Hi Guys could you supply me with an Asp Net Core Razor page example where you convert a multi page pdf invoice into multiple images .
Thanks
Edmund Herbert
Using the PDF to image converter library, you can convert PDF documents into images. This allows you to convert multiple PDF pages into individual images. We have attached a code snippet and a sample below for your reference.
|
//Initialize PDF to Image converter. PdfToImageConverter imageConverter = new PdfToImageConverter(); //Load the PDF document as a stream FileStream inputStream = new FileStream("Input.pdf", FileMode.Open, FileAccess.ReadWrite); imageConverter.Load(inputStream); //Convert PDF to Image. Stream[] outputStream = imageConverter.Convert(0, imageConverter.PageCount - 1, false, false); |
Hi thanks could you show me how to save multiple images from stream extracted from pdf with multiple pages also how images could be saved to reflect each page.
Regards

Hi Edmund,
We can save the resulting `stream[]` as multiple images using the code snippet and sample we have attached below. By combining all the images into a ZIP file, we enable the downloading of that ZIP file.
|
using (MemoryStream ms = new MemoryStream()) { ms.Position = 0; //required: using System.IO.Compression; using (var zip = new System.IO.Compression.ZipArchive(ms, ZipArchiveMode.Create, true)) { for (int i = 0; i < imageStream.Length; i++) { var entry = zip.CreateEntry("Page" + i +".png");
using (var entryStream = entry.Open()) { imageStream[i].Position= 0; imageStream[i].CopyTo(entryStream); } } } return File(ms.ToArray(), "application/zip", zipName); } |
