Empty output file running extract example on a test pdf file

[bogct0mculhl]

Hi, I'm trying to understand how to use your library, but I'm not able to run your example code corrrectly:

git clone https://github.com/jrmuizel/pdf-extract.git

cd pdf-extract

wget https://orimi.com/pdf-test.pdf

cargo run --example extract pdf-test.pdf

The output file is empty...

cat pdf-test.txt

Using pdftotext the output file is filled with text:

pdftotext -layout pdf-test.pdf

cat pdf-test.txt

PDF Test File

Hi @bogct0mculhl! Do you want to use the code as a library or as a CLI executable? If you want to use it as a library, the easiest way to do so is probably this:

let bytes = std::fs::read("path/to/example.pdf").unwrap();
let out = pdf_extract::extract_text_from_mem(&bytes);
assert!(out.contains("Yukon Department of Education"));

That pdf is encrypted which is not currently supported. https://github.com/J-F-Liu/lopdf/issues/168

The extract example will now output a warning about it. https://github.com/jrmuizel/pdf-extract/commit/277fe7c5175eac65fda8dcabb960d1bd6e497505
