Members

Member	Description
view_mode	Correction mode of the region. This member cannot be set to HI_FISHEYE_VIEW_MODE_NO_TRANS.
in_radius	360° panoramic mode: inner radius of the original image corresponding to the correction region. Other modes: invalid Value range: [0, out_radius).
out_radius	Outside radius of the source image corresponding to the correction region in 360° panoramic correction mode, and visible radius of the correction region in other modes. 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 value of the correction region. Value range: [1, 4095].
ver_zoom	Vertical zoom value 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.
