Constructor Detail

PixelImage

public PixelImage(int width,
          int height)

The constructor. Set up buffer.

Parameters:

height - the images height.

width - the images width.

Method Detail

public void setPixel(int x,
            int y,
            int red,
            int green,
            int blue)

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.

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,
