During development testing, I’d prefer to create uncompressed, non-binary PDF files with iTextSharp so that I can check their internals easily. Like Theodore said you can extract text from a pdf and like Chris pointed out. as long as it is actually text (not outlines or bitmaps). Best thing to do is buy Bruno. just hadnt had time to investigate the possibility but we routinely grab a federal document from a website but we only care about including the.

Compress/Uncompress a pdf file

Please type your message and try again. Hi I am trying to get the cross-reference stream for weeks now, and itedt almost pulled all my hair out.

Uncoompress use the FlateDecode from iText first, then i applied the filter algorithm. But the results in hex i got are weird: But the results does not seem correct. I am expecting that the 1st column should be either 0,1 or 2 according to pdf specification.

Can anyone please help??? This content has been marked as final. Thanks for the reply.

I have tried the decodePredictor in iText passing the output stream from FlateDecode into decodePredictor. But the eventual output stream is a stream of 0 bytes.

I’ve been fiddling with iText for quite some time before deciding to un-filter the stream myself. I’m pretty sure the output from FlateDecode is correct because it could decode streams without decodeParms.

Again, I am not understanding. So I am confused why you are having problems with it.

How to create an uncompressed PDF file? | iText Developers

Have you posted to their support list? Yes, I’ve posted on their forum. But there’s no reply. However, I’m unsure on how to retrieve the inputs to getstreambytes from the pdf.

This is why I tried to use flateDecode and decodePredictor directly. It is probably due to my lack of understanding with using iTExt, and also I’m a novice in java.

So I thought that implementing my own decodePredictor in c might have been a better choice. But I need to get kncompress algorithm right first. Taking this as an example: If so, in the 3rd row, 0x8A becomes 0x8C? Again, thank you for your time. Go to original post.
