KindlePDFViewer =============== This is a PDF viewer application, created for usage on the Kindle e-ink reader. It is currently restricted to 4bpp inverse grayscale displays. It's using the muPDF library (see http://mupdf.com/) and its UI is scripted using Lua (see http://www.lua.org/). The application is licensed under the GPLv3 (see COPYING file). Building ======== Follow these steps: - install muPDF sources into subfolder "mupdf" - install muPDF third-party sources (see muPDF homepage) into a new subfolder "mupdf/thirdparty" - install Lua sources into subfolder "lua" => note that there's a make target to do this. You need wget, unzip and git installed. Then just run "make fetchthirdparty". - adapt Makefile to your needs - run "make thirdparty". This will build MuPDF (plus the libraries it depends on) and Lua. - run "make". This will build the kpdfview application Running ======= The user interface (or what's there yet) is scripted in Lua. See "reader.lua". It uses the Linux feature to run scripts by using a corresponding line at its start. So you might just call that script. Note that the script and the kpdfview binary currently must be in the same directory. You would then just call reader.lua, giving the document file path as its first argument. Run reader.lua without arguments to see usage notes. The reader.lua script can also show a file chooser: it will do this when you call it with a directory (instead of a file) as first argument. Device emulation ================ The code also features a device emulation. You need SDL headers and library for this. It allows to develop on a standard PC and saves precious development time. It might also compose the most unfriendly desktop PDF reader, depending on your view. To build in "emulation mode", you need to run make like this: make clean cleanthirdparty EMULATE_READER=1 make thirdparty kpdfview The reader.lua script needs a device argument in order to cope with some slight differences between actual readers and the emulation. Run it like this: ./reader.lua -d emu /PATH/TO/PDF.pdf By default emulation will provide DXG resolution of 824*1200. It can be specified at compile time, this is example for Kindle 3: EMULATE_READER_W=600 EMULATE_READER_H=800 EMULATE_READER=1 make kpdfview
