Constructor Detail

public RawScale8d(@NotNull
                  int[] imageData,
                  int dataWidth,
                  int dataHeight)

Creates a new instance.

Parameters:: imageData - the source image data to process; dataWidth - the width of the source image; dataHeight - the height of the source image

Method Detail

@NotNull
public int[] getScaledData()

Returns the scale image data. Note this is the method that does the work so it might take some time to process.

Returns:: an array of pixels 64 times smaller than the input array containing the scaled down image

private int getSourcePixel(int x,
                           int y)

Gets a pixel from the source image.

Parameters:: x - the x location of the pixel to retrieve; y - the y location of the pixel to retrieve
Returns:: the pixel value at the specified location

private void process(int x,
                     int y)

Processes a specific destination pixel.

Parameters:: x - the x location in the source image of the pixel to process; y - the y location in the source image of the pixel to process

private void setDestPixel(int x,
                          int y,
                          int p)

Sets a pixel in the destination image data.

Parameters:: x - the x location of the pixel to set; y - the y location of the pixel to set; p - the value of the pixel to set
