RgbAdjustment

Kotlin |Java

@UnstableApi
public final class RgbAdjustment implements RgbMatrix

Scales the red, green, and blue color channels of a frame.

Summary

Nested types
`public final class RgbAdjustment.Builder` A builder for `RgbAdjustment` instances.

Public methods
`float[]`	`getMatrix(long presentationTimeUs, boolean useHdr)` Returns the 4x4 RGB transformation `matrix` to apply to the color values of each pixel in the frame with the given timestamp.
`boolean`	`isNoOp(int inputWidth, int inputHeight)` Returns whether a `GlEffect` applies no change at every timestamp.

abstract GlShaderProgram

toGlShaderProgram(Context context, boolean useHdr)

Returns a GlShaderProgram that applies the effect.

BaseGlShaderProgram

toGlShaderProgram(Context context, boolean useHdr)

Returns a GlShaderProgram that applies the effect.

public float[] getMatrix(long presentationTimeUs, boolean useHdr)

Returns the 4x4 RGB transformation matrix to apply to the color values of each pixel in the frame with the given timestamp.

Parameters
`long presentationTimeUs`	The timestamp of the frame to apply the matrix on.
`boolean useHdr`	If `true`, colors will be in linear RGB BT.2020. If `false`, colors will be in linear RGB BT.709. Must be consistent with `useHdr` in `toGlShaderProgram`.

Returns
`float[]`	The `RgbMatrix` to apply to the frame.

public boolean isNoOp(int inputWidth, int inputHeight)

Returns whether a GlEffect applies no change at every timestamp.

This can be used as a hint to skip this instance.

Parameters
`int inputWidth`	The input frame width, in pixels.
`int inputHeight`	The input frame height, in pixels.
