Detailed Description

A PainterBrushAdjust holds the value for applying a tranformation to the brush position before it is handed off to brush shading. The transformation is shearing composited with a translation, i.e. the transformation is given by.

out_value = m_shear * in_value + m_translate

Member Enumeration Documentation

◆ data_offset_t

enum fastuidraw::PainterBrushAdjust::data_offset_t

Enumeration that provides offsets for the values in a PainterBrushAdjust in units of uint32_t.

Enumerator
shear_x_offset	offset of m_shear.x() (packed as float)
shear_y_offset	offset of m_shear.y() (packed as float)
translation_x_offset	offset of m_translation.x() (packed as float)
translation_y_offset	offset of m_translation.y() (packed as float)
raw_data_size	size of the raw data before padding

Definition at line 52 of file painter_brush_adjust.hpp.

Constructor & Destructor Documentation

◆ PainterBrushAdjust()

fastuidraw::PainterBrushAdjust::PainterBrushAdjust ( void )

inlineexplicit

Ctor, initializes the adjustment as identity

Definition at line 65 of file painter_brush_adjust.hpp.

Member Function Documentation

◆ data_size()

unsigned int fastuidraw::PainterBrushAdjust::data_size ( void ) const

inline

Returns the length of the data needed to encode the data. Data is padded to be multiple of 4.

Definition at line 75 of file painter_brush_adjust.hpp.

◆ pack_data()

void fastuidraw::PainterBrushAdjust::pack_data ( c_array< uvec4 > dst ) const

Pack the values of this PainterItemMatrix

Parameters

dst	place to which to pack data

Member Data Documentation

◆ m_shear

vec2 fastuidraw::PainterBrushAdjust::m_shear

The shearing to apply to the brush before the translation.

Definition at line 91 of file painter_brush_adjust.hpp.

◆ m_translate

vec2 fastuidraw::PainterBrushAdjust::m_translate

The translation to apply to the brush after applying the shearing.

Definition at line 97 of file painter_brush_adjust.hpp.
