Stored procedures
Creates an image from a buffer of pixels encoded in a specific format.
This function is an advanced function. This function is mainly used to handle the images returned by external APIs via Image variables.
// Summary: Method that must be implemented to store the incoming frame
// Syntax:
//__FrameSave (<nFrameNumber> is int, <stLock> is NUI_LOCKED_RECT, 
// <nImageType> is int, <nResolution> is int)
// 
// Parameters:
// nFrameNumber (integer): Number of the frame
// stLock (NUI_LOCKED_RECT): Data of the frame
// nImageType (integer): Type of image
// nResolution (integer): Image resolution

VIRTUAL PROTECTED procedure __FrameSave(LOCAL nFrameNumber is <useful> int, ...
		LOCAL stLock is NUI_LOCKED_RECT, local nImageType is <useful> int, ...
		LOCAL nResolution is <useful> int)

nWidth is unsigned int
nHeight is unsigned int
NuiImageResolutionToSize(nResolution, nWidth, nHeight)

// Stores the data
Transfer(&m_arrData, stLock.pBits, stLock.size)

SWITCH nImageType
	// RVB
	CASE NUI_IMAGE_TYPE_COLOR

	// Transfers the pixels into the image
	m_Pool = dTransferToImage(stLock.pBits, imgBGR32, nWidth, nHeight)

	OTHER CASE
	 // Not supported
END

// Draw the FPS
__DrawingFPS(m_Pool)
Syntax
<Result> = dTransferToImage(<Pointer> , <Type> , <Width> , <Height>)
<Result>: Image variable
Name of the Image variable containing the image created from the buffer. An invalid image is returned if an error occurred.
<Pointer>: Address
Address of the buffer containing the pixels to load.
<Type>: Integer constant
Type of buffer used:
imgBGR32Image in 32-bit Blue Green Red format without alpha channel.
imgBGRImage in 24-bit Blue Green Red format.
imgBGRAImage in 32-bit Blue Green Red format with alpha channel.
imgRGB32Image in 32-bit Red Green Blue format without alpha channel.
<Width>: Integer
Width of image.
<Height>: Integer
Height of image.
