Then, loop through all the pages and call the Process() method to render into the stream.Next, create an instance of the PngDevice class.
PDFEXTRACTOR CODE PDF
We can read barcodes from converted PDF pages as PNG images by following the steps given below: It allows converting pages of the PDF document into PNG images. The only difference is that in this method, we will convert the pages of the PDF document into images using the PngDevice class of the API. Here goes another method similar to the previous one. Read Barcodes from PDF using PngDevice in C#
PDFEXTRACTOR CODE HOW TO
The following code example shows how to convert PDF pages into images and read barcodes using C#. Then, create an instance of the BarCodeReader class with the stream object.Next, save the image to stream in a loop.Then, call the DoConvert() method to render selected pages into images.


The BarCodeReader class of the Aspose.BarCode API enables us to perform ReadBarCodes operations to detect barcodes. The ConvertToPNGMemoryStream() function of the API renders a PDF page into a PNG memory stream. The Document class of the Aspose.PDF API represents a PDF document.
PDFEXTRACTOR CODE INSTALL
Please either download the DLL of the API or install it using NuGet. After that, we will read the barcode from the rendered images using the Aspose.BarCode for. NET API to load a PDF document, then we will render its pages to raster images. Firstly, we will be using the Aspose.PDF for. We will follow a two-step procedure to read barcodes from PDF documents. The article shall cover the following topics: In this article, we will learn how to read a barcode from a PDF document using C#. It helps to decode embedded information in the form of barcodes and QR codes from PDF documents such as invoices, receipts, or reports. In certain cases, we may need to detect and read the barcodes embedded into PDF documents programmatically. We can generate and add barcodes to PDF documents as described in my previous post.
