Extract Images from a PDF file – Solid Framework SDK

Extract images from PDF Files

The code below shows you how to extract all of the images from a PDF file and store copy them to a folder.

This sample requires a Tools license.

using System;
using SolidFramework.Converters;

namespace PDFExtractImages
{
    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
            // Call your Solid Documents License
            SolidFramework.License.Import(@"C:\MyFolder\license.xml");

            // Set the location of your the file you want to convert
            String pdfPath = @"C:\YourFolder\yourpdf.pdf";

            //*Extract Images from PDF File*//
            using (PdfToImageConverter converter = new PdfToImageConverter())
            {
                //Add the Selected File 
                converter.AddSourceFile(pdfPath);

                //Set where to save the images 
                converter.OutputDirectory = @"C:\MyPDFImages";

                //Extract the images using .Convert 
                converter.Convert();
            }
        }
    }
}
