Hi,
I can't get the PDF page content and resources ues the itextsharp 4.0.3 when
the PDF type is distiller.
The pdf name is:1571es.pdf
Download address is:
http://www.fda.gov/downloads/AboutFDA/ReportsManualsForms/Forms/UCM083533.pdf
I have tracked the itextsharp source code found the contents Is Stream, the
code as below:"
if (contents.IsStream()) {
return GetStreamBytes((PRStream)contents, file);", I call this method only
return 78 bytes contents, not all of the page content and resources; but
another PDF the type is still distiller, the pdf name is:356HesCA2LOD8P.pdf,
download address is :
http://www.fda.gov/downloads/AboutFDA/ReportsManualsForms/Forms/UCM082348.pdf,
i found this PDF contents Is Array, the code as below:"
else if (contents.IsArray()) {
PdfArray array = (PdfArray)contents;
bout = new MemoryStream();
for (int k = 0; k < array.Size; ++k) {
PdfObject item = GetPdfObjectRelease(array[k]);
if (item == null || !item.IsStream())
continue;
byte[] b = GetStreamBytes((PRStream)item, file);
bout.Write(b, 0, b.Length);
if (k != array.Size - 1)
bout.WriteByte((byte)'\n');
}
return bout.ToArray();
}", I call this method can get all of the page content and resources.
So could you help me how to get the 1571es.pdf page content and resources,
i'm looking forward to your reply, thanks!
Thanks and Regards
