High-Definition Semantic Maps (Part III)

(continued from Part II)

This week I have toyed around with ways to zoom in and out of the map. After some experimentation I ended up with Seadragon, a Microsoft acquisitioned technology.

Try it out yourself.

Recipe: Converting PDF Documents Into PNG

In a little side-project involving DeepZooming documents I needed to convert PDF documents into images, and that with a controllable quality.

Of course, the program convert (part of the trusty ImageMagick library) can do that:

convert paper.pdf paper.png

It will not produce a single PNG, though, but one for each page, numbering them through.
