Method Detail

rectStretch

public float[][] rectStretch()
RectStretch enlarges or diminishes a source rectangle of a bitmap to a destination rectangle. The source rectangle is selected by the two points (xs1,ys1) and (xs2,ys2), and the destination rectangle by (xd1,yd1) and (xd2,yd2). Since readability of source-code is wanted, some optimizations have been left out for the reader: It�s possible to read one line at a time, by first stretching in x-direction and then stretching that bitmap in y-direction. Entry: xs1,ys1 - first point of source rectangle xs2,ys2 - second point of source rectangle xd1,yd1 - first point of destination rectangle xd2,yd2 - second point of destination rectangle
