Games::Lineofsight is a Perl module.

Many games (Ultima, Nethack) use two-dimensional maps that consists of the squares of the same size in a grid. Line-of-sight means that some of the squares may represent the items that block the vision of the player from seeing squares behind them. With this module you can add that behaviour to your games.

SYNOPSIS

use Games::Lineofsight qw(lineofsight);

# The map has to be a two-dimensional array. Each member (or "cell") of the array represents one
# square in the map. In this example each cell contains only one character but you can put strings
# to the cells also - practical with the graphical games.

my @map=(
[split //,"..:..::........."], # this is the map
[split //,".......:..X....:"], # . and : represents the ground
[split //,"...X.....:...:.."], # X is the barrier for the sight
[split //,".:...:....:....."],
[split //,"..X....:..X....."],
[split //,"..X..:........:."],
);

my($width)=scalar(@{@map[0]}); # the width of the map
my($height)=scalar(@map); # the height of the map
my($barrier_str)="X"; # string that represents the barrier
my($hidden_str)="*"; # string that represents a cell behind a barrier
my($man_str)="@"; # string that represents the viewer
my($man_x,$man_y)=(7,3); # view point coordinates - the player is here

# recreate the map with line-of-sight

@map=lineofsight(@map,$man_x,$man_y,$barrier_str,$hidden_str);

# draw the map

for(my $i=0;$i < $height;$i++){
for(my $j=0;$j < $width;$j++){
print $man_x == $j && $man_y == $i ? $man_str : $map[$i][$j];
}
print "n";
}
or
# The lineofsight() calls get_barriers() and analyze_map() each time its called. If the viewer
# moves around the map a lot, its much faster to read in the barriers once and call only
# analyze_map() each time before drawing it.

use Games::Lineofsight qw(get_barriers analyze_map);

# The map has to be a two-dimensional array. Each member (or "cell") of the array represents one
# square in the map. In this example each cell contains only one character but you can put strings
# to the cells also - practical with the graphical games.

my @map=(
[split //,"..:..::........."], # this is the map
[split //,".......:..X....:"], # . and : represents the ground
[split //,"...X.....:...:.."], # X is the barrier for the sight
[split //,".:...:....:....."],
[split //,"..X....:..X....."],
[split //,"..X..:........:."],
);

my($width)=scalar(@{@map[0]}); # the width of the map
my($height)=scalar(@map); # the height of the map
my($barrier_str)="X"; # string that represents the barrier
my($hidden_str)="*"; # string that represents a cell behind a barrier
my($man_str)="@"; # string that represents the viewer
my($man_x,$man_y)=(7,3); # view point coordinates - the player is here

# get_barriers() returns a hash with the information about barriers in the map. In this example we
# declare the "X"-character as a barrier. As well you can declare it to be a string in the graphical
# games; for example "barrier.jpg".

my %barrier=get_barriers($width,$height,@map,$barrier_str);

# analyze_map() returns an array containing the original map looked from the view point. The cells
# behind the barriers are replaced with given strings. The barriers should be told to the subroutine
# calling first get_barriers()-subroutine as we already did.

my @map2=analyze_map($width,$height,@map,%barrier,$man_x,$man_y,$hidden_str);

#draw the map with the lineofsight

print "nOriginal map:n";

draw($width,$height,$man_x,$man_y,@map2,$man_str);

# move the viewer two squares right

$man_x+=2;

# refresh the map

my @map2=analyze_map($width,$height,@map,%barrier,$man_x,$man_y,$hidden_str);

#draw the map again

print "nViewer has moved:n";

draw($width,$height,$man_x,$man_y,@map2,$man_str);

sub draw{
my($width,$height,$man_x,$man_y,$map,$man_str)=@_;
for(my $i=0;$i < $height;$i++){
for(my $j=0;$j < $width;$j++){
print $man_x == $j && $man_y == $i ? $man_str : $$map[$i][$j];
}
print "n";
}

Free Reign project consists of a fully-3D city simulator.
Free Reign is a fully-3D city simulator, with advanced features planned such as ore mining, advanced financial models, and other features users request.
Main features:
- Crashes on demand
- OpenGL based graphics
- Fully 3D (rotateable map etc)
Installation
At the current time, installation of the game is by simply compiling and running the game in the compile directory. Compilation is standard:
Type ./configure in the FreeReign directory
Type make when configure succeeds.
Change to the src directory
Type ./fr to run the game
Enhancements:
- Bug fix in getMinHeight/Max - ugh. How did I ever forget that? My last C++ compiler must have assumed I was returning height..my God.

