QpOffsetRect
class QpOffsetRect
QpOffsetRect constitutes the metadata required for encoding a region of interest in an image or a video frame. The region of interest is represented by a rectangle. The four integer coordinates of the rectangle are stored in fields left, top, right, bottom. Note that the right and bottom coordinates are exclusive. This is paired with a suggestive qp offset information that is to be used during encoding of the blocks belonging to the to the box.

QpOffsetRect
QpOffsetRect(
contour: Rect,
qpOffset: Int)
Create a new region of interest with the specified coordinates and qpOffset. Note: no range checking is performed, so the caller must ensure that left >= 0, left <= right, top >= 0 and top <= bottom. Note that the right and bottom coordinates are exclusive.
Parameters |
contour |
Rect: Rectangle specifying the region of interest This value cannot be null . |
qpOffset |
Int: qpOffset to be used for the blocks in the specified rectangle |
