FPDF error: Unable to find "startxref" keyword

Question

I have an app that renders PDFs with FPDF.

It was working fine and for some reasons I had to change the PDF files and now I get this error:

Unable to find "startxref" keyword

If I restore the original files, the same error happens.

How do I fix this error?

Answer 1

You simply have to pass a local path instead of an URI to setSourceFile().

Answer 2

The problems lies (sometimes) in the pdf compression.

If you are using linux you can use this to uncompress the pdf:

 podofouncompress compressed.pdf decompressed.pdf
