Class SkewImage

java.lang.Object

pt.lsts.neptus.console.plugins.kml.SkewImage

public class SkewImage
extends java.lang.Object

Taken from http://www.javaxt.com/ by By Peter Borissow released under MIT Licence "Used to skew an image. Adapted from 2 image processing classes developed by Jerry Huxtable (http://www.jhlabs.com) and released under the Apache License, Version 2.0." Used to skew an image by updating the corner coordinates. Coordinates are supplied in clockwise order starting from the upper left corner. SkewImage skew = new SkewImage(this.bufferedImage); this.bufferedImage = SkewImage.setCorners(x0, y0, // UL x1, y1, // UR x2, y2, // LR x3, y3 // LL);

Method Detail

setCorners

public java.awt.image.BufferedImage setCorners(float x0,
                                               float y0,
                                               float x1,
                                               float y1,
                                               float x2,
                                               float y2,
                                               float x3,
                                               float y3)

Used to skew an image by updating the corner coordinates. Coordinates are supplied in clockwise order starting from the upper left corner. Skew skew = new Skew(this.bufferedImage); this.bufferedImage = skew.setCorners(x0, y0, x1, y1, x2, y2, x3, y3);

Parameters:

Returns:

transformSpace

protected void transformSpace(java.awt.Rectangle rect)

getOriginX

public float getOriginX()

getOriginY

public float getOriginY()

filterPixelsNN

protected java.awt.image.BufferedImage filterPixelsNN(java.awt.image.BufferedImage dst,
                                                      int width,
                                                      int height,
                                                      int[] inPixels,
                                                      java.awt.Rectangle transformedSpace)

transformInverse

protected void transformInverse(int x,
                                int y,
                                float[] out)

getRGB

public int[] getRGB(java.awt.image.BufferedImage image,
                    int x,
                    int y,
                    int width,
                    int height,
                    int[] pixels)

A convenience method for getting ARGB pixels from an image. This tries to avoid the performance penalty of BufferedImage.getRGB unmanaging the image.

setRGB

public void setRGB(java.awt.image.BufferedImage image,
                   int x,
                   int y,
                   int width,
                   int height,
                   int[] pixels)

A convenience method for setting ARGB pixels in an image. This tries to avoid the performance penalty of BufferedImage.setRGB unmanaging the image.

main
