All PDL Users-
The PDL Development team is happy to announce
the PDL-2.4.7 release of PDL.
This is another point release with lots of
goodies and many bugs fixed.
This release could not have happened without
the hard work of developers: Chris Marshall,
David Mertens, Daniel Carrera, Henning Glawe,
Craig DeForest, Rob/Sisyphus, Derek Lamb,
Matthew Kenworth, and Shlomi Fish and the
feedback and contributions of many PDL users
and the PDL community in general.
Enjoy and Happy PDL-ing!
Chris Marshall
and the PDL Development Team
Release notes for PDL 2.4.7 --------------------------
General Notes:
* New requirements:
- perl version 5.8.x and higher
- OpenGL-0.63
- Convert::UU
* New 2-D image display routine: imag2d()
* pdl() constructor, a.k.a. PDL->new(), now
takes string arguments with either MATLAB type
concatenation syntax or PDL print output (for
easier cut-and-paste from PDL shell sessions).
* Improved text and comma separated value file
input via rcols(): faster and more flexible.
* A new PDL shell based on Devel::REPL (i.e.,
Moose technology). The new shell supports
more perl syntax (lexical variables and
packages), is more extensible (via a system
of plugins), and supports many forms of file
and variable completion.
Install Devel::REPL and give it a try!
User feedback welcome.
* More portability (builds on more platforms
with more features than ever).
* Many bugs fixed...
Highlights:
* General
OpenGL-0.63 is required for PDL::Graphics::TriD.
Convert::UU is required for PDL.
Karma is DEPRECATED and NOT SUPPORTED. Set
USE_KARMA=>1 in perldl.conf to force a build.
* New 2D Image Display Feature: imag2d()
See PDL::Graphics2D for documentation.
Add image pixel value display on mouse
click in imag2d window
Add keyboard command shortcuts for imag2d
(with placeholders)
Fix a number of imag2d() usabiilty bugs
* pdl() Constructor Can Take String Input
Allows use of MATLAB-style [ ; ] syntax
Allows cut-and-paste of printed pdl values
as input args for pdl()
* rcols/wcols Improvements
Much faster read times
Multiple columns can read into a single
pdl varible
Symmetric handling of perl and pdl
column data
Improved format support for CSV file input
* Enhanced PDL Shell (Version 2)
Based on Devel::REPL which must be installed
along with either Term::ReadLine::Perl or
Term::ReadLine::Gnu to use the pdl2 features.
Supports Term::ReadLine::Perl and Term::ReadLine::Gnu.
Upward compatable with the original PDL shell, perldl.
Adds completion and command line editing support
across all PDL platforms.
Adds support for current package and lexical variables.
Toggle default print output via the do_print attribute.
Default prompt for perldl and pdl2 is now 'pdl> '
help vars now shows results alphabetically
pdl2 now runs (falls back to) perldl if Devel::REPL
is not installed or if Term::ReadLine::(Perl|Gnu) is
not installed.
* Other Features
Fix wmpeg() to use ffmpeg to generate the
video (sf.net feature request #3010984).
Added tiled compressed image handling to rfits
Faster matrix multiply
Preliminary support for ENVI file format data

and warns of possible conflicts.
'use PDL' now loads PDL::Config by default.
PDL "as built" configuration is now saved to %PDL::Config
