Free zooming software for linux

Cornice is a cross-platform image viewer written in Python + wxPython + PIL. It doesnt pretend to be complete, fast, or even useful, but I like it and it is the viewer I use on both Linux and Windows. It has been inspired by the famous Windows-only ACDSee.
Why did I write it? Well, because I like ACDSee, but its not free and it doesnt run on Linux, which is my main platform. There already exists an ACDsee-like viewer, GTKSee, but it is unmaintained and it lacks some features I wanted (bookmarks, a good keyboard navigation and zooming).
First I tried to add such features to it, but then I decided to rewrite it from scratch, so that I could use it also on windows (and also because I had some troubles, especially when trying to port GTKSee to the gdk_pixbuf lib, and also because Python is more fun than C, and...
Main features:
- Fully cross-platform: it should run wherever wxPython does;
- Detail and thumbnail view for images;
- Image preview;
- Automatic recognition of images, with a variety of formats supported;
- Bookmarks;
- Full-screen view;
- Zooming and rotation;
- Slideshow;
- Good keyboard navigation (still not perfect, but this is true for all the features ;-);
- Image loading from zip archives;
- i18n support (with Italian and French translations available);
- EXIF data support;
- Some more...

newt - NEthack With Tiles.

Main features:

- sound support (via pmatch)
- joystick support
- many zoom modes to best view your game.
- realtime switching between tiled, ascii view

IV is a simple image viewer with pan and zoom viewing and many editing features.

Image Viewer (often refered to as IV) allows you to; view convert, grab (screenshot), print, rotate, crop, resize, display on desktop, add text, add comments, and open/edit/save animated images.

Additional viewing features include pan & zoom with just a click and a drag.

Currently, IV supports direct opening and saving with the image libraries:

libungif - Uncompressed GIF images
libjpeg - JPEG images
libpng - PNG & MNG images
libtga (internal) - TGA images
libXpm - XPM images

In addition, binary and text files can also be displayed with IVs internal File View and Hex View windows.

Dasher is a zooming predictive text entry system, designed for situations where keyboard input is impractical (for instance, accessibility or PDAs).

Dasher is usable with highly limited amounts of physical input while still allowing high rates of text entry.

Dasher is Free software released under the GPL. Further documentation may be found in the Doc/ subdirectory.

Zoom is a player for Z-Code stories or games. These are usually text adventures (interactive fiction), and were first created by Infocom with the Zork series of games.

Throughout the 80s, Infocom released many interactive fiction stories before their ambitions to enter the database market finally brought them low.

Zoom has versions for OS X and Unix-like operating systems using X-Windows. You can download the OS X version or the source code using the links to the left. Zoom can be redistributed under the terms of the GNU General Public License.

Obviously, Zoom is quite capable of playing Zork, so those of you who have access to the increasingly rare Infocom games can continue to play them. However, back in 1993, Graham Nelson released Curses and more importantly the Inform compiler that created it. There is now a considerable collection of new interactive fiction of variable quality available. Bafs guide to the interactive fiction archive is absolutely essential for those new to the scene.

SDL::Tool::Graphic is a module for zooming and rotating SDL::Surface objects.

METHODS

zoom ( surface, xzoom, yzoom, smooth )

rotoZoom ( surface, angle, zoom, smooth )

SDL::Tool::Graphic::rotoZoom rotates and fixed axis zooms a SDL::Surface.

grayScale ( surface )

SDL::Tool::Graphic::grayScale rotates and fixed axis zooms a SDL::Surface.

invertColor ( surface )

SDL::Tool::Graphic::invertColor inverts the color of a .

ps3 is a utility for monitoring process activity on a Linux machine. It is a little bit like top, except that:
- it displays all processes
- it updates itself up to 100 times per second instead of once every three seconds
- it shows a 3D chart, with interactive rotation, zooming and scaling
Installation:
Just type make.
