This is poppler, a PDF rendering library.Poppler is a fork of the xpdf PDF viewer developed by Derek Noonburgof Glyph and Cog, LLC. The purpose of forking xpdf is twofold.First, we want to provide PDF rendering functionality as a sharedlibrary, to centralize the maintenence effort. Today a number ofapplications incorporate the xpdf code base, and whenever a securityissue is discovered, all these applications exchange patches and putout new releases. In turn, all distributions must package and releasenew version of these xpdf based viewers. It's safe to say thatthere's a lot of duplicated effort with the current situaion. Even ifpoppler in the short term introduces yet another xpdf derived codebase to the world, we hope that over time these applications willadopt poppler. After all, we only need one application to use popplerto break even.Second, we would like to move libpoppler forward in a number of areasthat doesn't fit within the goals of xpdf. By design, xpdf depends onvery few libraries and runs a wide range of X based platforms. Thisis a strong feature and reasonable design goal. However, with popplerwe would like to replace parts of xpdf that are now available asstandard components of modern Unix desktop environments. One suchexample is fontconfig, which solves the problem of matching andlocating fonts on the system, in a standardized and well understoodway. Another example is cairo, which provides high quality 2Drendering. 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 alsobe licensed under the GPL. If you want to incorporate Xpdf based PDFrendering in a closed source product, please contact Glyph & Cog(www.glyphandcog.com) for commercial licensing options.
