; Name...........: _GDIPlus_BitmapCreateFromScan0
; Description ...: Creates a Bitmap object based on an array of bytes along with size and format information
; Syntax.........: _GDIPlus_BitmapCreateFromScan0($iWidth, $iHeight[, $iStride = 0[, $iPixelFormat = 0x0026200A[, $pScan0 = 0]]])
; Parameters ....: $iWidth - The bitmap width, in pixels
; $iHeight - The bitmap height, in pixels
; $iStride - Integer that specifies the byte offset between the beginning of one scan line and the next. This
; +is usually (but not necessarily) the number of bytes in the pixel format (for example, 2 for 16 bits per pixel)
; +multiplied by the width of the bitmap. The value passed to this parameter must be a multiple of four
; $iPixelFormat - Specifies the format of the pixel data. Can be one of the following:
; |$GDIP_PXF01INDEXED - 1 bpp, indexed
; |$GDIP_PXF04INDEXED - 4 bpp, indexed
; |$GDIP_PXF08INDEXED - 8 bpp, indexed
; |$GDIP_PXF16GRAYSCALE - 16 bpp, grayscale
; |$GDIP_PXF16RGB555 - 16 bpp; 5 bits for each RGB
; |$GDIP_PXF16RGB565 - 16 bpp; 5 bits red, 6 bits green, and 5 bits blue
; |$GDIP_PXF16ARGB1555 - 16 bpp; 1 bit for alpha and 5 bits for each RGB component
; |$GDIP_PXF24RGB - 24 bpp; 8 bits for each RGB
; |$GDIP_PXF32RGB - 32 bpp; 8 bits for each RGB. No alpha.
; |$GDIP_PXF32ARGB - 32 bpp; 8 bits for each RGB and alpha
; |$GDIP_PXF32PARGB - 32 bpp; 8 bits for each RGB and alpha, pre-mulitiplied
; $pScan0 - Pointer to an array of bytes that contains the pixel data. The caller is responsible for
; +allocating and freeing the block of memory pointed to by this parameter.
; Return values .: Success - Returns a handle to a new Bitmap object
; Failure - 0 and either:
; |@error and @extended are set if DllCall failed
; |$GDIP_STATUS contains a non zero value specifying the error code
; Remarks .......: After you are done with the object, call _GDIPlus_ImageDispose to release the object resources
; Related .......: _GDIPlus_ImageDispose
; Link ..........; @@MsdnLink@@ GdipCreateBitmapFromScan0
; Example .......; Yes
; ===============================================================================================================================
