Platform Specific Limitations

Rotation is not supported.

3D functions are not supported.

Alpha Values can only be set globally (Top left alpha is used).

Member Function Documentation

◆ Clear()

virtual void CGUIBitmapPlaneDirectFb::Clear	(	const eC_UByte	ubRed = `0`,
		const eC_UByte	ubGreen = `0`,
		const eC_UByte	ubBlue = `0`,
		const eC_UByte	ubAlpha = `0`
	)

virtual

Clears this bitmap with the given color. Attention: Please note that clearing Alpha values is unfortunately not supported by all Graphics APIs!

Parameters

ubRed	is the red part of the clear color
ubGreen	is the green part of the clear color
ubBlue	is the blue part of the clear color
ubAlpha	is the alpha part of the clear color

Reimplemented from CGUIBitmapPlane.

◆ DoDraw()

void CGUIBitmapPlaneDirectFb::DoDraw ( )

virtual

Draws this BitmapPlane. The Bitmap will be drawn to the current RenderTarget, with the set rotation and position. The set cliprect also applies to this drawing.

Reimplemented from CGUIBitmapPlane.

◆ DrawToBitmap()

virtual eC_Bool CGUIBitmapPlaneDirectFb::DrawToBitmap ( )

protectedvirtual

Called by the framework when the drawing operation into the bitmapplane is about to begin.

Returns: always true

Reimplemented from CGUIBitmapPlane.

◆ DrawToScreen()

virtual eC_Bool CGUIBitmapPlaneDirectFb::DrawToScreen ( )

protectedvirtual

Called by the framework when subsequent drawing operations shall happen on the normal UI screen.

Returns: always true

Reimplemented from CGUIBitmapPlane.

◆ FinishDrawToBitmap()

virtual eC_Bool CGUIBitmapPlaneDirectFb::FinishDrawToBitmap ( )

protectedvirtual

Called by the framework when the drawing operation into the bitmapplane has finished.

Returns: always true

Reimplemented from CGUIBitmapPlane.

◆ SetAlphaValues()

virtual void CGUIBitmapPlaneDirectFb::SetAlphaValues	(	const eC_UByte	ubTopLeft,
		const eC_UByte	ubBottomLeft,
		const eC_UByte	ubBottomRight,
		const eC_UByte	ubTopRight
	)

inlinevirtual

Please note: In DirectFB only one alpha value for the whole plane is supported. This implementation takes the value in "ubTopLeft"

Parameters

ubTopLeft
ubBottomLeft
ubBottomRight
ubTopRight

Reimplemented from CGUIBitmapPlane.
