idea is simple: when starting long operation (page renedering) invert box on top of screen which has relative width of this page. This allows easy overview where in document user is, along with indication that something is still happending. Perfect use-case are glossy magazines pdfs which have first two pages in hi-res graphics, so this indicator is very useful to see that something is still happending and that reader didn't die
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 libDjvuLibre sources into subfolder "djvulibre" - install CREngine sources into subfolder "kpvcrlib/crengine" - install LuaJit sources into subfolder "luajit-2.0" => note that there's a make target to do all the above. 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 And run the emulator like this: ./reader.lua /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
