Constructor Detail

VecImg

public VecImg(JPiv jpiv,
              java.lang.String pathname)

Creates a new instance of VecImg

Parameters:

jpiv - The parent component.

pathname - The pathname of the UTF-8 file containing vector data.

Method Detail

getAsPlanarImage

public javax.media.jai.PlanarImage getAsPlanarImage()

Returns the data as a Planar Image

Returns:

The PlanarImage.

drawIntoVectorGraphicsFile

public void drawIntoVectorGraphicsFile(java.lang.String filename,
                                       java.lang.String format)

Export the vector plot in a vector based format like eps, pdf, svg etc.

Parameters:

filename - the filename

format - one of the following format strings: "eps", "pdf", "svg", "emf", or "swf"

getFilename

public java.lang.String getFilename()

Returns the name of the data file.

Returns:

The filename (not the pathname).

getVectorAt

public double[] getVectorAt(int x,
                            int y)

Get the vector at a point x, y. Gets the vector that is closest to a given point x, y.

Parameters:

x - The x coordinate in pixel (zero at upper left corner).

y - The y coordinate in pixel (zero at upper left corner).

Returns:

A single line of the PIV data.

getPivData

public PivData getPivData()

Get the PIV data.

Returns:

The data.

setShapeList

public void setShapeList(java.util.ArrayList<java.awt.Shape> shapeList)

Copy a list of shapes into the VecImg. The shapes are drawn at the next call of getAsPlanarImage() or drawIntoVectorGraphicsFile().

Parameters:

shapeList - A list of shapes.
