		istream &	fd,
		Bool	is16bit,
		UInt	stride444,
		UInt	width444,

		UInt	pad_y444,
		const ComponentID	compID,
		const ChromaFormat	destFormat,
		const ChromaFormat	fileFormat,
		const UInt	fileBitDepth
	)

static

Read width*height pixels from fd into dst, optionally padding the left and right edges by edge-extension. Input may be either 8bit or 16bit little-endian lsb-aligned words.

Parameters

dst	destination image plane
fd	input file stream
is16bit	true if input file carries > 8bit data, false otherwise.
stride444	distance between vertically adjacent pixels of dst.
width444	width of active area in dst.
height444	height of active area in dst.
pad_x444	length of horizontal padding.
pad_y444	length of vertical padding.
compID	chroma component
destFormat	chroma format of image
fileFormat	chroma format of file
fileBitDepth	component bit depth in file

Returns: true for success, false in case of error

static Void scalePlane	(	Pel *	img,
		const UInt	stride,
		const UInt	width,
		const UInt	height,
		Int	shiftbits,
		Pel	minval,
		Pel	maxval
	)

static

Scale all pixels in img depending upon sign of shiftbits by a factor of 2^shiftbits.

Parameters

img	pointer to image to be transformed
stride	distance between vertically adjacent pixels of img.
width	width of active area in img.
height	height of active area in img.
shiftbits	if zero, no operation performed if > 0, multiply by 2^shiftbits, see scalePlane() if < 0, divide and round by 2^shiftbits and clip, see invScalePlane().
minval	minimum clipping value when dividing.
maxval	maximum clipping value when dividing.

	)

static

Write an image plane (width444*height444 pixels) from src into output stream fd.

Parameters

fd	output file stream
src	source image
is16bit	true if input file carries > 8bit data, false otherwise.
stride444	distance between vertically adjacent pixels of src.
width444	width of active area in src.
height444	height of active area in src.
compID	chroma component
srcFormat	chroma format of image
fileFormat	chroma format of file
fileBitDepth	component bit depth in file

Returns: true for success, false in case of error
