Member Enumeration Documentation

◆ shader_type

enum fastuidraw::PainterBlendShader::shader_type

Enumeration to specify how blend shader operates.

Enumerator
single_src	Indicates blending is via fixed function blending with single source blending.
dual_src	Indicates blending is via fixed function blending with dual source blending.
framebuffer_fetch	Indicates blending is via framebuffer fetch.
number_types	The number of different types of valid shader_type values; also used to indicate an invalid value.

Definition at line 43 of file painter_blend_shader.hpp.

Constructor & Destructor Documentation

◆ PainterBlendShader() [1/2]

fastuidraw::PainterBlendShader::PainterBlendShader	(	enum shader_type	tp,
		unsigned int	num_sub_shaders = `1`
	)

inlineexplicit

Ctor for creating a PainterBlendShader which has multiple sub-shaders. The purpose of sub-shaders is for the case where multiple shaders have almost same code and those code differences can be realized by examining a sub-shader ID.

Parameters

tp	the "how" the blend shader operates
num_sub_shaders	number of sub-shaders

Definition at line 79 of file painter_blend_shader.hpp.

◆ PainterBlendShader() [2/2]

fastuidraw::PainterBlendShader::PainterBlendShader	(	reference_counted_ptr< PainterBlendShader >	parent,
		unsigned int	sub_shader
	)

inline

Ctor to create a PainterBlendShader realized as a sub-shader of an existing PainterBlendShader

Parameters

parent	parent PainterBlendShader that has sub-shaders
sub_shader	which sub-shader of the parent PainterBlendShader

Definition at line 91 of file painter_blend_shader.hpp.

Member Function Documentation

◆ type()

enum shader_type fastuidraw::PainterBlendShader::type ( void ) const

inline

Returns how the PainterBlendShader operates.
