DSingleApplication - Open source rewrite of commercial Trolltech QtSingleApplication class

The implementation is quite different from what is described in trolltech documetation for QtSingleApplication. DSingleApplication uses tcp sockets to test/open a port in a range and then sed a message to that port and expects a correct answer, if it's correct then the app is running and we can talk to it.
This class is designed for Qt 4.

Resize - Interpolation routines for vectors and matrices

C++ Template based interpolation for vectors and matrices (images). Template types define data and computation precision. The library provides several interpolation filters and allows simple increments. Embedded filters are: Point, Box, Triangle, Hermite, Hanning, Hamming, Blackman, Gaussian, Cubic, Quadratic, Catrom, Mitchell, Lanczos, Bessel, Sinc, Blackman-Bessel, Blackman-Sinc.

DRegExp - extension of QRegExp providing group syntax (from Python)

DRegExp extends QRegExp with python's group syntax (?P<name>...) and accessible via QHash: (?P<name>...) Similar to regular parentheses, but the substring matched by the group is accessible via the symbolic group name name. Group names must be valid Python identifiers, and each group name must be defined only once within a regular expression. A symbolic group is also a numbered group, just as if the group were not named. So the group named 'id' in the example above can also be referenced as the numbered group 1.

For example, if the pattern is (?P<id>[a-zA-Z_]\w*), the group can be referenced by its name in arguments to methods of match objects, such as group('id').

Ex: Say you want to parse file name and get particular values with names:
fileName: "2007-2-5.tif"
pattern: "(?P<year>[0-9]*)-(?P<month>[0-9]*)-(?P<day>[0-9]*)"
this generates output hash: { year: 2007, month: 2, day: 5 }
