|This is poppler, a PDF rendering library.
|Poppler is a fork of the xpdf PDF viewer developed by Derek Noonburg
|of Glyph and Cog, LLC. The purpose of forking xpdf is twofold.
|First, we want to provide PDF rendering functionality as a shared
|library, to centralize the maintenance effort. Today a number of
|applications incorporate the xpdf code base, and whenever a security
|issue is discovered, all these applications exchange patches and put
|out new releases. In turn, all distributions must package and release
|new version of these xpdf based viewers. It's safe to say that
|there's a lot of duplicated effort with the current situation. Even if
|poppler in the short term introduces yet another xpdf derived code
|base to the world, we hope that over time these applications will
|adopt poppler. After all, we only need one application to use poppler
|to break even.
|Second, we would like to move libpoppler forward in a number of areas
|that don't fit within the goals of xpdf. By design, xpdf depends on
|very few libraries and runs a wide range of X based platforms. This
|is a strong feature and reasonable design goal. However, with poppler
|we would like to replace parts of xpdf that are now available as
|standard components of modern Unix desktop environments. One such
|example is fontconfig, which solves the problem of matching and
|locating fonts on the system, in a standardized and well understood
|way. Another example is cairo, which provides high quality 2D
|rendering. See the file TODO for a list of planned changes.
|Please note that xpdf, and thus poppler, is licensed under the GPL,
|not the LGPL. Consequently, any application using poppler must also
|be licensed under the GPL. If you want to incorporate Xpdf based PDF
|rendering in a closed source product, please contact Glyph & Cog
|(www.glyphandcog.com) for commercial licensing options.
