构造器详细资料

WarpGrid

public WarpGrid(int rows,
                int cols,
                int w,
                int h)

方法详细资料

addRow

public void addRow(int before)

Add a new row to the grid. "before" must be in the range 1..rows-1. i.e. you can only add rows inside the grid.

addCol

public void addCol(int before)

Add a new column to the grid. "before" must be in the range 1..cols-1. i.e. you can only add columns inside the grid.

removeRow

public void removeRow(int r)

Remove a row from the grid.

removeCol

public void removeCol(int r)

Remove a column from the grid.

lerp

public void lerp(float t,
                 WarpGrid destination,
                 WarpGrid intermediate)

warp

public void warp(int[] inPixels,
                 int cols,
                 int rows,
                 WarpGrid sourceGrid,
                 WarpGrid destGrid,
                 int[] outPixels)

interpolateSpline
