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.

WP Clipart now includes a viewer to expediate the use of the clipart collection. While it is true that any editor will allow you to "browse" your system for images to open or insert, the interface can often be slow, or you have to dig through the system to find the clipart, and often the display of the images (in thumbnail form) is very small.

The Clipart Viewer (CAV) is quick, has a nice size display (up to 240x240 pixels) and the images are displayed, when resized, in their original proportions. In other words, you get a real good look at the images before you pick one. CAV then lets you copy the image in original size to the clipboard to paste into your program. The preview quality and speed are the biggest advantages to using CAV, but there are a couple other advantages that are not immediately obvious.

First, you paste the saved image while keeping CAV open. This allows you to change your mind to try a different clip or copy and paste another image quickly. You dont have to block your editor with another "open" or "insert" dialog to keep going. You can also paste it into a graphics editor if you want to do a little tweaking and not have to find it again.

On Linux, you often cannot get images into the clipboard to use in apps like AbiWord or the Gimp. Simply by keeping CAV open, Abi and Gimp can be pasted into.

I programmed CAV with Python/wxPython/wxGTK. Dependencies should not be a problem on any system as I have created "stand-alone" executables for both Linux and Windows, using cxFreeze and py2exe, respectively, and included these in the downloads for WP Clipart. [They are in the "Viewer" folder.]

Below are a few screenshots. The use of the little app is fairly self-explanatory . . . by clicking on the "caviewer" in the wpclipart/viewer directory (or more easily, by making a symlink or shortcut to that file) CAV will open with its search tree open to the clipart directory.

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.

pcpViewer is a 3D viewer of data gathered through the excellent "Performance Co-Pilot" library.

You can see usage of CPU time, net devices, memory, hard drives, and virtually any data exported by the pcp library and daemon.

I first started this "pet project" as a 3D xosview replacement (thanks for inspiration), so one of the goal is to get the same level of responsiveness as xosview.

Ekspos is platform independent Java image viewer program. Ekspos Image Viewer support most popular image format: PNG, JPEG, and GIF, where additional image format can be added through Java ImageIO plugin.
It consists of 2 parts: shell browser and viewer. Shell browser allows you to navigate your image collection and youll be able to browse images in tree, detail, list, icon and thumbnail view. The viewer provide progressive view of images with zoom and pan capability.
Main features:
- Image Format (Default): JPEG, PNG, and GIF
- Support ImageIO plugin for additional Image Format
- Support 4 views: detail, list, icon, and thumbnail
- Thumbnail caching for fast preview
- Written entirely in Java

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).

Image Viewer is an image viewer with real-time interactive pan and zoom viewing that uses the GTK+ toolkit and Imlib (or Imlib2).

Main features:
- View
- Convert
- Grab (Screenshot)
- Print
- Rotate
- Crop
