gppdf's Introduction

GFXprim

GFXprim is Open-source modular 2D bitmap graphics library with emphasis on speed and correctness. It comes batteries included, but free from bloat.

It includes:

  • Graphical user interface widgets with object hierarchy and declarative layouts.
  • Clean and non-intrusive implementations of elementary data structures.
  • Multiple rendering backends supporting desktop to embedded.
  • Integrations with many image loaders.
  • Image filters
  • Sample applications including image and PDF viewers.
  • Many tests

See http://gfxprim.ucw.cz for details.

The problem is with several PDF files. Actually I haven't been able to open any PDF file. I used packaged versions of libgfxprim.so.1 and libmupdf.so.1, I also tested packaged version (https://build.opensuse.org/package/show/home:metan/gppdf).

Sefault in init
