Method Details

initOriginCenter

public void initOriginCenter(Polygon2D_F64 polygon,
 int squaresWide)

Origin is defined as the dead center of the center square in the locator pattern. Thus the inner more square black square is from (-0.5, -0.5) to (0.5, 0.5)

Parameters:

polygon - Polygon which defines the square grid in image pixels

squaresWide - Number of squares wide the grid coordinate is inside the square

convert

public void convert(double gridX,
 double gridY,
 Point2D_F64 pixel)

Computes location of grid coordinate on the image in pixels
