The following samples show rendering PDF to PNG image in C# and Visual Basic .NET using PDF Renderer SDK.

C#

[vb]using System;

using Bytescout.PDFRenderer;

namespace PDF2PNG
{
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 PNG image file. renderer.RenderPageToFile(i, RasterOutputFormat.PNG, "image" + i + ".png"); } // Open the first output file in default image viewer. System.Diagnostics.Process.Start("image0.png"); } } } [/vb]

VB.NET

[vb]
Imports Bytescout.PDFRenderer

Class Program
Friend Shared Sub Main(args As String())

‘ Create an instance of Bytescout.PDFRenderer.RasterRenderer object and register it.
Dim renderer As New RasterRenderer()
renderer.RegistrationName = “demo”
renderer.RegistrationKey = “demo”

‘ Load PDF document.
renderer.LoadDocumentFromFile(“multipage.pdf”)

For i As Integer = 0 To renderer.GetPageCount() – 1
‘ Render first page of the document to PNG image file.
renderer.RenderPageToFile(i, RasterOutputFormat.PNG, “image” & i & “.png”)
Next

‘ Open the first output file in default image viewer.
System.Diagnostics.Process.Start(“image0.png”)
End Sub
End Class
[/vb]
