Export PDF pages to separate jpg?

[Michael Lambert]

I'd like to export all pages of a PDF file to separate image files (one image file per page).  Can I do this with the PDFViewer or PDF Framework?  I don't need to view the PDF, just take a file and convert it to individual image file per page.

Thanks,

Mike

Hi Mike,

Kindly Refer the below UG documentation for your requirement. PDF Viewer allows to save each page into separate image files.

UG documentation - https://ej2.syncfusion.com/aspnetcore/documentation/pdfviewer/how-to/export-as-image

NOTE: You can refer to the below link where you can convert a PDF document into images, using Syncfusion PDF Viewer.

Sorry for the late reply, got busy on other things.  That example is for .net core, I'm using Blazor.  I got the following to work in Blazor Server:

            PdfLoadedDocument loadedDocument = new PdfLoadedDocument(bFile);

            for (int i = 0; i <loadedDocument.PageCount; i++)

            {

                PdfPageBase pageBase = loadedDocument.Pages[i];

                var extractedImages = pageBase.ExtractImages();

                if (extractedImages is not null && extractedImages.Count() > 0)

                {

                    img.Add(ConvertImageToBytes(extractedImages[0]));

                }

            }

            loadedDocument.Close(true);

But when I migrate it to Blazor WebAssembly I get any error on this line:

   var extractedImages = pageBase.ExtractImages();

Error: System.Drawing is not supported on this platform.

How would I migrate some like what is above to WebAssembly?

Thanks,

Mike

Hi Michael,

We can extract the image from existing PDF document by using ExtractImages API. To extract the image from PDF document in .NET 6, we need to install the Syncfusion.Pdf.Imaging.NET package in your application. We have created a .NET 6 Blazor client sample for extracting the images an existing PDF document using the Syncfusion.Pdf.Imaging.NET package and attached the sample for your reference. Kindly please run the below sample on your end with your input document and let us know the result.

So, the example you provided was just the same code I poste;) It works fine with Blazor Client, BUT NOT BLAZOR WEBASSEMBLY!

Is there any way to extract images from PDF pages on the client using WebAssembly?  I currently worked around it by sending the PDF file off to a controller to do the processing.  It works, but I'd rather do all the processing on the client instead of sending it off to the server then sending it back to the client.

Thanks,

Mike
