This site is a Regular Expression evaluator for three different regular expression systems: 1. PHP PCRE. 2. PHP Posix. 3. Javascript.

Most but not all Perl regular expression constructs are supported by the Java regex engine; see the Javadoc for java.util.regex.Pattern for full details. (See the section "Comparison to Perl 5")

*CIE Color Calculator: Converts among most of the CIE color models as well as providing correlated color temperature and standard RGB conversions. *Companding Calculator: Converts among luminance, CIE L*, density and gamma. Includes both a numeric calculator and a graphical display. *Color Difference Calculator: Computes color differences using several different methods (CIE1976, CIE1994, CIE2000, CMC). *Chromatic Adaptation Calculator: Converts colors between reference whites using different chromatic adaptation algorithms. *CIE Spectral Display: Calculates and displays many useful CIE functions, such as the Standard Observers, the Standard Illuminants and blackbody radiators. *Spectral Calculator Spreadsheets: Calculates colorimetry, densitometry and RGB values from your spectral data. *Levels Calculator: See how you lose levels when you pass data through curves. *ColorChecker Calculator: Performs many spectral calculations on the 24 colors of the ColorChecker chart. *ColorChecker RGB Summaries, Spreadsheets and Lab TIFF File: You will find three things on this page, a) summaries of the ColorChecker colors, expressed in each of many standard RGB color spaces, b) spreadsheets that allow you to find which RGB color space is closest to your RGB values, and c) a computer generated Lab TIFF file of the ColorChecker. *Munsell Display Calculator: Displays the Munsell color set (2734 colors) in xyY, Lab and Luv. This is a useful tool for evaluating uniform perceptual color spaces. Also included is an explanation of the infamous "blue turns purple" problem often seen with printer profiles. *Dot Gain Calculator: Performs the standard Murray-Davies dot gain equation to your density measurements. *Dot Gain from Lab or Profile: Two spreadsheets which calculate dot gain from Lab measurements, also allowing you to measure the dot gain of a CMYK ICC printer profile.

LocaPoint is the state-of-the-art location pointer code that can express any location of the world, only with 12 letters. SW8.HQ9.CS6.PQ8 Statue of Liberty SD9.XC4.FE1.CV4 Tokyo Tower UL4.MZ7.FP3.TU4 London Eye You can say prompt answer, "10:35" or "16:45" to the question, "What time is it". But, can you say a prompt answer to the question, "Where is it" ? You may use Address, Landmark, Direction, or Map. But there is no prompt way to answer - before LocaPoint came. Application LocaPoint can be used in anything that need to show a location. * Directory/Travel Guide/Restaurant Guide * Blog/Travel Diary * Real Estate information * Pleasure * Appointment * Advertising/Signs * and More.... Advantages of using LocaPoint LocaPoint has a unique format - "Letter, Letter, Number" , that leads a three advantages. First, you can easily recognize that this is a information regarding a location by this format, as you do for "***@***.com" as email address, or "http://****" as URLs. Second, the pattern of "Letter, Letter, Number" helps you to cognize, read, tell, listen, input, or remember. If a code has no pattern, or is totally random, you may have a difficult time to use it. Third, LocaPoint unique format is also "Detectable" for a computer. Computer can detect LocaPoint as a "location information" and can automatically start a GIS application, such as Map or Navigator. Here is a simple program to do it. By clicking this, every LocaPoint that is written in plain text will be "Linkify" to GoogleMaps with specified location.
