TileViewer
A jQuery plugin (TileViewer) and supporting script (make_tiles.sh).
make_tiles.sh
A bash script which uses ImageMagick to split a large image into a number of tiles at various zoom levels. These images are saved along with a setting.json file in the output directory. The tile size of 256 pixels was chose somewhat at random, though smaller sizes tend to cause a computational hit, while larger sizes take longer to load. For most photos jpg is the more compact output form. Python, /usr/bin/bc, and simple bash math is used in computations.
Please note that the output directory will be deleted by the script before it creates any images.
usage ./make_tiles.sh options
This script will convert the submitted file into a collection of tiles for use with the TileViewer jQuery plugin.
Options:
-h Shows this message
-i Source file name (required)
-o Output directory (required). This directory will be irrevocably removed if it already exists!
-t Output file type, "jpg" by default. May be anything ImageMagick supports as an image output file (jpg, png, gif)
-b Background color, "#444" by default.
-s Tile size in pixels, 256 by default
jquery.tileviewer.js
The jQuery Plugin. In general it simply requires a div with relative or absolute positioning and a set height and width. An example of how to use this plugin can be found in the index.html code. The imagedir is a required parameter. This should point to the directory which contains the output of the make_tiles.sh script. Do not include a trailing slash in the imagedir.
