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.
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.
interpolateSpline
protected void interpolateSpline(float[] xKnots,
float[] yKnots,
int offset,
int length,
float[] splineY,
int splineOffset,
int splineLength)
interpolateSpline2
protected void interpolateSpline2(float[] xKnots,
float[] yKnots,
int offset,
float[] splineY,
int splineOffset,
int splineLength)
removeCol
public void removeCol(int r)
Remove a column from the grid.
removeRow
public void removeRow(int r)
Remove a row from the grid.
