public GlobalImageUtilities()

Method Detail

getInstance

public static GlobalImageUtilities getInstance()

Gets an instance of the image utilities

Returns:

An instance of the image utilities

init

public void init(javax.swing.JPanel owner)

Sets the owning drawing area for images

Parameters:

owner - The drawing area of the application

getBufferedImage

public java.awt.image.BufferedImage getBufferedImage(java.lang.String entry)

Create Image from a file, then turn that into a BufferedImage. This function also saves the image in a hashtable. Note: ImageIO makes everything go 5 times slower, creates unoptimized BufferedImage?

Returns:

A loaded image

getBufferedImage

public java.awt.image.BufferedImage getBufferedImage(java.lang.String entry,
                                                     int width,
                                                     int height)

Create Image from a file, then turn that into a BufferedImage. This function also saves the image in a hashtable. Note: ImageIO makes everything go 5 times slower, creates unoptimized BufferedImage?

Returns:

A loaded image

getStaticBufferedImage

public static java.awt.image.BufferedImage getStaticBufferedImage(int width,
                                                                  int height,
                                                                  int type)

flipImageVertically

public java.awt.image.BufferedImage flipImageVertically(java.lang.String entry,
                                                        java.awt.image.BufferedImage image)

Flips the imge vertically and returns the new image

Parameters:

image - the image to be fliped

Returns:

the fliped image

flipImageHorizontally

public java.awt.image.BufferedImage flipImageHorizontally(java.lang.String entry,
                                                          java.awt.image.BufferedImage image)

Flips the imge horizontally and returns the new image

Parameters:

image - the image to be fliped

Returns:

the fliped image

waitForImage

public static boolean waitForImage(java.awt.Image image)

Take an Image associated with a file, and wait until it is done loading. Just a simple application of MediaTracker. If you are loading multiple images, don't use this consecutive times; instead use the version that takes an array of images.

Parameters:

image - The image to wait on

Returns:

True if the load succeeded

waitForImages

public boolean waitForImages(java.awt.Image[] images)

Take some Images associated with files, and wait until they are done loading. Just a simple application of MediaTracker.

Parameters:

images - The images to wait on

Returns:

True if succeeded

getAvailableImages

public java.util.Enumeration getAvailableImages()

Gets the available loaded images

Returns:

An enumeration of the images paths

getAvailableFlippedVerticallyImages

public java.util.Enumeration getAvailableFlippedVerticallyImages()

Gets the available images that has been flipped vertically

Returns:

An enumeration of the images paths

getAvailableFlippedHorizontallyImages

public java.util.Enumeration getAvailableFlippedHorizontallyImages()

Gets the available images that has been flipped horizontally

Returns:

An enumeration of the images paths

line

public static java.util.Vector line(java.awt.Point p1,
                                    java.awt.Point p2)

drawString

public static void drawString(java.awt.Graphics2D g,
                              java.awt.Point middleTileScreenCoord,
                              java.lang.String str,
                              java.awt.Color color)

A static function to draw a string in a graphics context.

Parameters:

g - the Graphics2D context

middleTileScreenCoord - the coordinate on the screen where the middle of the string should be

str - the string to be drawn

color - the color of the string
