C Prototype |
hi_s32 hi_mpi_vpc_get_rotation_matrix(hi_float_point center_point, hi_double angle, hi_double scale, hi_transform_matrix *matrix) |
|---|---|
Python Function |
matrix, ret = acl.himpi.vpc_get_rotation_matrix(center_point, angle, scale) |
Function Usage |
Obtains the rotation matrix required for affine transformation. The Atlas 200/300/500 Inference Product does not support this API. The Atlas Training Series Product does not support this API. |
Input Description |
center_point: dict, dictionary of the rotation center point of the input image. For details, see hi_float_point. angle: float, rotation angle. A positive value indicates anticlockwise rotation. scale: float, resizing parameter. If the value of scale is greater than 1, the image is resized up. If the value of scale is less than 1, the image is resized down. |
Return Value |
matrix: dict, dictionary of the matrix required for affine transformation. Set matrix_type based on the actual input matrix. For details, see hi_transform_matrix. ret: int, error code.
