public PixelImage(int width,
                  int height)

The constructor. Set up buffer.

Parameters:

height - the images height.

width - the images width.

Method Detail

setPixel

                     int y,
                     int red,
                     int green,
                     int blue)

sets a pixel to a specific color.

Parameters:

x - the pixels x value.

y - the pixels y value.

red - the pixels red value.

green - the pixels green value.

blue - the pixels blue value.

setPixel

public void setPixel(int x,
                     int y,
                     java.awt.Color color)

sets a pixel to a specific color.

x - the pixels x value.

y - the pixels y value.

color - the pixels color.

getProducer

public java.awt.image.ImageProducer getProducer()

gets the ImageProducer for this image.

Returns:

the ImageProducer for this image.

getPixelBuffer

public int[] getPixelBuffer()

gets the pixel buffer of this image.

Returns:

the pixel buffer.

drawLine

public void drawLine(int x0,
                     int y0,
                     int x1,
                     int y1,
                     int red,
                     int green,
                     int blue)

draws a line in the image. The incremental line scan-conversion algorithm is used (see "Computer Graphics"; Foley, vanDam,Feiner,Hughes). (x0,y0) is the starting point, (x1,y1) the ending point.

clearAll

public void clearAll()

sets all pixels to black.
