Method Detail

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;
        }

filter

protected void filter(CoreImage src,
                      CoreImage dst)

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.
