Method Detail

get

public Filter get(int i)

add

public void add(Filter filter)

add

public void add(int i,
                Filter filter)

set

public void set(int i,
                Filter filter)

remove

public void remove(int i)

size

public int size()

getX

public int getX()

Description copied from class: Filter

Gets the x offset the output image should display relative to the input.

Overrides:

getX in class Filter

getY

public int getY()

Description copied from class: Filter

Gets the y offset the output image should display relative to the input.

Overrides:

getY in class Filter

getWidth

public int getWidth()

Description copied from class: Filter

Gets the width of the output of this filter. By default, the width is the same as the input's width.

Overrides:

getWidth in class Filter

getHeight

public int getHeight()

Description copied from class: Filter

Gets the height of the output of this filter. By default, the height is the same as the input's height.

Overrides:

getHeight in class Filter

isOpaque

public boolean isOpaque()

Description copied from class: Filter

Returns true if the output of this filter is opaque. By default, the output is opaque if the input is opaque.

Overrides:

isOpaque in class Filter

update

public void update(int elapsedTime)

Description copied from class: Filter

Updates the filter. The default method does nothing.

Overrides:

update in class Filter

filter

protected void filter(CoreImage input,
                      CoreImage output)

Description copied from class: Filter

Performs this filter on the input image onto the specified output image.

This method is called from Filter.getOutput() if Filter.isDirty() returns true. The output image will be the same dimensions as (Filter.getWidth() x Filter.getHeight(). Implementors must ensure that every pixel in output is drawn.

copy

public Filter copy()

Description copied from class: Filter

Creates a copy of the Filter for another Sprite to use. The input filter is also copied. The properties of the copy, if any, will be bound to the original filter's properties.

This method is used by the Sprite class. Most apps will not need to call this method.

Subclasses should bind all properties of the cloned object using bindWithInverse(). For example, for the HSBAdjust filter:

        public Filter copy() {
            HSBAdjust copy = new HSBAdjust();
            copy.hue.bindWithInverse(hue);
            copy.brightness.bindWithInverse(brightness);
            copy.saturation.bindWithInverse(saturation);
            return copy;
        }
