Hi,
Here you are the sample code and the sample image-on-text pdf that generates
the exception.
string documentName = @"C:\Temp\pdf\22568 20.pdf";
string extractFolder = @"C:\Temp\extractedImages";
string imageName = extractFolder + Path.DirectorySeparatorChar +
Path.GetFileNameWithoutExtension(documentName) + "_{0:000}.{1}";
PdfReader reader = new PdfReader(documentName);
PdfReaderContentParser parser = new
PdfReaderContentParser(reader);
int i = 1;
try
{
string imgpath = String.Format(imageName, i, "{0}");
parser.ProcessContent(i, new
ImageRenderListener(imgpath));
}
catch (Exception ex)
{
MessageBox.Show("Cannot process content of " +
String.Format(imageName, i) + ex.Message);
}
the ImageRenderListener is a direct implementation of the IRenderListener
interface just to save the image content of the pdf file.
The stack trace is as follows:
