc.Model = new PdfViewerModel();

var docStream = new FileStream("test.pdf", FileMode.Open);

pdfDoc.Model.LoadedDocument = new PdfLoadedDocument(docStream);

Bitmap img = pdfDoc.Model.LoadedDocument.ExportAsImage(0, new SizeF(2550, 3300), 300, 300, false);

img.Save("test.png", ImageFormat.Png);

While the pdf does get converted to high resolution image (png), it does not respect the transparency of objects in the original PDF file.

I have attached the samples from my test.  Am I missing a setting or some other property?  Also, my use of the "model" seems a little hacky, but it was the only way I could get it to work.

Is there an update on the ability to convert PDF to an Image in an .NET Core application please?

[Sabari Anand Senthamarai Kannan]

Hi Mark, 

  

Thank you for using Syncfusion products. 

  

At present we do not provide support for “Converting the PDF document pages to image using the PDF library in .NET Core framework”. The feature requires GDI+ functions under System.Drawing namespace to render the PDF element. At present, The .NET Standard framework does not support GDI+ functions and System.Drawing namespace. However, we are analyzing the alternate ways to implement the above mentioned functions. So this feature may be available in any of our future releases. 

  

Please let us know if you need any further assistance. 

  

Regards, 

Sabari Anand
