Introduction ============ Glview is an image viewer using OpenGL to allow seamless panning and zooming over a lot if pictures. Textures are rescaled on the fly when zooming in and out. Glview is known to compile and run on GNU/Linux and Mac OS X. Compilation =========== Glview requires at least the following libs and their header files: - OpengL - SDL - Glut - Imlib2 Glview uses the optional 'extract' tool to gather info about images. Make sure all above dependencies are met, and compile by running 'make' Installation ============ Copy the resulting binary somewhere into your path or run from the local directory as ./glview Usage ===== usage: glview [options]
available options: -f Start fullscreen -h Show help -p N Use N parallel loader processes (2) -r Recursively find all images from the given path -V Show version For example, to browse all images found in the directory ~/pics and all of its subdirectories, run glview -r ~/pics Mouse controls: - left mouse click: zoom in to clicked image - right mouse click: zoom out to show all images - left mouse drag: pan - right mouse drag: zoom in/out - mouse wheel: prev/next image Keyboard controls: - + / -: zoom in / zoom out - p: previous image - n: next image - arrow keys: move around 1 image - f: toggle fullscreen - i: show info about selected image - l: switch layout between grid / hilbert mapping Notes ===== * Glview makes good use of multiple CPU's by forking multiple child processes to do the image decodeing. By default two loader processes are started, this number can be configured with the '-p' flag. * Glview caches quite heavily to disk, temporary files are stored into the directory .glview in the users home directory. * Performance depends greatly on the video hardware available. The developer has good results browsing up to 4000 imgages using a Nvidia Quadro NVS 140M on a Intel Core2 Duo notebook. Todo / whishlist ================ * Use texture compression to reduce cache size and video memory usage * Add PDF/Postscript reader backend Copyright ========= Copyright (c) 2008 Ico Doornekamp This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

2009-01-18 new - Implemented cache cleanup fix - cache also depends on file inode, mtime and size
