Key Variables and Functions in ALEX

    In order to extend the functionality of ALEX, some information about
    the inner workings of the program must be provided. Here is contained
    a list of the important variables and functions used in ALEX.

Variables:  these are defined as gobal variables

    Clipboard    -    Contains data for the Undo function. Usually this is
                      a saved image from a previous call to setimage.

    Coords       -     Contains the coordinates for any measurements performed
                       on the current image.

    CutPaste     -     This is the cut and paste buffer for the cut, copy
                       and paste functions.

    Fname        -     Contains the current file name and extension.

    FullFname    -     Contains Fname preceeded by the path of the current
                       file.

    H            -     Contains the Nanoscope AFM header as read from the
                       current file.

    Handlefig    -     Contains a handle to the ALEX figure.

    Handleimg    -     Contains a handle to the image.

    Handleimgax  -     Contains a handle to the image axes.

    I            -     Contains the image matrix. All image operations should
                       be done directly on the image data.

    map          -     Contains the current colormap data.

    MapSize      -     Contains the size of the current colormap.

    readpath     -     Contains the current path from which all data
                       files will be read.

    savepath     -     Contains the current path to which all data files will be

                       read.



Functions: see the individual helps for the functions for the call protocols

    copyimage    -     Copies a mouse-defined area of the image to the global
                       variable CutPaste.

    cutimage     -     Copies a mouse-defined area of the current image to the
                       global variable CutPaste, and erases that area from the
                       image.

    getparameter -     Gets a specified parameter from the Nanoscope header of
                       the current image. This header is contained in the
                       variable H.

    getview      -     Returns the submatrix of the image matrix, I, which
                       corresponds to the current view.

    getviewmode  -     Returns the current view mode for the current image (eg.
                       TOPVIEW or TOPVIEW_INTERP).

    pasteimage   -     Copies the contents of the CutPaste variable to the
                       specified area of the current image.

    setimage     -     Replaces the current image with the specified image
                       matrix. All operations having to do with modifications to

                       the image should use this function.

    setparameter -     Writes a new value for a specified parameter to the
                       Nanoscope header of the current image. The header is
                       contained in the global variable H.

    setviewmode  -     Set the view mode for the current image.

    setzoomstatus -    Turns automatic zooming off and on.

    showimage    -     Displays the current image in the view mode returned by
                       getviewmode.