Menu Editor project is an editor for window managers start menus.
Compile
./configure
make all
Installation
If the compile was successful, then you can install with
su
(enter password)
make install
Enhancements:
- A bug that caused random miscalculations in the File selectors height, a failure to scroll buf when pasting items, and a scroll-to bug when selecting items were fixed.

Main features:
- Hardware rendering for fast image display
- Image precaching for even faster image display
- Intuitive click-and-drag navigation interface
- Hardware rotation and zooming via bilinear interpolation
- Zoom to arbitrary amounts, by steps of 10%, or fit to window width, height, or size
- Cool name

Zen-slideshow is a slideshow application for Web sites. The Web developer decides where zen-slideshow will be installed, the folder which will contain the images for the slideshow, the maximum width and height for the images in the slide show, whether or not to use thumbnails, the maximum width and height of the thumbnails, whether to use manual slideshow navigatioin controls, whether to use automatic slideshow controls, and many other options.

sidux-highway is a KDM theme as a modification of the Sabayon KDM theme "Open Future".

The highway picture was taken and modified by me, the go.png is taken from "crystalline black" icons (kde-look.org #46349), session.png and system.png are modified nuoveXT icons (kde-look.org #26449). The small pictures inside the monitor and folder are sidux wallpapers.

Modifications:

changed wallpaper and icons and resized and repositioned the userlist slightly, added missing screenshot

The highway picture is widescreen 1920x1200. Should be easy to resize it if needed. For your convenience I also have added a 1024x768 version, just rename it if you want to use it instead of the WUXGA picture.

To use the theme untar it to /usr/share/apps/kdm/themes/ and either change your /etc/kde3/kdm/kdmrc manually or use kcontrol if you have the kdmtheme module.

ATTENTION: If you use a display height other than 1200 the position of the login area (that half transparent stripe) will be different from what you see in the preview. If you want to have the same position with another display height you can easily adjust it by editing the file highway.xml with your favorite text editor. Just go to line 49 and change the y-value that by default is "-485". Its an easy rule of three: lets say you have a display height of 800: 800x485/1200=323 - go and replace -485 by -323.

BTW: If you just want the wallpaper: http://www.kde-look.org/content/show.php?content=52780

ImageInfo is a free Java class to retrieve properties from image files.

The following file formats are currently supported: JPEG, PNG, GIF, BMP, PCX, IFF, RAS, PBM, PGM, PPM and PSD (read why TIFF is not included). ImageInfo can recognize these formats, and in addition determine image width, height and color depth (bits per pixel).

Also check out ffident, my file format (group) and MIME type identification library. It extracts less information than ImageInfo (it only recognizes the format, no metadata), but it supports more formats and new formats can be added by editing a text file. Similar to file(1) / magic(5).

Using ImageInfo from within a Java application or applet

The image file can be any InputStream object or an instance of a class implementing DataInput (like RandomAccessFile). Here is some sample code on how to use the class:

ImageInfo ii = new ImageInfo();
// in can be InputStream or RandomAccessFile (or DataInput)
ii.setInput(in);
/* if you want to know how many images there are in a file,
uncomment the following line; will slow down ImageInfo
with animated GIFs */
//ii.setDetermineImageNumber(true);

// check does the actual work, you wont get results before
// you have called it
if (!ii.check())
{
System.err.println("Not a supported image file format.");
}
else
{
System.out.println(
ii.getFormatName() + ", " +
ii.getMimeType() + ", " +
ii.getWidth() + " x " + ii.getHeight() + " pixels, " +
ii.getBitsPerPixel() + " bits per pixel, " +
ii.getNumberOfImages() + " image(s).");
// there are other properties, check out the API documentation
}

Using ImageInfo as a command line program

ImageInfo also has a main method that makes it a command line tool. Assuming that ImageInfo.class is in your classpath, giving the class to java with some file names as arguments will be sufficient. Here is an example call including output:

$ java ImageInfo test.jpg
test.jpg
File format: JPEG
MIME type: image/jpeg
Width (pixels): 1556
Height (pixels): 2048
Bits per pixel: 24
Progressive: false
Number of images: 1
Physical width (dpi): 300
Physical height (dpi): 300
Physical width (inches): 5.1866665
Physical height (inches): 6.826667
