Flex: SPARQL Browser – Flex based dbPedia Semantic Web Explorer

SPARQL Explorer is an application which is a front end for the dbPedia SPARQL endpoint. For the best explanation of what dbPedia is you should go to their website. I quote: “DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to […]

Flex: flexTraffic – CCTV Images

I notice that Transport For London have upgraded their CCTV traffic ‘Jam Cam’ camera resolution. The quality of the images provided now is amazing. Spy on your friends and family. Image here flexTraffic is here. There is a bug under IE where the zoomin/zoomout icons on the camera popup are not aligned correctly. Bear with […]

Flex: IFrame Resizing

In place of a demo I thought I would try and have another stab at describing how to resize the contents of your IFrame to match the size the IFrame itself.

The EventMarker class has been extended to take an icon reference as a parameter. When a traffic event is parsed from the xml file it’s severity is […]

Flex: Degrafa demo update

I have updated the ‘Jess’ demo to use a higher vector count image. There are 103 vectors in the new image. You can adust the image in both the X and Y directions as well. To recap, I have converted an original jpg image to an SVG vectorised representation using Vector Magic. The SVG is […]

Flex: Vector Magic to Degrafa Example

My Sunday afternoon task was to take the promise of this post on the Degrafa website and put it into practise. The target was to take a source jpeg, convert it to SVG and then parse the SVG to generate Degrafa mxml which would match the original image. This is a picture of my cat […]
