This is a document viewer application, created for usage on the Kindle e-ink reader. It is currently restricted to 4bpp inverse grayscale displays. For PDF files it is using the muPDF library (see http://mupdf.com/), for DjVu files djvulibre library and for ebooks (fb2, mobi, ePub, etc) crengine. It can also read JPEG images using libjpeg library. The user interface is scripted using Lua (see http://www.lua.org/).
The application is licensed under the GPLv3 (see COPYING file).
Follow these steps:
fetch thirdparty sources
manually fetch all the thirdparty sources:
- install muPDF sources into subfolder "mupdf"
- install muPDF third-party sources (see muPDF homepage) into a new subfolder "mupdf/thirdparty"
- install libDjvuLibre sources into subfolder "djvulibre"
- install CREngine sources into subfolder "kpvcrlib/crengine"
- install LuaJit sources into subfolder "luajit-2.0"
- install popen_noshell sources into subfolder "popen-noshell"
automatically fetch thirdparty sources with Makefile:
- make sure you have patch, wget, unzip, git and svn installed
adapt Makefile to your needs
make thirdparty. This will build MuPDF (plus the libraries it depends on), libDjvuLibre, CREngine and Lua.
make. This will build the kpdfview application
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, or any directory 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.
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.
If you are using Fedora Core Linux, do
yum install SDL SDL-devel.
If you are using Ubuntu, install
To build in "emulation mode", you need to run make like this: make clean cleanthirdparty EMULATE_READER=1 make thirdparty kpdfview
And run the emulator like this:
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
