  org.opensourcephysics.display.MeasuredImage
      org.opensourcephysics.display2d.IntegerRaster

All Implemented Interfaces:

Dimensioned, Drawable, Measurable

public class IntegerRaster

extends MeasuredImage

implements Dimensioned

A IntegerRaster contains an array of integers where each integer representents an image pixel. Because the image created by a IntegerRaster cannot be resized, the image dimensions are the same as the dimensions of the integer array.

Constructor Detail

IntegerRaster

public IntegerRaster(int _nrow,
                     int _ncol)

Constructs IntegerRaster with the given size.

Parameters:

_nrow - the number of rows

_ncol - the number of columns

Method Detail

setBlock

public void setBlock(int row_offset,
                     int col_offset,
                     int[][] val)

Sets a block of lattice cells to new values.

Parameters:

row_offset -

col_offset -

val -

setRow

public void setRow(int row,
                   int col_offset,
                   int[] val)

Sets a row of lattice cells to new values.

Parameters:

row -

col_offset -

val -

setCol

public void setCol(int row_offset,
                   int col,
                   int[] val)

Sets a column of lattice cells to new values.

Parameters:

row_offset -

col -

val -

setCell

public void setCell(int _row,
                    int _col,
                    int val)

Sets a lattice cell to a new value.

getCell

public int getCell(int _row,
                   int _col)

Gets a lattice cell value.

Returns:

the cell value.

getInterior

public java.awt.Dimension getInterior(DrawingPanel panel)

Gets the dimension of the lattice in pixel units. Because Java does not support scaling of packed rasters, the image can only be translated.

Specified by:

getInterior in interface Dimensioned

Parameters:

panel -

Returns:

the dimension

draw

public void draw(DrawingPanel panel,
                 java.awt.Graphics g)

Draws the image and the grid.

Specified by:

draw in interface Drawable

Overrides:

draw in class MeasuredImage

Parameters:

panel -

g -
