static Bool readPlane ( Pel dst,
istream &  fd,
Bool  is16bit,
UInt  stride444,
UInt  width444,
UInt  height444,
UInt  pad_x444,
UInt  pad_y444,
const ComponentID  compID,
const ChromaFormat  destFormat,
const ChromaFormat  fileFormat,

)
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
dstdestination image plane
fdinput file stream
is16bittrue if input file carries > 8bit data, false otherwise.
stride444distance between vertically adjacent pixels of dst.
width444width of active area in dst.
height444height of active area in dst.
pad_x444length of horizontal padding.
pad_y444length of vertical padding.
compIDchroma component
destFormatchroma format of image
fileFormatchroma format of file
fileBitDepthcomponent 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 2shiftbits.

Parameters
imgpointer to image to be transformed
stridedistance between vertically adjacent pixels of img.
widthwidth of active area in img.
heightheight of active area in img.
shiftbitsif zero, no operation performed if > 0, multiply by 2shiftbits, see scalePlane() if < 0, divide and round by 2shiftbits and clip, see invScalePlane().
minvalminimum clipping value when dividing.
maxvalmaximum clipping value when dividing.
