Free screen ruler software for linux

screen-scraper project is a tool used to extract data from web sites. You might use screen-scraper for the following purposes:
- Data Mining and Extraction
- Data Migration
- Application Integration
- Business Intelligence
- Web Task Automation
- Portal Components
- Meta-Searching
- Archiving
The screen-scraper application consists of two primary pieces:
- Workbench: A graphical user interface provides an intuitive approach that allows you to designate pages and specific pieces of information to be extracted.
- Server: After using the workbench to designate the data to be scraped, screen-scraper can be run in a server mode, much like a database. External applications can then connect to screen-scraper, which will pull data off of the designated web sites, then return them to the calling application. For example, you might build a web-based application using Active Server Pages (ASP) or PHP that invokes screen-scraper to search for products found on an external web site in real-time.
Additionally, screen-scraper can be started in a non-graphical mode from the command line such that it can be scheduled or invoked on-demand.
screen-scraper can automate many of the tasks typically required when scraping data from web pages, such as tracking cookies, logging in to web sites, and traversing search results pages.
Depending on the programming languages and platforms you most prefer, screen-scraper is likely to be familiar to you. screen-scraper contains an internal scripting engine that supports:
- VBScript
- JScript
- Perl
- Interpreted Java
- JavaScript
- Python
When invoking screen-scraper externally take your pick from the following languages:
- Java
- PHP
- Anything COM-based (such as Active Server Pages, Visual Basic, and Visual C++)
- .NET (both Microsoft-based and Mono)
- Cold Fusion
Enhancements:
- Several bugfixes and minor features have been added, including automatic backup of the database, enhanced HTML rendering and HTML stripping, fixing an error that caused duplicate scripts to appear at times on import, and fixing multiple errors relating to international character sets and non-ASCII characters.

Screenie is a small and lightweight screen frontend that is designed to be a session handler that simplifies the process of administrating detached jobs by providing an interactive menu.

reset-screen is a very simple Qt 4 program that displays a simple cross hatch pattern on your monitor.

Why is this useful? Well, it makes the auto-sync feature of the flat panel LCD monitors out there both faster and more accurate (well, for mine anyways).

I have to run this every other time I start KDE so I figure others may find it useful as well.

This isnt really useful for laptop users I think, but you may need it. Who knows? :)

This is a very simple program, which a very simple build system.

OS X Login Screen is a very accurate OS X login Screen Mimic for Kubuntu Linux.

scrot is a command line screen capture utility.
scrot (SCReen shOT) is a simple commandline screen capture utility that uses imlib2 to grab and save images.
Multiple image formats are supported through imlib2s dynamic saver modules.
Enhancements:
- Patch from Claes Nasten
- Enhances thumbnail related options:
- First, specifying -t would break the $f param to -exec.
- Second, the thumbnail and the screenshot got different timestamps.
- Third, one werent able to specify geometry with -t.
- I fixed those and added, $m ( mini, instead of $t as it was taken ) so that one can do.
- About the geometry, having either the width or height set to 0 makes it fill in the other pertaining the aspect ratio.

Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. The project is intended for users with multiple computers on their desk since each system uses its own monitor(s).

Redirecting the mouse and keyboard is as simple as moving the mouse off the edge of your screen. Synergy also merges the clipboards of all the systems into one, allowing cut-and-paste between systems. Furthermore, it synchronizes screen savers so they all start and stop together and, if screen locking is enabled, only one screen requires a password to unlock them all.

With synergy, all the computers on your desktop form a single virtual screen. You use the mouse and keyboard of only one of the computers while you use all of the monitors on all of the computers. You tell synergy how many screens you have and their positions relative to one another. Synergy then detects when the mouse moves off the edge of a screen and jumps it instantly to the neighboring screen. The keyboard works normally on each screen; input goes to whichever screen has the cursor.

In this example, the user is moving the mouse from left to right. When the cursor reaches the right edge of the left screen it jumps instantly to the left edge of the right screen.

You can arrange screens side-by-side, above and below one another, or any combination. You can even have a screen jump to the opposite edge of itself. Synergy also understands multiple screens attached to the same computer.
Running a game and dont want synergy to jump screens? No problem. Just toggle Scroll Lock. Synergy keeps the cursor on the same screen when Scroll Lock is on. (This can be configured to another hot key.)

Do you wish you could cut and paste between computers? Now you can! Just copy text, HTML, or an image as you normally would on one screen then switch to another screen and paste it. Its as if all your computers shared a single clipboard (and separate primary selection for you X11 users). It even converts newlines to each computers native form so cut and paste between different operating systems works seamlessly. And it does it all in Unicode so any text can be copied.
Do you use a screen saver? With synergy all your screen savers act in concert. When one starts they all start. When one stops they all stop. And, if you require a password to unlock the screen, youll only have to enter a password on one screen.

If you regularly use multiple computers on one desk, give synergy a try. Youll wonder how you ever lived without it.
