How to convert PDF files to images

Question

I need to convert PDF files to images. If the PDF file is multi-page，I just need one image that contains all of the PDF pages.

Is there an open sou

Answer 1

The NuGet package Pdf2Png is available for free and is only protected by the MIT License, which is very open.

I've tested around a bit and this is the code to get it to convert a PDF file to an image (tt does save the image in the debug folder).

using cs_pdf_to_image;
using PdfToImage;

private void BtnConvert_Click(object sender, EventArgs e)
{
    if(openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        try
        {
            string PdfFile = openFileDialog1.FileName;
            string PngFile = "Convert.png";
            List Conversion = cs_pdf_to_image.Pdf2Image.Convert(PdfFile, PngFile);
            Bitmap Output = new Bitmap(PngFile);
            PbConversion.Image = Output;
        }
        catch(Exception E)
        {
            MessageBox.Show(E.Message);
        }
    }
}
