Member Function Documentation

int halftoner::Stucki::halftoneToLeft (  float *    source,
int    i,
int    j,
int    offset,
int    width,
int    height,
int    threshold
)  throw () [protected, virtual]
 

Perform the algorithm for one pixel and transfering the error on the left.

Parameters:
source  the source for pixel intensity.
i  the column position of the current pixel.
j  the row position of the current pixel.
offset  the index of the pixel in source.
width  the width of the image.
height  the height of the image.
threshold  the threshold of the algorithm.
Returns :
the intensity value of the new pixel.
