Field Detail

FILTER_FIR_COEFFS

protected static final float[] FILTER_FIR_COEFFS

Deprecated.

pixels

public final int[] pixels

Deprecated.

An array of pixels. This can be in RGBA or grayscale. By default, it is RGBA, but if the toGrayScale() method has been called, each pixel will be in the range of 0-255 grayscale.

width

public final int width

Deprecated.

Width of the image, in pixels.

height

public final int height

Deprecated.

Height of the image, in pixels.

npix

public final int npix

Deprecated.

Total number of pixels in the image (arrayWidth*arrayHeight).

aspectRatio

public final float aspectRatio

Deprecated.

Aspect ratio of the image (arrayWidth/arrayHeight).

LOG

private static final Logger LOG

Deprecated.

Constructor Detail

PixelImage

public PixelImage(int[] pixels,
                  int width,
                  int height)

Deprecated.

Construct a new PixelImage object from an array of pixels.

Parameters:

pixels - An array of pixels. This can be in RGBA or grayscale. By default, it is RGBA, but if the toGrayScale() method has been called, each pixel will be in the range of 0-255 grayscale.

width - Width of the image, in pixels.

height - Height of the image, in pixels.

PixelImage

public PixelImage(Image image)

Deprecated.

Construct a new PixelImage object from an Image.

Parameters:

image - An Image from which to get the pixels. The image must be fully loaded. Use a MediaTracker to ensure this, if necessary.

Method Detail

rgbToImage

public Image rgbToImage(int[] rgbPixels,
                        int width,
                        int height,
                        Component comp)

Deprecated.

getPixelIndex

public final int getPixelIndex(int x,
                               int y)

Deprecated.

Get the index of a pixel at a specific x,y position.

Parameters:

x - The pixel's x position.

y - The pixel's y position.

Returns:

The pixel index (the index into the pixels array) of the pixel.

getPixel

public final int getPixel(int x,
                          int y)

Deprecated.

Get the value of a pixel at a specific x,y position.

Parameters:

x - The pixel's x position.

y - The pixel's y position.

Returns:

The value of the pixel.

rgbToGrayScale

private static int rgbToGrayScale(int pix)

Deprecated.

toGrayScale

public final void toGrayScale(boolean normalize)

Deprecated.

Convert all pixels to grayscale from RGB or RGBA. Do not call this method if the pixels are not currently RGB or RGBA.

Parameters:

normalize - true to normalize the image after converting to grayscale, such that the darkest pixel in the image is all black and the lightest pixel in the image is all white.

grayScaleToRGB

public final int[] grayScaleToRGB(int[] pixels)

Deprecated.

filter

public final void filter()

Deprecated.

filter

public final void filter(int[] pixels,
                         int width,
                         int height)

Deprecated.
