^] an be used to extract images from PDFs:
static void ExtractAllImages()
{
string path = "";
using (PdfDocument pdf = new PdfDocument(path))
{
for (int i = 0; i < pdf.Images.Count; i++)
{
string imageName = string.Format("image{0}", i);
string imagePath = pdf.Images[i].Save(imageName);
}
}
}
This seems to be a good start point, good luck!
