ly.img.android.sdk.filter

Class ImageFilter

java.lang.Object

ly.img.android.sdk.configuration.AbstractConfig

ly.img.android.sdk.filter.ImageFilter

All Implemented Interfaces:

AbstractConfig.ImageFilterInterface, DataSourceInterface<AbstractConfig.BindData>

Direct Known Subclasses:

LutColorFilter, NoneImageFilter

public abstract class ImageFilter
extends AbstractConfig
implements AbstractConfig.ImageFilterInterface

Represents the Image-Filter base file. For Camera live Preview the filter is OpenGl Based but has also a Renderscript implementation to render final images in full resolution.
