After writing down my latest ideas for better Piwik visualizations, I just couldn't wait to see them in action. Since the Open Flash Chart library doesn't support multi-level pie charts I decided to create the visualization from scratch. The initial version (0.1) took me about two hours coding. In the ...

If you're using Piwik, the open source web analytics tool, then you probably already missed a map visualization of your visitors location, which is a standard feature of all major web analytics tools. As I really like the idea of ...
There are a lot of nice text features in the new flash text layout framework but obviosly there is still one important feature missing: Hyphenation. Until today, there is no native hyphenation support in the flashplayer. I decided to fill this gap by porting the Hyphenator.js library by Mathias Nater to ActionScript. In this post I'll demonstrate text hyphenation in flash.
Today I want to introduce as3-proj, an actionscript port of the java map projection library by Jerry Huxtable, which is itself an partial port of the PROJ.4 library. It's basically a huge set of over sixty ...
Most people already know about the wonderful and free flag icon set from famfamfam. They are used in many websites and software projects around the world and beautified countless country selection boxes. Today I had to create such beautiful country ...
Update: I strongly recommend the use of as3-proj instead, which includes far more map projections and lots of other features. Something you definitely need if you're planning to create some geospatial visualizations from scratch is map projection. Map projection means the conversion of sphere coordinates (basically pairs of latitude and longitude values) to 2D-screen coordinates. While this is very easy for smaller regions like single countries things are getting complicated if you want to display the whole world.
I recently had the problem to store a flash animation into a video file. I first tried some tools I found in the net, but they all run into problems because my flash movie doesn't integrate the MovieClip timeline. Tools like swf2avi are stopping the conversion after the first ...
Polygons play a major role in a lot of visualization applications. Beside of the possibility of drawing polygons, there is neither an explicit presentation of polygon data nor are common polygon operations supported in ActionScript. As far as I know there is no simple solution available that solves the following geometrical problems for simple 2D polygons, so I wrote one.
Nachdem ich im letzten Eintrag meine JavaScript-Definition für LaTeX-Listings veröffentlicht habe, sollen nun auch die restlichen, in meiner Studienarbeit verwendeten Sprachen nicht fehlen. HTML5 \lstdefinelanguage{HTML5} {morekeywords={a, abbr, address, area, article, aside, audio, b, base, bb, bdo, blockquote, body, br, button, canvas, caption, cite, code, col, colgroup, command, datagrid, datalist, ...
Nur für den Fall, dass das noch jemand irgendwann mal braucht ;-) Mit der folgenden LaTeX-Anweisung kann man für per Listings eingebundene Quelltexte die Sprache JavaScript hinzufügen:
Here is a small actionscript3 class for converting colors between different color spaces like RGB, HSV, HSL and HSB. You can input and output the colors either as integer or string value or as serperated color components (e.g. hue, saturation and lightness). The class has no other dependencies. API /* * ...
PerceptualColor ist eine ActionScript3-Klasse, die zwischen den Farbräumen RGB, HSV, HSL und HSI umrechnen kann. RGB-Farben können dabei sowohl als Integer (zb. 0xFF0000), Hexadezimalzahl (z.B. "#FF0000") oder komponentenweise (R: 255, G:0, B:0) ein- und ausgegeben werden. Die Klasse hat keine weiteren Vorraussetzungen und läuft ab Flashplayer 9.
