Constructor Detail

ImageGraphics

public ImageGraphics(java.lang.String backGroundFilePath,
                     java.lang.String title,
                     int xPositionOffset,
                     int yPositionOffset)

Method Detail

setPixelBW

public void setPixelBW(int x,
                       int y,
                       int intensity)

Sets a grayscale pixel, does not sets values for invalid pixels outside the screen. Does not repaint the screen either because it is slow. If required, please call Component.repaint() if needed after you have updated all the pixels you need.

Parameters:

x -

y -

intensity -

setPixelsBW

public void setPixelsBW(int[][] pixels)

Sets an array of grayscale pixels (from 0 to 255) and displays them

Parameters:

pixels -

setPixelsColor

public void setPixelsColor(java.awt.Color[][] pixels)

Sets an array of pixels of Color and displays them

Parameters:

pixels -

getPixelBW

public int getPixelBW(int x,
                      int y)

Gets a single pixel from the background image and returns its grayscale value

Parameters:

x -

y -

Returns:

getPixelsBW

public int[][] getPixelsBW()

Gets the array of the pixels (which have been converted to grayscale if required)

Returns:

The arrays of gray pixels

getPixelsColor

public java.awt.Color[][] getPixelsColor()

Gets the array of the pixels as Colors (see #Color)

Returns:

The arrays of pixels

convertToGray

public static java.awt.Color[][] convertToGray(java.awt.Color[][] c)

Converts a color array to a black-or-white array

Parameters:

c - The color array

Returns:

The array converted to BW

convertToGrayInt

public static int[][] convertToGrayInt(java.awt.Color[][] c)

Converts a color array to a black-or-white array

Parameters:

c - The color array

Returns:

The array converted to BW

paint

public void paint(java.awt.Graphics g)

Paint method

Overrides:

paint in class java.awt.Window

main

public static void main(java.lang.String[] args)
