Re: [SIP-devel] Problem with color images

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

Very strange...

the very same example works with me:

A=3Dimread(SIPDIR+=EDmages/ararauna.jpg');

size(A)
 ans  =3D

  !   161.    200.    3. !


What version of scilab, SIP and operating system are you using?

That test was made under Linux with scilab CVS.
If you're using Linux, install the CVS version.

cheers,
Ricardo.
