Class FastPixelSlowDefault

java.lang.Object

dev.brachtendorf.graphics.FastPixelImpl

dev.brachtendorf.graphics.FastPixelSlowDefault

All Implemented Interfaces:

FastPixel

public class FastPixelSlowDefault
extends FastPixelImpl

A fallback instance of fast pixel using a cached getRGB instance instead of the underlying buffer due to the fact that no other implementation currently is available. This allows to support all image formats but individual implementations should be replaced by faster alternatives in the future.

Constructor Detail

FastPixelSlowDefault

public FastPixelSlowDefault(BufferedImage bImage)

Constructs a fast pixel object with the underlying buffered image.

Note that calling this method may cause this DataBufferobject to be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).

Parameters:

bImage - The buffered image to extract data from

Since:

1.3.0 com.github.kilianB

Method Detail

getRGB

public int getRGB(int index)

getRGB

public int[][] getRGB()

Description copied from class: FastPixelImpl

Returns the rgb values of the entire image in an 2 d array in the default RGB color model(TYPE_INT_ARGB). There are only 8-bits of precision for each color component in the returned data when using this method. An ArrayOutOfBoundsException may be thrown if the coordinates are not in bounds.

Specified by:

getRGB in interface FastPixel

Overrides:

getRGB in class FastPixelImpl

Returns:

a 2d integer array containing the argb values of the image

getAlphaInternal

public int getAlphaInternal(int index)

Specified by:

getAlphaInternal in class FastPixelImpl

setAlpha

public void setAlpha(int index,
                     int newAlpha)

Description copied from interface: FastPixel

Set the alpha value. This method is a NOP if alpha is not supported.

Parameters:

index - the offset of the underlying array

newAlpha - the new alpha value in range [0-255]

setAlpha

public void setAlpha(int[][] newAlpha)

Description copied from class: FastPixelImpl

Set new alpha values for the entire picture

Specified by:

setAlpha in interface FastPixel

Overrides:

setAlpha in class FastPixelImpl

Parameters:

newAlpha - red values in range [0-255]

getRedInternal

public int getRedInternal(int index)

Specified by:

getRedInternal in class FastPixelImpl

setRed

public void setRed(int index,
                   int newRed)

Description copied from interface: FastPixel

Set the red value at the specified offset

Parameters:

index - the offset of the underlying array

newRed - the new red value in range [0-255]

setRed

public void setRed(int[][] newRed)

Description copied from class: FastPixelImpl

Set new red values for the entire picture

Specified by:

setRed in interface FastPixel

Overrides:

setRed in class FastPixelImpl

Parameters:

newRed - red values in range [0-255]

getGreenInternal

public int getGreenInternal(int index)

Specified by:

getGreenInternal in class FastPixelImpl

setGreen

public void setGreen(int index,
                     int newGreen)

Description copied from interface: FastPixel

Set the green value at the specified offset

Parameters:

index - the offset of the underlying array

newGreen - the new green value in range [0-255]

setGreen

public void setGreen(int[][] newGreen)

Description copied from class: FastPixelImpl

Set new green values for the entire picture

Specified by:

setGreen in interface FastPixel

Overrides:

setGreen in class FastPixelImpl

Parameters:

newGreen - red values in range [0-255]

getBlueInternal

public int getBlueInternal(int index)

Specified by:

getBlueInternal in class FastPixelImpl

setBlue

public void setBlue(int index,
                    int newBlue)

setBlue

public void setBlue(int[][] newBlue)

Description copied from class: FastPixelImpl

Set new blue values for the entire picture

Specified by:

setBlue in interface FastPixel

Overrides:

setBlue in class FastPixelImpl

Parameters:

newBlue - red values in range [0-255]

setAverageGrayscale

public void setAverageGrayscale(int[][] newGrayValue)

Description copied from interface: FastPixel

Set the gray values of the entire image.

Average grayscale: (R+G+B)/3

It is up to the inheriting class to decide how the gray value is reflected at the value level. If the image is still in rgb or argb mode the value of each individual channel will be set to the gray value

Specified by:

setAverageGrayscale in interface FastPixel

Overrides:

setAverageGrayscale in class FastPixelImpl

Parameters:

newGrayValue - to set the pixels to range [0 - 255]

getOffset

public int getOffset(int x,
                     int y)

Description copied from interface: FastPixel

Map the x and y values to the underlying one dimensional data array

Parameters:

x - the x coordinate

y - the y coordinate

Returns:

the corresponding 1d array index
