Members

Member	Description
view_mode	Correction mode of the region This member cannot be set to HI_FISHEYE_VIEW_MODE_NO_TRANS.
in_radius	In 360º mode, this parameter indicates the inner radius of the original image corresponding to the correction region. In other modes, this parameter is invalid. Value range: [0, out_radius)
out_radius	In 360º mode, this parameter indicates the outer radius of the original image corresponding to the correction region. In other modes, this parameter indicates the visible radius of the correction region. Value range: [1, 3 x max(width of input image/4, height of input image/4)]
pan	Pan value of the correction region. Value range: [0, 360]
tilt	Tilt value of the correction region. Value range: [0, 360]
hor_zoom	Horizontal zoom of the correction region. Value range: [1, 4095]
ver_zoom	Vertical zoom of the correction region. Value range: [1, 4095]
out_rect	Output position, width, and height of the correction region. Value range: The position, width, and height cannot exceed the range of the output image for fisheye correction. The start X coordinate must be 16-pixel aligned, and the start Y coordinate must be 2-pixel aligned.
