Constructor Detail

FastPixelInt

public FastPixelInt(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(int x,
                  int y)

Returns an integer pixel 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.

Parameters:

x - the X coordinate of the pixel from which to get the pixel in the default RGB color model

y - the Y coordinate of the pixel from which to get the pixel in the default RGB color model

Returns:

an integer pixel in the default RGB color model and default sRGB colorspace.

Since:

1.3.0 com.github.kilianB

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]

getRedInternal

protected 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 x,
                   int y,
                   int newRed)

Set the red value of the specified pixel

Parameters:

x - The x coordinate of the images' pixel

y - The y coordinate of the images' pixel

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

Since:

1.3.0 com.github.kilianB

getGreenInternal

protected 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]

getBlueInternal

protected int getBlueInternal(int index)

Specified by:

getBlueInternal in class FastPixelImpl

setBlue

public void setBlue(int index,
                    int newBlue)

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
