Plots the whole tree structure of the wavelet packet (WP) tree in a picture control. You can show the node information of path, position, or entropy on each node of the wavelet packet tree.

Inputs/Outputs

  • cnclst.png draw color —

    draw color specifies the color of the wavelet packet tree.

  • cu32.png text color —

    text color specifies the color of the node strings.

  • cu32.png BG color —

    BG color specifies the background color of tree plot.

  • cu32.png line color —

    line color specifies the color of the tree branches.

  • ccclst.png WP session —

    WP session specifies a reference to an existing wavelet packet structure.

  • cu64.png ref —

  • catrn.png t0 —

  • cdbl.png dt —

  • cu16.png display mode —

    display mode specifies the display mode of the node string in the decomposition tree.

  • cnclst.png draw area size —

    draw area size specifies the size of the area in the picture control in pixels to draw the tree structure display. Wire the Draw Area Size property of tree plot to this control.

  • ci32.png width —

    width specifies the width of the tree structure display in pixels.

  • ci32.png height —

    height specifies the height of the tree structure display in pixels.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • cnclst.png draw offset —

    draw offset specifies the coordinates of the left topmost pixel in tree plot.

  • ci32.png x offset —

    x offset specifies the x coordinate of node in tree plot.

  • ci32.png y offset —

    y offset specifies the y coordinate of node in tree plot.

  • icclst.png WP session out —

    WP session out returns a reference to an existing wavelet packet structure, which this VI can modify.

  • iu64.png ref —

  • iatrn.png t0 —

  • idbl.png dt —

  • ipict.png tree plot —

    tree plot returns the picture control that displays the tree structure.

  • i1dcclst.png node info —

    node info returns the position of each node in the wavelet packet tree and the associated location in tree plot.

  • inclst.png node —

    node returns the indexes of a node with respect to depth and position.

  • ii32.png depth —

    depth is the depth of the node, that is, its level in the tree.

  • ii32.png position —

    position is the position of the node in its level.

  • inclst.png location —

    location returns the coordinates of node in tree plot.

  • ii32.png x —

    x is the x-coordinate of node in tree plot.

  • ii32.png y —

    y is the y-coordinate of node in tree plot.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
