Member Function Documentation

◆ color()

SkColor4f SkColor4Shader::color ( ) const

inline

Definition at line 67 of file SkColorShader.h.

67{ return fColor; }

◆ colorSpace()

sk_sp< SkColorSpace > SkColor4Shader::colorSpace ( ) const

inline

Definition at line 66 of file SkColorShader.h.

66{ return fColorSpace; }

◆ isConstant()

bool SkColor4Shader::isConstant ( ) const

inlineoverridevirtual

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

Reimplemented from SkShaderBase.

Definition at line 62 of file SkColorShader.h.

62{ return true; }

◆ isOpaque()

bool SkColor4Shader::isOpaque ( ) const

inlineoverridevirtual

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

Reimplemented from SkShader.

Definition at line 61 of file SkColorShader.h.

61{ return fColor.isOpaque(); }

◆ type()

ShaderType SkColor4Shader::type ( ) const

inlineoverridevirtual

Implements SkShaderBase.

Definition at line 64 of file SkColorShader.h.

64{ return ShaderType::kColor4; }
