Constructor Summary

ImageDiv(int firstwidth, int secondwidth)
Constructs a new ImageDiv

Method Summary

int[]	doDiv(int[] src1_1d, float constant, int width, int height, float oset, float scale, boolean reverse) Divides the specified input image by the constant, also adds offset no need for scaling in this example.
int[]	doDiv(int[] src1_1d, int[] src2_1d, int width, int height, float oset, float scale, boolean reverse) Applies the image Div operator on the specified image arrays, with the specified offset and scale value

Constructor Detail

ImageDiv

public ImageDiv(int firstwidth,
                int secondwidth)

Constructs a new ImageDiv

Parameters:

firstwidth - The width of the first image

secondwidth - The width of the second image

Method Detail

doDiv

public int[] doDiv(int[] src1_1d,
                   int[] src2_1d,
                   int width,
                   int height,
                   float oset,
                   float scale,
                   boolean reverse)

Applies the image Div operator on the specified image arrays, with the specified offset and scale value

Parameters:

src1_1d - The first source image as a pixel array

src2_1d - The second source image as a pixel array

width - width of the destination image in pixels

height - height of the destination image in pixels

oset - The offset value

scale - The scale value

reverse - Reverse the order of the division

Returns:

A pixel array containing one image divided by the other

doDiv

public int[] doDiv(int[] src1_1d,
                   float constant,
                   int width,
                   int height,
                   float oset,
                   float scale,
                   boolean reverse)

Divides the specified input image by the constant, also adds offset no need for scaling in this example.

Parameters:

src1_1d - The input pixel array

constant - The constant value to divide every pixel in the input array by

width - width of the destination image in pixels

height - height of the destination image in pixels

oset - The offset value

scale - The scale value

Returns:

A pixel array of the input array divided by the constant
