Constructor Detail

Render

public Render()

Construct an instance. The initial colormap used to render images is 256 grayscale.

Method Detail

addStripe

public void addStripe(int[] colors)

Add a vertical stripe.

Parameters:

colors - The colors of the pixels in the vertical stripe.

clearData

public void clearData()

Clear the render object of any image data.

getColormap

public int[][] getColormap()

Get the current colormap.

getXIncrement

public double getXIncrement()

Get the x increment.

getXOffset

public double getXOffset()

Get the x offset.

getYIncrement

public double getYIncrement()

Get the y increment.

getYOffset

public double getYOffset()

Get the y offset.

samplePlot

public void samplePlot()

Create a sample image.

Overrides:

samplePlot in class PlotBox

setColormap

public void setColormap(int[][] colormap)

Set the colormap. The user needs to give a 3-by-256 integer array as a colormap.

Parameters:

colormap - The colormap used to render images.

setXIncrement

public void setXIncrement(double xIncrement)

Set the x increment.

Parameters:

xIncrement - The increment in units of the x-axis of each stripe.

setXOffset

public void setXOffset(double xOffset)

Set the x offset.

Parameters:

xOffset - The starting value of the x-axis.

setYIncrement

public void setYIncrement(double yIncrement)

Set the y increment.

Parameters:

yIncrement - The increment in units of the y-axis of each patch within each stripe.

setYOffset

public void setYOffset(double yOffset)

Set the y offset.

Parameters:

yOffset - The starting value of the y-axis.

_drawPlot

protected void _drawPlot(java.awt.Graphics graphics,
                         boolean clearfirst)

Render the data.

Overrides:

_drawPlot in class PlotBox

Parameters:

graphics - The graphics context.

clearfirst - If true, clear the image before proceeding.
