Constructor Detail

ScalePerspectiveImageOp

public ScalePerspectiveImageOp(int w,
                               int h,
                               int x1,
                               int y1,
                               int w1,
                               int h1,
                               int rh1,
                               int ssx,
                               int ssy,
                               double p,
                               boolean reflect)

Parameters:

w - original width

h - original height

x1 - upper left hand corner

y1 - upper left hand corner ( when p=0 )

w1 - new width

h1 - new height at the middle

ssx - subsampling factor. =1 no subsampling. -1 means subsampling allowed, and will be picked automatically.

ssy - subsampling factor. =1 no subsampling. -1 means subsampling allowed, and will be picked automatically.

rh1 - extra height for the reflection

p - rockiness, similar to the tan of the angle of the top of the image. Zero means no perspective (flat).
