Member Function Documentation

void GrDrawContext::clear	(	const SkIRect *	rect,
		GrColor	color,
		bool	canIgnoreRect
	)

Clear the entire or rect of the render target, ignoring any clips.

Parameters

rect	the rect to clear or the whole thing if rect is NULL.
color	the color to clear to.
canIgnoreRect	allows partial clears to be converted to whole clears on platforms for which that is cheap

void GrDrawContext::drawArc	(	const GrClip &	,
		const GrPaint &	paint,
		const SkMatrix &	viewMatrix,
		const SkRect &	oval,
		SkScalar	startAngle,
		SkScalar	sweepAngle,
		bool	useCenter,
		const GrStyle &	style
	)

Draws a partial arc of an oval.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix.
oval	the bounding rect of the oval.
startAngle	starting angle in degrees.
sweepAngle	angle to sweep in degrees. Must be in (-360, 360)
useCenter	true means that the implied path begins at the oval center, connects as a line to the point indicated by the start contains the arc indicated by the sweep angle. If false the line beginning at the center point is omitted.
style	style to apply to the oval.

void GrDrawContext::drawAtlas	(	const GrClip &	,
		const GrPaint &	paint,
		const SkMatrix &	viewMatrix,
		int	spriteCount,
		const SkRSXform	xform[],
		const SkRect	texRect[],
		const SkColor	colors[]
	)

Draws textured sprites from an atlas with a paint.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix
spriteCount	number of sprites.
xform	array of compressed transformation data, required.
texRect	array of texture rectangles used to access the paint.
colors	optional array of per-sprite colors, supercedes the paint's color field.

void GrDrawContext::drawDRRect	(	const GrClip &	,
		const GrPaint &	,
		const SkMatrix &	viewMatrix,
		const SkRRect &	outer,
		const SkRRect &	inner
	)

Shortcut for drawing an SkPath consisting of nested rrects using a paint.

Does not support stroking. The result is undefined if outer does not contain inner.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix
outer	the outer roundrect
inner	the inner roundrect

void GrDrawContext::drawOval	(	const GrClip &	,
		const GrPaint &	paint,
		const SkMatrix &	viewMatrix,
		const SkRect &	oval,
		const GrStyle &	style
	)

Draws an oval.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix
oval	the bounding rect of the oval.
style	style to apply to the oval. Currently path effects are not allowed.

void GrDrawContext::drawPath	(	const GrClip &	,
		const GrPaint &	,
		const SkMatrix &	viewMatrix,
		const SkPath &	,
		const GrStyle &	style
	)

Draws a path.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix

		const SkRect &	,
		const GrStyle *	style = `nullptr`
	)

Draw the rect using a paint.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix
style	The style to apply. Null means fill. Currently path effects are not allowed. The rects coords are used to access the paint (through texture matrix)

		const SkRRect &	rrect,
		const GrStyle &	style
	)

Draw a roundrect using a paint.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix
rrect	the roundrect to draw

		GrPrimitiveType	primitiveType,
		int	vertexCount,
		const SkPoint	positions[],
		const SkPoint	texs[],
		const GrColor	colors[],
		const uint16_t	indices[],
		int	indexCount
	)

Draws vertices with a paint.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix
primitiveType	primitives type to draw.
vertexCount	number of vertices.
positions	array of vertex positions, required.
texCoords	optional array of texture coordinates used to access the paint.
colors	optional array of per-vertex colors, supercedes the paint's color field.
indices	optional array of indices. If NULL vertices are drawn non-indexed.
indexCount	if indices is non-null then this is the number of indices.

void GrDrawContext::fillRectToRect	(	const GrClip &	,
		const GrPaint &	paint,
		const SkMatrix &	viewMatrix,
		const SkRect &	rectToDraw,
		const SkRect &	localRect
	)

Maps a rectangle of shader coordinates to a rectangle and fills that rectangle.

Parameters

paint	describes how to color pixels.
viewMatrix	transformation matrix which applies to rectToDraw
rectToDraw	the rectangle to draw
localRect	the rectangle of shader coordinates applied to rectToDraw
