Free table viewer software for linux

image-viewer is a very simple Kommander script. But written following one of the 2-3 tutorials you can find on the net. Included in tarball you can find this guide to introduce in Kommander GUI. The site is: http://applications.linux.com/article.pl?sid=04/12/17/2033227&tid=49 and was written in 2004 by Michał Kosmulski

I know people want to use this great program..but documentations are very poor...this example helps people who wants to learn something about simple array, combobox, label and connections between signals and slots..very very important.

So, i hope the guide and the example will be usefull.

ThinkFree Viewer allows you to view ThinkFree or Microsoft Office word processing, spreadsheet, and presentation files without having any other office applications installed. After installing the appropriate Widget simply drag and drop files from your desktop, or copy and paste the Web URL into the ThinkFree Widget.

ThinkFree Widgets allows users to open email attachments with ease, and supports the following file formats: .doc, .rtf, .txt, .xls, .csv, .ppt, and .pps.

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 :

Measured speeds may little vary from the real ones.

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).

QVV is image viewer based on TrollTechs Qt Toolkit! QVV is small, simple, handy ( last one is IMO ). However the sources are there -- you can come up with your own opinion.

NOTE: QVV 0.16 AND LATER VERSIONS REQUIRE QT 3.x!

QVV allows you to browse directories with lynx-like interface, view images browse next/prev image while showing image window or in the directory list, multiple image windows and directory browsers can be opened/closed with a single key, panning easy with arrow keys or mouse and few other things as well.

QVV is only few hundred lines of source code and handles as much file formats as Qt does -- JPEG (all sorts of jpegs that jpeglib supports), PNG, GIF, XPM and more..

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.

Gerber Viewer in short gerbv is a viewer for Gerber files. Gerber files are generated from PCB CAD system and sent to PCB manufacturers as basis for the manufacturing process. The standard supported by gerbv is RS-274X.

The basic difference between RS-274D (the old standard) and RS-274X is basically the addition of apertures in RS-274X. It might be possible to make an RS-274X file out of an RS-274D file and an aperture list.

gerbv also supports drill files. The format supported are known under names as NC-drill or Excellon. The format is a bit undefined and different EDA-vendors implement it different. But basically you need to have the tools definition in the file, then the parser is quite tolerant. The different holes are shown as dots in the (scaled) correct size.

The different layers of the PCB are separated into different files. gerbv can load all files at the same time and display them "on top of each other". You can independently turn them on and off.
