Method Detail

get

public int get()

Description copied from class: AbstractLinearImage

retrieve current pixel empty

Specified by:

get in interface Image

Specified by:

get in class AbstractLinearImage

Returns:

current pixel empty

put

public void put(int value)

Description copied from class: AbstractLinearImage

save pixel to current position

Specified by:

put in interface Image

Specified by:

put in class AbstractLinearImage

chisel

public Image chisel(int fromX,
                    int fromY,
                    int width,
                    int height)

Description copied from interface: Image

chisel out sub-image out of original one. be careful with dimensions - no internal checks are done. Operation works in place and no data is copied.

Parameters:

fromX - subimage origin X

fromY - subimage origin Y

width - subimage width

height - subimage height

Returns:

image region as image

toString

public String toString()

Overrides:

toString in class AbstractLinearImage
