Original date:2018-02-21 11:48:58 Edited by: ghaberek Subject: wrapper for pdfium
hi, my second wrapper. it is for pdfium?- you can get the dll (32/64) easy, if you make an vs c project and import them with nuget. i use that for creating and reading pdf's. the libs are also available for linux etc. as far as i know.
i left the ugly comments in there, so that one has kind of a reference. my be some can use that.
