Free viewer program software for linux

tc-viewer provides the ability to watch current transfers that take place in HTB and HFSC traffic shaping classes on specified interface.

tc-viewer reads output from: tc -s class show dev iface, and analyzes (for each class) values in lines like this one :

JExifViewer is a Java program for displaying and comparing Exif informations stored in JPEG files created by digital cameras. JExifViewer is an Open Source project released under the GPL.

JExifViewer has an image viewer in which you can rotate and/or flip, zoom in/out the selected image. You can also print an image.

You can also rename, copy, move and delete images.

At the moment JExifViewer is localized in English and German.

A short online help is available for JExifViewer.

Installation:

tar xzf linux_jexifviewer.tar.gz
cd jexifviewer
./jstart

RSS Viewer is a comfortable and portable viewer for RSS/RDF-compatible newsfeeds. It is written completely in Java and licensed under the GNU General Public License.
Rss Viewer is proven to run on Windows, Linux and MacOS X. Other Java enabled platforms should work as well.
Main features:
- multiple views for everyones taste
- built-in HTML article preview
- external browser support
- drag and drop
- article database

Pipe Viewer project is a terminal-based tool for monitoring the progress of data through a pipeline.

It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion.

pv is now considered to be stable code: it appears to work reliably on systems it has been tested on.

Mesh Viewer is an easy to use lightweight application to display triangular meshes from a variety of file formats (see 3D formats).
Mesh Viewer uses the OpenGL API to render the models. The program was born under the need for quickly displaying reconstructed triangulated meshes. The Mesh Viewer based on an idea and an early elementary implementation from Craig Robertson.
The current version was developed by Helmut Cantzler. Triangular meshes can be displayed texture mapped (optional with bilinear filtering), solid or as a skeleton (full or just the front lines).
The surface normals of the triangles can be displayed optionally. Features (from a different data file) like edges and points can be displayed into the mesh. Loaded models can be rotated, translated and scaled (all done with the mouse). The model is lighted by multiple light sources.
Viewpoints can be saved. Screenshots of the model can be taken (as BMP, JPEG, PNG and so on). The program is able to calculate the texture map for the 3D model (experimental!).
It can read:
- PMesh files (used at the Vision group of the University of Edinburgh)
- GTS files (from the Gnu Triangulation Library)
- Geomview files (only format "OFF")
- PLY files (only ASCII format)
- VRML 1 files (no texture mapping)
- VRML 2 files
- Feature file
- List file
File format descriptions:
The PMesh format begins optional with a header. The first header line consists of "#pmesh". The header ends with the first line not starting with a "#". The data starts with nv lines of the format "v float float float" for the vertices. Follows nf lines of the format "p 3 int int int" for the triangles. Each line contains the three indices of the vertices. The index of the vertices starts at one.
The GTS format is describe shortly. The first line contains three unsigned integers separated by spaces. The first integer is the number of vertices, nv, the second is the number of edges, ne and the third is the number of faces, nf. Follows nv lines containing the x, y and z coordinates of the vertices. Follows ne lines containing the two indices (starting from one) of the vertices of each edge. Follows nf lines containing the three ordered indices (also starting from one) of the edges of each face.
The Geomview formal starts with a header consisting of the format line "OFF" and a second line with three integer numbers. The first integer is the number of vertices, nv, the second is the number of polygons, np, and the third number is typically "0". Following are the nv lines of vertices (each consists of three floats). The other part of the file are np lines of polygons. The first number of each line stands for the size of the polygon. Mesh Viewer just reads polygons consisting of 2 or 3 vertices. Following are a number of indices of the vertices depending on the size of the polygon. The index of the vertices starts at zero.
VRML is only supported partly. The Mesh Viewer extracts only vertices and triangles from VRML files and ignores all other shapes. Shapes in VRML 2.0 are rotated, scaled and translated if necessary. The file name for JPEG texture and texture coordinates are read from VRML 2.0 files if existent.
The Feature file is used to store vertices and edges. A feature file can be loaded beside the mesh to display vertices or edges into the mesh. The first header line consists of "#list". The header ends with the first line not starting with a "#". The lines consists of either vertices or edges. A vertex line consists of the format "fv float float float". A edge line starts with "fe" followed by the x, y and z coordinates for the start and the end vertex.
The List file is only a text file listing n mesh files, which a loaded subsequently as different shapes into one mesh. Lists are useful for displaying a segmentation of a mesh. The first header line consists of "#list". The header ends with the first line not starting with a "#". The following n lines consists of the names for the mesh files (one per line).

Quick Image Viewer (qiv) is a very small and fast GDK/Imlib image viewer designed to replace the classic image viewers like xv or xloadimage. Quick Image Viewer program runs on FreeBSD, Linux (libc5/glibc), Solaris (SunOS) and HP-UX.
Main features:
- moving & zooming image in fullscreen mode.
- setting image as x11 background (centered,tiled,stretched..) with user settable background color
- fullscreen viewing with a great statusbar
- external "qiv-command" program support
- screensaver mode
- brightness/contrast/gamma correction
- real transparency
- maxpect (zoom to screen size while preserving aspect ratio)
- scale_down (scale down to big images to fit screen size)
- slideshow (with random order if you want)
- filename filer
- flip horizontal/vertical, rotate left/right
- delete function (move to .qiv-trash/)
- jump to image number x, jump forward/backward x images
Enhancements:
- This release has some bugfixes and new options.

frob 3D viewer project is a 3D object point/wireframe/polygon viewer - called frob3dv for lack of a better name.

I wrote this version mainly to learn c++. Also it was the first program I wrote after I got a PC (and put linux on it), but it has a long history. Many years ago I wrote a few stacks in Hypercard (on a Mac SE) for editing and displaying 3d shapes. I then ported it to modula-2 , using the free MacMETH compiler, then MOPS, a great free object-oriented programming language and application framework for the mac.

That is where it got most of its current class hierarchy. At that stage it was still only a wire-frame viewer. I then ported it to c++ for the macintosh using the Macintosh Programmers Workshop. When I wiped Windoze off my PC and put an operating system (linux) on it, I ported it to X and added the polygon drawing.

Process Viewer is a small utility similar to top which displays all the processes on a linux system. Its written using the FOX Toolkit.
