The samples below show how to render PDF file to BMP image in C# and Visual Basic .NET using Bytescout PDF Renderer SDK.
C#
using System; using Bytescout.PDFRenderer; namespace PDF2BMP { class Program { static void Main(string[] args) { // Create an instance of Bytescout.PDFRenderer.RasterRenderer object and register it. RasterRenderer renderer = new RasterRenderer(); renderer.RegistrationName = "demo"; renderer.RegistrationKey = "demo"; // Load PDF document. renderer.LoadDocumentFromFile("multipage.pdf"); for (int i = 0; i < renderer.GetPageCount(); i++) { // Render first page of the document to BMP image file. renderer.RenderPageToFile(i, RasterOutputFormat.BMP, "image" + i + ".bmp"); } // Open the first output file in default image viewer. System.Diagnostics.Process.Start("image0.bmp"); } } } [/vb] <p><br> <strong>VB.NET</strong></p> [vb]Imports Bytescout.PDFRenderer Class Program Friend Shared Sub Main(args As String()) ' Create an instance of Bytescout.PDFRenderer.RasterRenderer object and register it.
