Detailed Description

STM32F429 implementation of the graphics wrapper.

Platform Specific Limitations

Since BLU does not support RotBlits, it is not possible to rotate image at runtime; BlitImgExtImpl() must be only called with vAngle set to 0.

For additional details see description of base class CGfxWrap.

See CGfxWrap_stm32f429 Platform Specific Limitations

virtual

Draws a rectangle with the top left edge at (vAbsX1, vAbsY1) and bottom right edge at (vAbsX2, vAbsY2). The bottom edge and the right edge is not included in the drawn rect. e.g. Rect(0, 0, 10, 10); the rect is drawn from (0,0) to (9,9) (both included).

See also: CGUIObject::GetAbsRect()

Parameters

vAbsX1	X-coordinate of top left corner
vAbsY1	Y-Coordinate of top left corner
vAbsX2	X-coordinate of bottom right corner
vAbsY2	Y-Coordinate of bottom right corner

Reimplemented from CGfxWrapBLU.

◆ Refresh()

virtual eC_Bool CGfxWrap_stm32f429::Refresh ( const RefreshCall_t eRefreshCallType )

virtual

Method to bring the screen content onto the physical screen so that it becomes visible, usually via a blit operation.

Parameters

eRefreshCallType The call type of this refresh

Returns: True of the refresh was performed, False otherwise

Reimplemented from CGfxWrapBLU.

◆ SetCliprect()

virtual void CGfxWrap_stm32f429::SetCliprect ( const CGUIRect & NewAbsClipRect )

virtual

Sets a clipping rectangle. All drawing operations will be limited to the region within the clipping rectangle. This is very useful for advanced features such as soft-scrolling. Note that the clipping rectangle is not allowed to exceed the invalidated rectangle, since this would lead to visual artifacts.

Parameters

NewAbsClipRect A normalised rectangle that includes all pixels that could be drawn by the functions of the graphics wrapper. The rectangle includes the border. All pixels outside will be left untouched.

Reimplemented from CGfxWrapBLU.

◆ SetForegroundColorImpl()

virtual void CGfxWrap_stm32f429::SetForegroundColorImpl	(	const eC_UByte &	ubRed,
		const eC_UByte &	ubGreen,
		const eC_UByte &	ubBlue,
		const eC_UByte &	ubAlpha = `255`
	)

virtual

Sets the foreground color. This MUST be implemented by all graphics wrappers. For detailed explanations, please refer to CGfxWrap::SetForegroundColor

Parameters

ubRed	Red intensity within a range of 0 - 255
ubGreen	Green intensity within a range of 0 - 255
ubBlue	Blue intensity within a range of 0 - 255
ubAlpha	Alpha intensity within a range of 0 (transparent) - 255 (opaque)
