[SIP-devel] a new version for improfile

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

Hi,
I worked on improfile and I did 3 things:
1) a simplified version:
I suppressed the possibility to have just one of the profiles (either 
vertical or horizontal).
I don't think anybody needs this possibility. Tell me if I'm wrong.

The code is easier like this (and the easier=the better).

2) the function returns 2 matrix with the vertical and horizontal profiles

3) the gaussian interpolation: by giving option=2, we can now see the 
profiles and their gaussian interpolation.
I needed this functionnality because we work with laser beams: it's a way to 
see the quality of a laser.
You can try it with the image joined.
improfile(imread('laser1.jpg'),2)

This new version of improfile has a different number of arguments compared 
with the previous version (the argument "direction" disappears). I hope, it's 
not a pb for anybody.

For the gaussian interpolation, I created a function gaussprofile: it's a 
separate function (and not a sub-function of improfile), simply because 
scilab-2.6 does not support sub-functions.

I noted a small pb: if I call improfile with no graphical window present, I 
have the title "left click to select..."
If a graphicalwindow is already present, I see the image, but I don't have 
this title (I have no title in fact). Well, not very important, just a bit 
strange.



Best regards.
Jocelyn
