[SIP-devel] more tests and corrections

[DRUEL J. <joc...@li...>]

Hi,
As I test SIP-0.3, I try to correct what goes wrong with me, and improve (a 
little) some things:

* imconv.sci: just added the correction syntax in the error message and added 
a warning that it does not work with colored pictures.

* mkfilter.sci: I just added an error message if the number of arguments is 
incorrect. I changed (a very little) the way to calculate the low-pass 
filters: with mask=mask/sum(mask): it's a bit more generic.

* unwrapl: it was working fine (thanks Ricardo). I added just an indication 
that the unwrapped phase is not in 0-1 range. I adapted the example of the 
man page.

* improfile: I added a lum_max (optional) parameter: the default is 255 (8bit 
image). It's only used to display profiles on the screen (because values in 
the profile are in 0-1 range). I prefer this solution to the one that 
consists of multiplying the profile by the (horizontal or vertical) size of 
the picture: it allows to make direct measurement on the screen. This 
multiplication coefficient is customizable by the user.
The man page was rewritten to explain this.

* each time, I tried to write an error function that also indicates what the 
user should have done.

* That's all for now (but I'd like to perform some other tests if I have some 
time: with the interf_demo mainly). 
I believe SIP-0.3.0 will be a great release.

Best regards
Jocelyn
