Hi,

you can use BeforeDrawImage event:

Code:
var pdfPath = "myPDF.pdf";
const float dpi = 150;

using (var pdfReader = new PdfReader(pdfPath, dpi, dpi))
using (var content = pdfReader.Frames[0].GetContent())
using (var dumpContainer = new GraphicsContainer(pdfReader.Frames[0]))
using (var gr = dumpContainer.GetGraphics())
{
    int index = 0;

    gr.BeforeDrawImage += (sender, args) =>
    {
        args.Bitmap.Save($"Image_{index}.tif");
        index++;
        args.Cancel = true;
    };

    gr.DrawContainer(content, 0, 0);
}
Best regards,
Eugene Kosmin.
