dTransferToImage (Function)

In french: dTransfertVersImage

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.

Example

// Summary: Method to implement to store the received 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, imgBVR32, 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 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:
imgBGR32 Image in 32-bit Blue Green Red format without alpha layer.
imgBGR Image in 24-bit Blue Green Red format.
imgBGRA Image in 32-bit Blue Green Red format with alpha channel.
imgRGB32 Image in 32-bit Red Green Blue format without alpha channel.

<Width>: Integer
