Detailed Description

A 32-bit RGBA color bitmap graphics context that stores premultiplied alpha values. It is also used to store and test z-levels, which are represented using zero alpha levels and are not drawn.

Member Function Documentation

const MPalette* CartoType::C32BitColorBitmapGraphicsContext::BitmapPalette ( ) [inline, virtual]

Return a pointer to the palette associated with the bitmap owned by the graphics context. If the bitmap has no palette return null.

Implements CartoType::CLabelGraphicsContext.

void C32BitColorBitmapGraphicsContext::Clear ( ) [virtual]

Clear the drawing area to transparent black. If colors are not stored set all pixels to zero intensity. If transparency levels are not stored set all pixels to black.

Implements CartoType::CGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::DrawBitmap	(	const TBitmap &	aBitmap,
		const TPoint &	aTopLeft
	)		`[virtual]`

Draw a bitmap. If the bitmap has no color information use the current color. Combine any alpha information from the bitmap with the current alpha level. The coordinates are whole pixels.

Implements CartoType::CGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::DrawBitmapTextureUsingRamp	(	const TBitmap &	aBitmap,
		const TPointFP &	aTopLeft,
		const TTransformFP &	aTransform
	)		`[protected]`

Draw a bitmap texture, using a paint server as a color ramp. 8-bit pixel values are used as x coordinates for the paint server. The y coordinate is always zero.

TResult C32BitColorBitmapGraphicsContext::DrawRect ( const TRect & aRect ) [virtual]

Draw a filled rectangle in the current color. The coordinates are whole pixels.

Reimplemented from CartoType::CGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::DrawRectZ	(	const TRect &	aRect,
		uint32	aZ
	)		`[virtual]`

Set a Z value indicating a priority or other front-to-back ordering by setting all the pixels of a rectangle to the value aZ unless their existing value is higher.

Implements CartoType::CLabelGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::DrawShape	(	const MPath &	aPath,
		uint32	aFlags
	)		`[virtual]`

Draw a filled shape in the current color.

Implements CartoType::CGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::DrawShapeZ	(	const MPath &	aPath,
		uint32	aFlags,
		uint32	aZ
	)		`[virtual]`

Set a Z value indicating a priority or other front-to-back ordering by setting all the non-transparent pixels of a shape to the value aZ unless their existing value is higher.

Implements CartoType::CLabelGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::DrawTexture	(	const CTexture &	aTexture,
		const TPointFP &	aTopLeft,
		const TTransformFP &	aTransform
	)		`[virtual]`

Draw a texture at aTopLeft, transforming it by aTransform. The baseimplementation returns KErrorUnimplemented.

Reimplemented from CartoType::CGraphicsContext.

void C32BitColorBitmapGraphicsContext::SetGlow	(	TColor	aColor,
		TFixed	aWidth,
		const TPointFixed &	aOffset
	)		`[virtual]`

Set the current glow parameters. Bitmaps are drawn with a glowing border if the glow color is not fully transparent and the glow width is greater than zero.

Implements CartoType::CLabelGraphicsContext.

void C32BitColorBitmapGraphicsContext::Sync ( ) [virtual]

Synchronize the private graphics state to take account of any changes in iChangeFlags.

Implements CartoType::CGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::TestBitmap	(	const TBitmap &	aBitmap,
		const TPoint &	aTopLeft,
		bool	aCanOverlapEdge
	)		`[virtual]`

Find out whether any of the non-transparent pixels of aBitmap would overlap pixels with a non-zero value and return KErrorOverlap if so, or if aCanOverlapEdge is false and aBitmap is partly outside the drawable area of the GC. If not, return KErrorNone or an error code if some actual error occurred.

Implements CartoType::CLabelGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::TestRectZ	(	const TRect &	aRect,
		bool	aCanOverlapEdge,
		uint32	aZ
	)		`[virtual]`

Find out whether any of the pixels of aRect would overlap pixels with a value of aZ or more and return KErrorOverlap if so. If not, return KErrorNone or an error code if some actual error occurred. If aCanOverlapEdge is true the rectangle may overlap the edge of the display.

Implements CartoType::CLabelGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::TestShapeZ	(	const MPath &	aPath,
		uint32	aFlags,
		uint32	aZ
	)		`[virtual]`

Find out whether any of the pixels drawn when drawing aPath would overlap pixels with a value of aZ or more and return KErrorOverlap if so. If not, return KErrorNone or an error code if some actual error occurred.

Implements CartoType::CLabelGraphicsContext.

TResult C32BitColorBitmapGraphicsContext::TestTexture	(	const CTexture &	aTexture,
		const TPointFP &	aTopLeft,
		const TTransformFP &	aTransform,
		bool	aCanOverlapEdge
	)		`[virtual]`

Find out whether any of the non-transparent pixels of aTexture would overlap pixels with a non-zero value and return KErrorOverlap if so, or if aCanOverlapEdge is false and aBitmap is partly outside the drawable area of the GC. If not, return KErrorNone or an error code if some actual error occurred.
