Free zoom software for linux

FancyZoom is a fancy zoom. Actually it is not really that fancy.

I was surfing the net on my machine at home (equipped with a 14 inch monitor) and some of the icons were just too small to be interpreted into something recognizable by my strained eyes and thus FancyZoom was born.

Image Zoom is a Firefox extension which adds zoom functionality for images.
Easily zoom in, zoom out, fit image to screen or set custom zoom on individual images within a web page. All this can be done by using the context menu or a combination of mouse buttons and scroll wheel. Handy to see the finer details of smaller pics or to make very large pics fit within your screen

Cooka is a very simple image viewer written in C# (less than 900 lines of code, comments included) and compiled with Mono framework. The project is really essential: it has a file system browser in order to select the folder containing images to display; a thumbs viewer useful to see a preview of the images within the selected folder and some information like images name, size and dimension; and finally a "view" area used to display the selected image.

In order to handle images and to enhance image viewing, Cooka provides a simple toolbar that allows users perform some basic operation such as rotate, zoom, set as background.

But, why Cooka is an old style image viewer ? Simply because its possible to hide all the "interactive" areas (using keyboard shortcut) and focalize your attention on image. All the actions will be performed using your keyboard.

ShowImg is a feature-rich image viewer which can display numerous formats, including JPEG, PNG, GIF (animated), MNG, PSD, ... ShowImg application consists of a tree view frame, a directory and preview frame, and a view frame.
The (larger) view frame can be exchanged with the (smaller) directory/preview frame. It can preview and display images from multiple directories and search for identical images.
ShowImg also features a full-screen mode, zooming, sorting, dragndrop with Konqueror, support for images in compressed archives (tar, tar.gz, zip, ...) and kipi plugins.
Main features:
Viewer
- display JPEG, PNG (alpha layer supported), GIF, XCF, PSD, etc. files;
- open several directories, and archives (.tar.gz, .tar.bz2, .zip, ...);
- apply filters to displayed image;
- preview, fullscreen, slideshow, ``fit-to-screen, efficient zoom;
- open files with external programs;
- support EXIF header (JPEG file metadata);
- display a hexadecimal view.
Management
- batch rename;
- search for exact and similar images;
- several formats conversion;
- manage photo albums.
Configuration
- kipi plugins supported (see kipi plugin homepage);
- configurable interface.
Enhancements:
- Database added to manage images using KexiDB (http://kexi-project.org/),
- Video support added,
- SVG support added,
- RAR archive file support added.

UO Web Map project is a Web-based map with user-defined markers for Ultima Online.

UO Web Map is Web-based map over the different lands and dungeons in Ultima Online.

It is possible for the users to zoom and add their own points of interest directly on the map.

WebService::GoogleMaps is an automated interface to Google Maps.

SYNOPSIS

use WebService::GoogleMaps;

# Set up a new object with a viewport of 640 x 480 pixels
my $gmap = WebService::GoogleMaps->new( 640, 480 );

# Specify a location to view
$gmap->set(
latitude => 40.750275,
longitude => -73.993034,
zoom_level => 4, # valid values are 0..14, lower value is more zoomed
cache_dir => "/tmp", # optional, but recommended! Helps speed up future requests
pan_x => 0, # move viewport to the east (+) or west (-) a number of pixels
pan_y => 0, # move viewport to the south (+) or north (-) a number of pixels
);

# create a GD object containing our bitmapped map object
$gmap->generate_gd();

# or simply
# $gmap->generate_gd(40.750275, -73.993034, 4); # latitude, longitude, zoom_level

my $error = $gmap->error();
$error && print "Error: $errorn";

open (FH, ">", "mymap.png");
binmode FH;
print FH $gmap->{gd}->png;
close(FH);

WebService::GoogleMaps provides an automated interface to Google Maps http://maps.google.com/, which provides free street maps of locations in the USA and Canada. This module allows you to specify an image size, latitude, longitude, and zoom level and returns a GD object containing a street level map.

Seismic Toolkit 0.69a is designed to be a tool for processing and displaying seismic signal data in a graphical interface. Plot SAC ASCII and SAC_BIN data format, with zoom,unzoom, plot channel by channel, or plot all channel (until 2000, tested with 125).

Filtering the data: all filters are causal recursive IFR (Infinite Impulse Response) written using the bilinear Z-transform in the time domain. Their conception using a few number of coefficients gives them very fast with a low memory cost.

The adaptation factor of frequency warrants no deformation in the frequency domain of the transfer function. The main filters used are the following: Butterworth High-Pass and Low-Pass (n order), Farrer 10s-6s Low-Pass (a combination of rejector and Low-Pass specially designed for removing oceanic noise), Integrator, Derivator, Integrator with cut-off frequency, Derivator with cut-off frequency, Trend removing, Rejector (n-order), Envelop with Hilbert (not recursive at all), compensator of (n-order), Polynomial filter (n-order, not recursive at all ).

Major Functions:

1. Data plotting : channel by channel, all channels, zoom, unzoom, unfilter, instantaneous time and amplitude information with mouse pointer.
2. Fourier domain: Power Spectral Density (PSD) in linear-linear, log-log axes; independent windows for each channel, instantaneous frequency and amplitude information with mouse pointer, zoom, unzoom of spectra. Dirac, Hilbert transform, Time-Frequency representation (tested until 1 million of points per channel on 3 channels.
3. Polarization : easy and fast particule motion representation in both horizontal plane and incidence plane, with automatic computation of best direction with eigen vectors of the covariance matrix. Display of linearity and planearity coefficient.
   

Enhancements:

• New package (.deb) for Debian - Ubuntu
• New package (.dmg) for MAC OSX 10.4 (Tiger)
• Add function Derivator _Fc (a derivator with a cutting frequency
• Impose : setlocale(LC_ALL,"C") to avoid regional setting as decimal separator;
