Our reliance on C library POSIX time routines to (1) convert from +broken-down time to time-epoch, (2) to convert from time-epoch to +broken-down time, and (3) to format results with strftime have proved +problematic for non-C languages which have time routines of variable +quality. Also, it is not clear that even the POSIX time routines are +available on Windows. So we have plans afoot to implement high-quality +versions of (1), (2), and (3) with additional functions to get/set the epoch +in the PLplot core library itself. These routines should work on all C +platforms and should also be uniformly accessible for all our language +bindings. + +WARNING..... Therefore, assuming these plans are implemented, the present +part of our date/time PLplot API that uses POSIX time routines will be +changed. + 2.7 Alpha value support PLplot core has been modified to support a transparency or alpha value This was sent by the SourceForge.net collaborative development platform, the world's largest Open Source development site. |
