correspond values

    Feb 24 2006 | 6:32 pm
    Hi Does anybody know how to correspond the location values of a grid to correspond it to the location of images that appear on a screen... Any idea of the object that I might use for that, or a hint?

      not quite clear on what you are looking to do, but I've found jit.gencoord to be very useful in describing and decoding grids...

      Peter thanks Iam looking into that. I am trying to correspond the location values from a preasurre sensitive board to the screen. Daniela

      Do you mean that you have a pressure sensitive grid with which you want to change some corresponding grid on the screen?

      Yes exactly the only thing is that I have two coming values preasurre and location.

      Ok, well it's still unclear what you want to do although I have an idea as to what your setup is. If you're just trying to correspond a pressure location to a screen location, then it should be quite simple to figure out how to map one to the other. Imagine you have a coordinate system for your mat and a coordinate system for your image. Getting one point on the map to correspond to one point on the screen is simply a matter of determining how the coordinates transform from one space to the other. Basically, figuring out relative orientation (is one flipped with respect to the other?), figuring out relative scale (is one bigger than the other?) etc. Your values should all follow the same transformation if you are dealing with 2 grids.

      Hello Thanks for the explanation and patch.. I am sorry that it took me a while to read the answer..but I am new to this mailing list and I am still confused between the mailing list and this list... Daniela
