1. In order to close issue #59, I've introduced user-configurable values for panning steps - for X- & Y-axis, separately. Now panning is called by pressing fiveway without mod_keys. When one presses Shift+FW, he/she changes panning steps in the following way - Shift-Left/Right = decrease / increase X-panning step (divide or multiply on factor 2), Shift-Up/Down = increase / decrease Y-panning step. The lowest value for panning steps is set 1. Both parameters, shift_x & shift_y, are saved to local settings (i.e. history file). 2. Manual zoom step was also made user-configurable. So, instead of two old zooming functions (with fixed 10% and 20%-steps), I made one function to zoom (Shift+<>), while the other (Alt+<>) changes the zoom step downto minimum 1%. 3. Fresh introduced function to change parameter rcountmax was added by storing rcountmax to both setting files - global settings & local ones (i.e. history file) - so that the rcountmax-priority (from low to high) is the following: default rcountmax=5 < its value in global settings < rcountmax stored for each concrete document. 3. Dirty, the extention-based hack to avoid reading not crengine-related parameters stored in history files. TODO: one has to finally introduce loadSpecialSettings() & readSpecialSettings() for PDFReader & DJVUReader and to store therein the reader-specific parameters (like globalgamma, bbox, globalzoom, globalzoom_mode; render_mode = for djvu-files only, etc.) 4. Some lua-code cosmetics (to make code more readable); for example: "self.pan_margin = settings:readSetting("pan_margin") or self.pan_margin" instead of "local pan_margin = settings:readSetting("pan_margin") if pan_margin then self.pan_margin = pan_margin end" 5. Fix for the today's tigran123 fix: issue #246 (details are included). Added InfoMessage:show() to inform most impatient users that the reader tries to redraw new zoo mode. 6. The fontface for the reading info (called by 'Menu') is restored to be in accordance with original intentions and with the same fontface in crereader.lua - namely, Font:getFace("rifont", 20) 7. Moved the exit hotkeys (Alt+Back & Home) to the end of hotkey list.
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
