CYIPolygonFill Class Reference
Rendering

Detailed Description

A class that contains information on how to fill a polygon.

The polygon fill defined here will be drawn in software using CYICanvas.

Note
Does not use GPU / hardware acceleration.

Member Function Documentation

bool CYIPolygonFill::Create ( int32_t  nWidth,
int32_t  nHeight 
)

Allocates resources for a nWidth by nHeight pixels bitmap.

void CYIPolygonFill::Destroy ( )

Frees all the resources allocated in Create().

void CYIPolygonFill::Fill ( CYIBitmap *  pBitmap,
const CYIPolygonData *  pPolygonData,
const glm::vec4 &  bounds,
const CYIColor &  Color,
CYIGradient *  pGradient,
bool  bNonZeroFill 
)

Fills a polygon defined by pPolygonData inside pBitmap using the Color or pGradient.

Note
pGradient is optional. The polygon will be filled with pGradient only if bNonZeroFill is true and pGradient is not nullptr. If bNonZeroFill is false or pGradient is nullptr, the polygon will be filled with Color.

static void CYIPolygonFill::PolygonDataBounds ( const CYIPolygonData &  polygonDataIn,
glm::vec4 &  polygonBounds 
)
static

Calculates the polygon bounds based on polygonDataIn. The result is stored inside polygonBounds.
