Constructor Detail

ImageBlend

public ImageBlend(int firstwidth,
                  int secondwidth)

Constructs a new Image Blend

Parameters:

firstwidth - The width of the first image

secondwidth - The width of the second image

Method Detail

DoBlend

public int[] DoBlend(int[] src1_1d,
                     int[] src2_1d,
                     float blend,
                     int width,
                     int height,
                     float oset,
                     float scale)

Applies the image Blend 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

blend - The blending factor a float from 0..1

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 containing the blended image

DoBlend

public int[] DoBlend(int[] src1_1d,
                     float constant,
                     float blend,
                     int width,
                     int height,
                     float oset,
                     float scale)

Blends the specified input image by the constant, also adds offset and applies scaling.

Parameters:

src1_1d - The input pixel array

constant - The constant value to blend every pixel in the input array with

blend - The blending factor a float from 0..1

width - width of the destination image in pixels

height - height of the destination image in pixels

oset - The offset value

scale - The scaling value

Returns:

A pixel array containing the blended image
