Hi.
I suposed that an Image could be red and extract text from it. And If I want to
obtain text from the images, waht is the appropiated form or its impossible?
Thank you

Asunto: Re: [iText-questions] ITextSharp doesn´t read this pdf
Hi David,
Are you actually expecting this snippet of code to do OCR?
I've not inspected in detail the PDF you attached, but I think it only consists
of images (resulting from the scanning), and no text at all.
Could it be that you are making some wrong assumptions about what the text
extraction in iText does?
Cheers,
alexis

Asunto: ITextSharp doesn´t read this pdf
Hi,
I have one problem with this pdf I have attached. With other pdf files I
execute this code and it works ok. It gives me the text of the page:
PdfReader inputDocument = new PdfReader(fileName);
StringBuilder text = new StringBuilder();
for (int page = 1; page <= inputDocument.NumberOfPages; page++)
{
ITextExtractionStrategy strategy = new
SimpleTextExtractionStrategy();
string currentText =
PdfTextExtractor.GetTextFromPage(inputDocument, page, strategy);
currentText =
Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8,
Encoding.Default.GetBytes(currentText)));
text.Append(currentText);
}
inputDocument.Close();
MessageBox.Show(text.ToString());
But with the pdf attached it doesn´t work. The pdf attached is from a scannner
and generated with ghostscript and other examples are generated from Word.
Could anybody help me, please?
Thank you. Regards
