DrawPixels::Pixels::Pixels	(	ImagePBO *	img,
		int	scrx,
		int	scry,
		int	startx = 0,
		int	starty = 0,
		int	width = -1,
		int	height = -1,
		int	alignment = AlignBottom | AlignLeft
	)

Constructor.

The parameters 'scrx' and 'scry' define the position of the viewport in pixels where the image has to be placed. If a Transform is attached to the Actor using DrawPixels scrx, scry follow the transform on the screen. The parameters 'startx', 'starty', 'width' and 'height' define the sub-portion of the Image to be rendered. The parameters 'width' and 'height' can be -1, in this case they will be automatically set so that the Image is shown until the top-right edge.

bool DrawPixels::Pixels::generatePixelBufferObject	(	EBufferObjectUsage	usage,
		bool	discard_local_storage
	)

Generates a pixel buffer object for the associated Image calling image()->bufferObject()->setBufferData(usage, discard_local_storage);.

Note:

All the Pixels object sharing the same Image will use the Image's PBO
