26.feb.17 :: Fixed a bug in the web code that was incorrectly dealing with white pixels.
26.jan.17 :: Added Perl code and Windows compiled binary to download section.
30.nov.15 :: Added JSONP output. The JSONP output is the same as JSON except that the output is wrapped in
22.nov.15 :: Added JSON output.
16.nov.15 :: Color clustering output has been improved. Pixels assigned to each color cluster are now shown in separate images.
15.nov.15 :: Lab coordinates are now reported as integers with `L \in [0,100]`, `a \in [-127,127]` and `b \in [-127,127]`. LCH coordinates are LCHab—the cylindrical representation of Lab.
12.nov.15 :: Added graphical RGB, HSV, LCH and Lab histograms to HTML output using the excellent c3.js d3-based plotting library. After futzing with dimple for several hours, I still could not make a histogram of two continuous variables using out-of-the-box functions. I was up and running using c3.js in 5 minutes.
9.nov.15 :: (v0.70) Output format and API have changed. Added image color clusters (k-means clustering), more color spaces (XYZ,Lab,CMYK), references to representative named colors. Fixed calculation for average value for hue in HSV and LCH space—now using angle-based mean of a periodic quantity.
4.mar.15 :: Average L, C and H values now shown. Standard deviation added to statistics.
3.feb.14 :: Histograms and raw pixel data is no longer being displayed by default. To show these report components, add
rawpixel=1 to the API URL.
8.nov.11 :: Added plain-text output to API. Use
text=1. Massaged style sheets for cleaner look-and-feel. Added raw pixel values to API output, which now includes LCH values.
3.nov.11 :: Added RGB and HSV histogram values to the XML output. Thanks to David Roberts from Durrell Institute of Conservation and Ecology at the University of Kent for this suggestion.
30.jul.07 :: Minor tweaks.
12.feb.06 :: Trying to work on the FAQ but my other current project, High Dynamic Time Range images is taking up my time.
9.feb.06 :: TODO: rework the FAQ
8.feb.06 :: Reworked the back end and cleaned up the interactive report formatting. Added histograms. Added precision option. Added human readable colour descriptor to HSV statistics.
