It's probably worth sending an email to Isenburg to ask for the actual licensing restrictions of his stuff. It was developed under an NSF grant, so he may not have much choice but to allow it to be used in a BSD-like way. Traian From: discuss-boun...@l

Not sure about the BSD licensing part, but here are some cool TIN triangulators which are open source. This one (Streaming Delaunay) has BSD-like license, but may be overkill for what you need: http://www.cs.unc.edu/~isenburg/sd/ This one (FIST) has nebulous licensing (different for commerc

It is not possible to *prove* a mathematical relationship by example. One would have to study the set of all possible images in the world and make sure they have no loss in order to effectively prove the claim. On the other hand you can *disprove* it by providing a single counterexample. That i

JPEG2K supports lossless via a reversible wavelet transform with integral coefficients (which make it reversible, and so lossless). Here is a reference: http://www.ece.uvic.ca/~mdadams/publications/pacrim2001.pdf Traian From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL

It looks like nemesis stores geometry as ASCII text. Which means it would be SLOW to put stuff in and get stuff out of the database (atof and sprint are the, ahem, nemesis of speed). I got my information from reading the source file SQLiteDatabase.cpp (http://nemesis-code.googlecode.com/svn/tr

Antialiasing, when done wrong is just "making the edges intermediate colors". When done right it also involves subpixel positioning which improves not only the visual appearance but also the relative accuracy of lines -- i.e. visual weight is most correctly distributed over exact position of th

The builds I have been posting lately have GML enabled. The way to make sure is see if the OGRProvider.dll has a dependency on the Xerces dll. Of course it has never been tested... Traian -Original Message- From: [EMAIL PROTECTED] on behalf of Frank Warmerdam (Exte
