Code-signing AIR applications and migration

Adobe granted me a free code signing certificate (for 1 year): Things are a little less “red” now. The first mail stated i should go to Thawte (which i had used for webserver certs multiple times) and apply for a cert. Ok, setup an account, added all info, submitted on 21st of february.  On 23rd [...]


flex: Making a percentage-sized VBox scroll

If you’re using a VBox with a pixel height, it will scroll as expected. If you’re using a percentage sized VBox, it won’t scroll when it’s content grows in size: the scrollbars will be “pushed somewhere up the component hierarchy”. To make it scroll, set it’s minHeight=0. Found this here.


RSS 1.0 + 2.0, Atom 1.0 on Yahoo – Virtual Earth – Google – OpenStreetMap …

To test the recent changes to my maptech library and to feature the omnipresent Geo-RSS feeds, i put together a simple yet powerful (at least i hope so) GeoRSS viewer. Features renders Atom 1.0, RSS 1.0 and RSS 2.0 supports W3C, Simple and GML feeds implements RSS 2.0′s TTL BTW, please add all georss-feed-urls you [...]


Zoomify, Virtual Earth, Yahoo Maps, Google Maps, OpenStreetMap and Bluemarble all in one AS3 flex library

After some thinking on how to integrate the code for linearly-projected maps (zoomify …) and mercator-projected maps (almost all others) into a single AS3 model, i found a very good, easy and straight-forward architecture. The trick was to separate the coordinate conversion into two steps: linearisation and linear interpolation [...]


Creating Real “Multi”-Layer Maps

Doing another viewer for a 200+ maps project, i discovered that combining overview and detail maps in the same view, rendered the system unusable with only a few layers. Naturally i did some optimizations on the layer drawing code. This resulted in a dramatical performance improvement when combining large overview maps with detail maps in [...]
