PDL 2.4.6 is available on Sourceforge and CPAN. This is mainly a polishing release with bug fixes and documentation improvements. Highlights include
* Enhanced 2D and 3D graphics support * New 2D image display routine * OpenGL-0.62 now required for 3D graphics * Build fixes for many platforms Look for it at a CPAN mirror near you soon or download the source distribution directly from SourceForge.net: http://sourceforge.net/projects/pdl/files/PDL/2.4.6/PDL-2.4.6.tar.gz/download Enjoy and Happy New Yeara All! The PDL Developers Release notes for PDL 2.4.6 -------------------------- General Notes: * Mainly a bugfix and polishing release Highlights: * Improved 3D graphics and OpenGL functionality * imag2d() routine for multi-image (photo) display * Many fixes for Debian package release * Several little bugs fixed since PDL-2.4.5 * Fixed some issues with PDL convolution routines * Improved documentation and release notes and files * Padre and enhanced perldl shell integration begun Summary of Changes: * Improved 3D graphics and OpenGL functionality Perl OpenGL 0.62 is the minimum required version for PDL::Graphics::TriD to build. TriD now builds correctly for Mac OS X systems without X11 installed. Autoprobe for build of 3D graphics and the use of the Perl OpenGL library has been implemented. The default perldl.conf setting is to check. Improved multi-window support for PDL::Graphics::TriD display windows: the GLUT window ID is now part of the default window title for convenience, and redraws with multiple open TriD windows are handled correctly. * imag2d() routine for multi-image (photo) display REQUIRES: The Perl OpenGL TriD interface and FreeGLUT. IMPORTANT: Legacy X11 TriD is *not* supported! It is implemented in the imag2d.pdl file for autoloading via PDL::AutoLoader. To use, copy the imag2d.pdl file to somewhere in your PDLLIB path or add the location to your PDLLIB environment variable. It works with multiple, simultaneous, image windows and appears to work side-by-side with TriD graphics windows. After you have imag2d.pdl in your @PDLLIB list, you can use 'help imag2d' to get usage instructions and documentation. This implements the basic functionality planned regarding an improved imagrgb() routine. * Many fixes for Debian package release This should allow PDL-2.4.6 to be more readily released as a Debian packages. The general clean up involved improves PDL portability and robustness generally. * Several little bugs fixed since PDL-2.4.5 The number of history lines when you use Term::ReadLine::Perl with perldl are now set correctly to $PERLDL::HISTFILESIZE. The default value is 500. A number of minor internal fixes for portability and implementation improvements: - Add comment re fix for defined(%hash) usage - Fix annoying PGPLOT::HANDLE warning message - Replace GIMME by GIMME_V in Core.xs - Update to v3.14 of ppport.h portability Fixed MINUIT build problem where non-standard code was being generated which caused problems with rigorous compiler settings. This was SF bug #2524068. * Fixed a number of issues with PDL convolution routines conv1d() algorithm adjusted to match conv2D() and convolutionND(). Documentation on the exact computation being performed in conv1d() was added. Fixes bug #2630369 with fftconvolve(). It now gives the same results as conv1d(), conv2d(),.., except perhaps with respect to the boundary condition handling. * Improved documentation and release notes and files Updated PDL::FAQ. Lots of little changes to bring documentation in line with current PDL functionality. Volunteer editors and contributors always welcome! * Padre and enhanced perldl shell integration begun There is a new PDL-2.4.6/Padre/ subdirectory in the PDL source tree which contains work towards Padre integration and a 2nd generation, enhanced perldl shell for PDL. E.g. an *experimental* plug-in giving PDL::NiceSlice support to the Devel::REPL shell is included. See the Padre/README file for instructions to get you started. See the distribution Release_Notes and Changes files for more detail. _______________________________________________ Perldl mailing list [email protected] http://mailman.jach.hawaii.edu/mailman/listinfo/perldl
