[SIP-devel] New devel release

[Ricardo F. <rf...@if...>]

In this release, there are new functions to convert RGB to/from HSV
images and colormaps. The Radon transform is now available. We also
fixed C functions with respect of truecolor images, by using Scilab's
new hypermatrix structure. Therefore this version now works with
Scilab 3.0. There are many other changes, making this a strong
candidate for the next SIP stable version. Download the new version at
http://siptoolbox.sf.net/devel

CHANGES
   + NEW hsv2rgb and rgb2hsv functions to convert between RGB images
     to HSV colorspace images. It also works for colormaps.  (thx.
     Sandro da Silva)
   + NEW radon and iradon functions (by Leandro Estrozi)
   + FIX regarding truecolor images in imwrite, imread and mogrify
     functions, by using scilab's new hypermatrix structure.
   + NEW sip_set_verbose, sip_quiet and sip_wordy functions to adjust
     the messaging level issued by sip routines. For instance, this
     may be used to stop imread and mogrify from issuing verbose
     messages, which are very annoying when these functions are used
     inside loops.
   + NEW sip_setenv to set environment variables.
   + unwrapl and unwrapp functions are now coded in C (by Jocelyn
     Druel). unwrapl now returns the unwrapped_phase and the
     phase_jumps to be consistent with the unwrapp function.
   + INCOMPATIBLE: improvements to imxprofile, new parameters
   + NEW threshold parameter for unwrapp
   + improvements to the interferometry GUI - Gamma correction on
     colormaps, use of imxprofile instead of improfile, and more.
   + INCOMPATIBLE: function angle changed to "getangle" because
     "angle" is too simple and often conflicts with user variables.
   + dummy builder.sce file so that Scilab includes SIP in the
     toolboxes menu (thx. Enrico Segre).
   + many fixes and improvements to help pages

Compilation and installation is suited for Linux, but should
workcorrectly in other unix systems. I use Slackware Linux 9.1.
Please report to the list any problems that you see with SIP in other
distros.

You shall install the new SIP version over the older ones
without problems, but if you want, you can remove the old version
like this: in the unix shell, change dir to the old SIP-dev then type
the following:

prompt# make uninstall

Also please comment out any "exec ...loader.sce" instructions from
your ".scilab" startup file before installing a new version.

Enjoy!
Ricardo.
