readImage

public static final java.awt.image.BufferedImage readImage(java.io.File f)
                                                    throws java.io.IOException

Returns a bufferedImage made from the file, can return null!

Throws:

java.io.IOException

scaleImage

public static java.awt.image.BufferedImage scaleImage(java.awt.image.BufferedImage im,
                                                      java.awt.Dimension destImageSize,
                                                      boolean preserveAspectRatio)

createBufferedImage

public static java.awt.image.BufferedImage createBufferedImage(int x,
                                                               int y,
                                                               int typeHint)

returns a BufferedImage of the desired size, it may use the typeHint but is not guaranteed to do so. This utility method is provided for lentikit as a central place for trying out different types of BufferedImage to evaluate performance and memory usage. In addition it checks for OutOfMemoryError and displays a JOptionPane dialog, since buffered images are far and away the most greedy users of memory creating a BufferedImage is the most likely time to run out of memory.

inchesToMeters

public static double inchesToMeters(double inches)

Simple method to convert incehs to Meters

saveImageAsPNG

public static void saveImageAsPNG(java.awt.image.BufferedImage image,
                                  java.lang.String filename)

Saves the image in PNG format to the specified file

saveImageAsPNG

public static void saveImageAsPNG(java.awt.image.BufferedImage image,
                                  java.io.File saveTo)

Saves the image in PNG format to the specified file
