open fun apply(source: Array<ColorBuffer>, target: Array<ColorBuffer>, clip: Rectangle? = null)

Applies a filter operation using the given source and target arrays of ColorBuffer. Optionally, a clipping rectangle can be used to define the region for the filter operation.

fun apply(source: Array<ColorBuffer>, target: ColorBuffer, clip: Rectangle? = null)

Applies a filter operation using the given source array of ColorBuffer and the target ColorBuffer. Optionally, a clipping rectangle can be used to define the region for the filter operation.

fun apply(source: Array<ColorBuffer>, target: RenderTarget, clip: Rectangle? = null)

Applies a filter operation using the given source and target using a shader program. Optionally, a clipping rectangle can be used to define the region for the filter operation. Custom shader parameters are applied where applicable.

fun apply(source: ColorBuffer, target: Array<ColorBuffer>, clip: Rectangle? = null)

Applies a filter operation using the given source ColorBuffer and target array of ColorBuffer. Optionally, a clipping rectangle can be used to define the region for the filter operation.
