Hi there,
I'm trying to retrieve images in a pdf document created with Ghostscript
virtual printer.
In it, I'm able to retrieve in iText some streams, which I guess correspond
to the 4 images I see in Acrobat Reader when I open my pdf document.
Such streams have the entry /Flatedecode in the stream dictionary, but don't
have /Width, /Height, and other metadata for images.
I decode these streams with the following code
and then try to get image data with PdfImageObject, but get an exception
(since there are no other metadata in the stream dictionary)
PdfStream stream = (PdfStream) pdfobj;
if (stream.get(PdfName.FILTER) != null
&&
stream.get(PdfName.FILTER).equals(PdfName.FLATEDECODE)) {
byte[] decodedBytes = PdfReader.FlateDecode(
PdfReader.getStreamBytesRaw((PRStream)
stream), true);
}
PdfImageObject pio = new PdfImageObject((PRStream)stream);
Can somebody give me an advice?
Thank you
