...But "tukey(5e-1)" should be locale-independent so it is possible to re-add 'const char *apodization' member into CompressionLevels struct. The patch is attached. This will allow to easily change preset settings from "tukey(5e-1)" to "tukey(5e-1);partial_tukey(2);punchout_tukey(3)" or something like this. -------------- next part -------------- A non-text attachment was scrubbed...

Two things: 1) Shouldn?t we give Martijn van Beurden a mention for his great work on the "bartlett, bartlett_hann and triangle functions? and "New apodization functions partial_tukey and punchout_tukey? code? 2) There is a typo under ?Build system?: "buiuld systems?
