I am Maryah and I am looking for an application wich can

open grafics of snapshot ( unix) in windows applications.... Can anybody help me?

If I understood correctly, you have used the "snapshot" applications in Unix to capture a part of your Self screen and now want to use this in a Windows application. When you capture the image, it is shown in the "image viewer" application. You can select "save as..." from the "file" menu, and can choose between several different formats for the resulting file.

I prefer to save my images in the GIF format, which can be easily viewed using any web browser (see the graphs that I captured directly from the Self screen at http://www.lsi.usp.br/~jecel/tiny.html). You can also use the JPEG format, but the image quality might not be as good.

Depending on your particular application, the TIFF format might be the easiest to use (I haven't tested it, but it is very likely that Microsoft Word can read these kind of images).

        I have another question... Does somobody know an operation

in Self to know when an object is a boolean object?

This kind of programming, where you are worried about the implementation details or kind of object that you are dealing with, is called "reflection". This is very powerful, but should be avoided whenever possible (an explanation about this would be too long to include here). Self includes special objects called "mirrors" that you can use for reflective programming. Just write:

reflect: anObject

to obtain a mirror object that reflects on "anObject". This will do what you want:

(reflect: anObject) inheritsFrom: (reflect: traits boolean)

Make sure you *really* need this before going this route....
