        <div>Well, agreed to this.</div>

        </div>
        <div>However here a different approach:</div>
        <div><br>
        </div>
        <div>I wonder if it couldn't be helpful to connect Scilab with a
          native Image processing Programm...like Inkscape.</div>
        <div><br>
        </div>
        <div>Why trying to convert Scilab into a image processing tool,
          while there are dedicated programs for it?</div>
        <div><br>
        </div>
        <div>Yes I know: It might be better to have everything in one
          package, beeing independent from other Software.</div>
        <div>As I use IPD very much I'm glad to have this available.</div>
        <div><br>
        </div>
        <div>I just have to think about a discussion about one
          complaining about Images, trying to manage his images with
          MS-Word instead of using a proper Software.</div>
        <div><br>
        </div>
        <div><br>
        </div>
        <div>Basic Image processing functions like rotate, shift, etc.
          might be done using the "dos" command and Inkscape as well.</div>
      </div>

    Hi Philipp,<br>
    <br>
    I think we are not talking about the same kind of processing here.<br>
    Image processing in the context of Scilab is more opencv-like than
    inkscape-like.<br>
    I want to import into scilab an image (3*8bits RGB bmp, 3*32bits RGB
    bmp, 16bits grayscale TIFF, ...) and map it to the most relevant
    variable in scilab (HxWX3 hypermatrix of uint8 for HxW 8bitRGB bmp,
    ...), in order to do some number crunching on the data contained in
    the image.<br>
    It's not really cropping, rotating or some sort of "photoshoping"
    that I need, it's basically a way to "process" (as in signal
    processing).<br>
    <br>
    Cheers,<br>
    <br>
    Antoine<br>

                          <blockquote type="cite">I am worried, in
                            previous versions of scilab, I implemented a
                            medium project for scientific computing with
                            scilab at that time had many memory leaks
                            and had been a nightmare. With the new
                            updates that was fixed and this much better.
                            Â But now I am implementing another project
                            involving massive image processing. And the
                            three atoms for this, one does not work, one
                            does not load images but the manual says
                            they can do, and other charges but leak the
                            computer's memory and it took me longer
                            skirting the problem than implementing the
                            solution. And worse, because this the system
                            is much slower than it should. This atom
                            memory failure it has been known, however,
                            despite it make impraticable to use the atom
                            for medium and large projects, makes three
                            years that no one gets the bug. <a

                            There are high expectations with Scilab 6
                            and I believe we will have a much better
                            platform. But for what you know, in the
                            meantime we will run out of many atoms, and
                            this greatly reduces the possibility of
                            working in scilab. What is the future of
                            Scilab? For now, the impression I have is
                            that the atoms are abandoned and without the

                        </span> Hi,<br>
                        <br>
                        I think there are two issues here:<br>
                        <br>
                        1) The sad state of image processing toolbox
                        with Scilab. It's terrrible. Image processing
                        with Scilab is a nightmare. Every other language
                        I use is far better than Scilab in this area
                        (even extremely young language like Julia offers
                        a better experience. The 3 toolboxes are either
                        broken, unmaintained or difficult (or
                        impossible) to install. And the experience is
                        even worse under Linux (IPD for example requires
                        a very old version of opencv to be manually
                        installed under Linux which is a daunting task
                        for most user and which introduces many
                        compatibility issues with other softwares
                        relying on opencv).<br>
                        <br>
                        2) The lack of information on the life (or lack
                        of life) for a given atoms module. I know some
                        information is available on the atoms website,
                        but I've always found it difficult to determine
                        whether the package was long dead or under
                        active development. There are some long dead
                        modules that are still listed alongside with
                        actively maintained ones and that show excellent
                        rating. It's a bit confusing.<br>
                        <br>
                        Concerning the first issue, image processing
                        with scilab, I think a basic core image support
                        should be part of scilab.<br>
