 ColorSpace colorSpace)

Method Details

isOpaque

public boolean isOpaque()

Description copied from interface: Shader

Returns true if the shader is guaranteed to produce only opaque colors, subject to the Paint using the shader to apply an opaque alpha value. Subclasses should override this to allow some optimizations.

Specified by:

isOpaque in interface Shader

isConstant

public boolean isConstant()

Returns true if the shader is guaranteed to produce only a single color. Subclasses can override this to allow loop-hoisting optimization.

Specified by:

isConstant in interface Shader

r

public float r()

g

public float g()

b

public float b()

a

public float a()

getColorSpace

public ColorSpace getColorSpace()

ref

public void ref()

Description copied from interface: RefCounted

Increases the reference count by 1.

Specified by:

ref in interface RefCounted

unref

public void unref()

Description copied from interface: RefCounted

Decreases the reference count by 1.

Specified by:

unref in interface RefCounted
