Method Detail

warp

public static java.awt.image.BufferedImage warp(java.awt.image.BufferedImage srcImg,
                                                java.awt.Dimension targetDim,
                                                ImageWarp.PointTransform invTransform,
                                                ImageWarp.Interpolation interpolation)

Warp an image.

Parameters:

srcImg - the original image

targetDim - dimension of the target image

invTransform - inverse transformation (translates pixel coordinates of the target image to pixel coordinates of the original image)

interpolation - the interpolation method

Returns:

the warped image

getSharedArray

private static java.lang.Object getSharedArray(java.awt.image.BufferedImage srcImg)

getColor

private static int getColor(int x,
                            int y,
                            java.awt.image.BufferedImage img,
                            java.lang.Object sharedArray)
